• "rsAccessDenied" error for SSRS 2008

  - by JackLocke

  Hi All, I have been trying to access SSRS Web Service URL hxxp://myServer:80/ReportServer (from Reporting Service Configuration Manager), but my IE always shows "rsAccessDenied" message saying that my account doesn't have privilage required to view. Here are my system specs. Its my laptop with Windows 7 x64, and SQL Server 2008 with SP1 and I am using Mixed Mode Authentication with My account as SysAdmin privilages and this is what I have been trying / tried ... (ofcourse with restarting the service everytime I make any change in configuration), I changed service account from Reporting Service Configuration Manager to make it use My account but nothing happend. I tried running my IE as admin, by RUN AS ADMIN but still same message. Then I read somewhere I have to delete/recreate my encryption keys as well, so I tried again with that, then it was asking me to enter ID/PWD to access server here I am totally blank because it was not accepting my account credentials !!!. Weird thing is I can see my existing reports if I follow this URL hxxp://myServer:80/Reports , for which My guess is solely used to view reports. I have read post here about kind of same problem, but it seems that OP just left forum after asking question... Also, MSDN does have these helps hxxp://msdn.microsoft.com/en-us/library/ms156034.aspx hxxp://msdn.microsoft.com/en-us/library/bb630430.aspx but both of this didn't workout for me. I will really appriciate it if any one can help me out. Jack p.s. I was not allowed to post more than 1 URL because of my "reputation" so I had to change the string a bit. Please replace hxxp wih http in URLs.

• Possible to capture all events in a web browser?

  - by David

  I am working on a pet project and am at the research stage. Quick summary I am trying to intercept all form submits, onclick, and every single keydown. My library of choice is either jquery, or jquery + prototypejs. I figure I can batch up the events into a queue/stack and send it back to the server in time interval batches to keep performance relatively stable. Concerns Form submits and change's would be relatively simple.. Something like $("form :inputs").bind("change", function() { ... record event... }); But how to ensure I get precedence over the applications handlers as I have a habit of putting return false on a lot of my form handlers when there is a validation issue. As I understand it, that effectively stops the event in its tracks. My project For my smaller remote clients I will put their products onto a VPS or run it in my home data center. Currently I use a basic authentication system, given a username/password they see the website and then hopefully send me somewhat sane notes on what is broken or should be tweaked. As a better solution, I've written a simple proxy web server that does the above but allows me to have one DNS entry and then depending on credentials it makes an internal request relaying headers and re-writing URLS as needed. Every single html/text or application/* request is compressed and shoved into a sqlite table so I can partially replay what they've done. Now I am shifting to the frontend and would like to capture clicks, keydown's, and submits on everything on the page.

• How to Connect to a web service (SSL enabled and proxy interface)

  - by blgnklc

  There is a web service running on tomcat on a server. It is built on Java Servlet. It is listening others to call itself on a SSL enabled http port. so its web service adreess looks like: https://172.29.12.12/axis/services/XYZClient?wsdl On the other hand I want to connect the web service above from a windows application which is built on .NET frame work. Finally, when I want to connect the web service from my computer; I get some specific erros; Firstly I get; Proxy authentication error; then I added some new line to my code; Dim cr As System.Net.NetworkCredential = New System.Net.NetworkCredential("xname", "xsurname", "xdomainname") Dim myProxy As New WebProxy("http://mar.xxxyyy.com", True) myProxy.Credentials = cr Secondly, after this modifications It says that bad request. I did not get over this error. Moreover I did try to connect the web server on the same computer. I copied my executable program to the computer where the web service runs. The error was like; The underlying connection was closed: Could not establish trust relationship for SSL/TLS secure channel PS: When I try to connect to web service by using Internet Explorer; I see firstly some warnings about accepting an unknown certificate and I click take me to web service an I get there clearly. I want to know what are the basic elements to connect a web service, could you please tell me the requirements that I have to use on my windows project. regards bk

• Applying fine-grained security to an existing application

  - by Mark

  I've inherited a reasonably large and complex ASP.NET MVC3 web application using EF Code First on SQL Server. It uses ASP.NET Membership roles with database authentication. The controller actions are secured with attributes derived from AuthorizeAttribute that map roles to actions. There are extension methods for the finer points, such as showing a particular widget to particular roles. This is works great and I have a good understanding of the current security model. I've been asked to provide finer grained security at the data level. For example a 'Customer' user can only see data (throughout the database) associated with themselves and not other Customers. The problem is that 'Customer' is only 1 of 5 different types with their own specific restrictions (each of the 9 roles is one of these 5 types). The best thing I can think of is to go through all the data repositories and extend each and every LINQ statements/query with a filter for every user type. Even if I had time for that it doesn't seem like the most elegant way. Any suggestions? I really don't know where to start with this so anything could be helpful. Many thanks.

• Gdata JavaScript Authsub continues redirect

  - by Krustal

  I am using the JavaScript Google Data API and having issues getting the AuthSub script to work correctly. This is my script currently: google.load('gdata', '1'); function getCookie(c_name){ if(document.cookie.length>0){ c_start=document.cookie.indexOf(c_name + "="); if(c_start!=-1){ c_start=c_start + c_name.length+1; c_end=document.cookie.indexOf(";",c_start); if(c_end==-1) c_end=document.cookie.length; return unescape(document.cookie.substring(c_start, c_end)); } } return ""; } function main(){ var scope = 'http://www.google.com/calendar/feeds/'; if(!google.accounts.user.checkLogin(scope)){ google.accounts.user.login(); } else { /* * Retrieve all calendars */ // Create the calendar service object var calendarService = new google.gdata.calendar.CalendarService('GoogleInc-jsguide-1.0'); // The default "allcalendars" feed is used to retrieve a list of all // calendars (primary, secondary and subscribed) of the logged-in user var feedUri = 'http://www.google.com/calendar/feeds/default/allcalendars/full'; // The callback method that will be called when getAllCalendarsFeed() returns feed data var callback = function(result) { // Obtain the array of CalendarEntry var entries = result.feed.entry; //for (var i = 0; i < entries.length; i++) { var calendarEntry = entries[0]; var calendarTitle = calendarEntry.getTitle().getText(); alert('Calendar title = ' + calendarTitle); //} } // Error handler to be invoked when getAllCalendarsFeed() produces an error var handleError = function(error) { alert(error); } // Submit the request using the calendar service object calendarService.getAllCalendarsFeed(feedUri, callback, handleError); } } google.setOnLoadCallback(main); However when I run this the page redirects me to the authentication page. After I authenticate it send me back to my page and then quickly sends me back to the authenticate page again. I've included alerts to check if the token is being set and it doesn't seem to be working. Has anyone has this problem?

• Parallel.Foreach loop creating multiple db connections throws connection errors?

  - by shawn.mek

  Login failed. The login is from an untrusted domain and cannot be used with Windows authentication I wanted to get my code running in parallel, so I changed my foreach loop to a parallel foreach loop. It seemed simple enough. Each loop connects to the database, looks up some stuff, performs some logic, adds some stuff, closes the connection. But I get the above error? I'm using my local sql server and entity framework (each loop uses it's own context). Is there some problem with connecting multiple times using the same local login or something? How did I get around this? I have (before trying to covert to a parallel.foreach loop) split my list of objects that I am foreach looping through into four groups (separate csv files) and run four concurrent instances of my program (which ran faster overall than just one, thus the idea for parallel). So it seems connecting to the db shouldn't be a problem? Any ideas? EDIT: Here's before var gtgGenerator = new CustomGtgGenerator(); var connectionString = ConfigurationManager.ConnectionStrings["BioEntities"].ConnectionString; var allAccessionsFromObs = _GetAccessionListFromDataFiles(collectionId); ForEach(cloneIdAndAccessions in allAccessionsFromObs) DoWork(gtgGenerator, taxonId, organismId, cloneIdAndAccessions, connectionString)); after var gtgGenerator = new CustomGtgGenerator(); var connectionString = ConfigurationManager.ConnectionStrings["BioEntities"].ConnectionString; var allAccessionsFromObs = _GetAccessionListFromDataFiles(collectionId); Parallel.ForEach(allAccessionsFromObs, cloneIdAndAccessions => DoWork(gtgGenerator, taxonId, organismId, cloneIdAndAccessions, connectionString)); Inside the DoWork I use the BioEntities using (var bioEntities = new BioEntities(connectionString)) {...}

• Componentizing complex functionality in an MVC web app

  - by NXT

  Hi Everyone, This is question about MVC web-app architecture, and how it can be extended to handle componentizing moderately complex units of functionality. I have an MVC style web-app with a customer facing credit card charge page. I've been asked to allow the admins to enter credit card payments as well, for times when credit cards are taken over the phone. The customer facing credit card charge section of the website is currently it's own controller, with approximately 3 pages and a login. That controller is responsible for: Customer login credential authentication Credit card data collection Calling a library to do the actual charge. reporting the results to the user. I would like to extract the card data collection pages into a component of some kind so that I can easily reuse the code on the admin side of the app. Right now my components are limited to single "view" pages with PHP style embedded Perl code. This is a simple, custom MVC framework written in Perl. Right now, controllers are called directly from the framework to service web requests. My idea is to allow controllers to be called from other controllers, so that I can componentize more complex functionality. For simplicity I think I prefer composition over inheritance, even though it will require writing a bunch of pass-through methods (actions). Being Perl, I could in theory do multiple inheritance. I'm wondering if anyone with experience in other MVC web frameworks can comment on how this sort of thing is usually done. Thank you.

• Not able to connect to TFS Server from TFS Proxy

  - by GV India

  In our office we have setup TFS for project development. The TFS Server is WIN 2003 server SP2 with VSTFS 2008 and is running fine. Now we need to setup a TFS Proxy server on client site for client to access. Before going for the client setup, I wanted to build and test proxy in our office on a dummy server (will call it Proxy server hereon) by keeping it on a different domain. OS configuration of the Proxy server is the same as TFS server. I have installed and configured TFS proxy on Proxy server to connect to TFS Server. Also we have built trust between the two different domains to enable communication. Now problem is that I am not able to at all connect to TFS server. I am trying to connect from Internet Explorer of proxy server using proxy service account. It gives me error: The page cannot be displayed. HTTP 500 - Internal server error. The page I was browsing was http://tfs:8080/VersionControl/v1.0/ProxyStatistics.asmx. I think I have done all the required steps correctly to configure proxy as described in MSDN and also TFS installation guide. Here Proxy service account is a member of ‘Team Foundation Valid Users’ group. I am able to connect to TFS Server (specifying port) using Telnet from command prompt on proxy server as suggested by few sites. The TFS server web sites have been configured to use Integration Windows Authentication. Event Logs on both the servers are also not giving any error. Overall I’m not able to get it done. Any ideas on what might be the problem???

• Identity.Name is disposed in a IIS7 Asp.NET MVC application Thread

  - by vIceBerg

  I have made the smallest demo project to illustrate my problem. You can download the sources Here Visual Studio 2008, .NET 3.5, IIS7, Windows 7 Ultimate 32 bits. The IIS Website is configured ONLY for Windows Authentication in an Integreated pipeline app pool (DefaultAppPool). Here's the problem. I have an Asp.NET MVC 2 application. In an action, I start a thread. The View returns. The thread is doing it's job... but it needs to access Thread.CurrentPrincipal.Identity.Name BANG The worker process of IIS7 stops. I have a window that says: "Visual Studio Just-In-Time Debugger An unhandled exception ('System.Object.DisposedException') occured in w3wp.exe [5524]" I checked with the debugger and the Thread.CurrentPrincipal.Identity is valid, but the Name property is disposed. If I put a long wait in the action before it returns the view, then the Thread can do it's job and the Identity.Name is not disposed. So I think the Name gets disposed when the view is returned. For the sake of the discussion, here's the code that the thread runs (but you can also download the demo project. The link is on top of this post): private void Run() { const int SECTOWAIT = 3; //wait SECTOWAIT seconds long end = DateTime.Now.Ticks + (TimeSpan.TicksPerSecond * SECTOWAIT); while (DateTime.Now.Ticks <= end) continue; //Check the currentprincipal. BANG!!!!!!!!!!!!! var userName = Thread.CurrentPrincipal.Identity.Name; } Here's the code that starts the thread public void Start() { Thread thread = new Thread(new ParameterizedThreadStart(ThreadProc)); thread.SetApartmentState(ApartmentState.MTA); thread.Name = "TestThread"; thread.Start(this); } static void ThreadProc(object o) { try { Builder builder = (Builder)o; builder.Run(); } catch (Exception ex) { throw; } } So... what am i doing wrong?

• Using PHP and cURL to login to indyarocks.com

  - by Divya

  I am new to cURL and don't know much about it. I basically want to login to my account on www.indyarocks.com through libcurl for PHP. I don't know what type of authentication it uses (I don't know how to find that out.). When I go to http://www.indyarocks.com, I get a login form which asks for my username and password. I put in my username and password and click login and everything is good. I tried to automate this using cURL. This is a snippet of my code. curl_setopt($curl_connection, CURLOPT_URL, "http://www.indyarocks.com/loginchk.php"); curl_setopt($curl_connection, CURLOPT_POST, 1); curl_setopt($curl_connection, CURLOPT_HTTPAUTH, CURLAUTH_ANY); curl_setopt($curl_connection, CURLOPT_USERPWD, $username.':'.$password); I looked at the source of the login page and found out the address of the page to which the username and password are sent (the action attribute of the form) which is "http://www.indyarocks.com/loginchk.php" and set it as the target url. When I run this, I get username or password is wrong error and the login fails. My username and password is correct. I don't know what the problem is. Can the password be encrypted? Can that be responsible for this failure? Please help me get around this problem. I'll be really thankful. Thanks in advance.

• Apache is looking for htaccess and htpasswd files that aren't there

  - by user1094092

  Having an issue where Apache is requesting authentication, and looking for an .htpasswd file, based on instructions from an .htaccess file that's no longer in DocumentRoot. Background: In my DocumentRoot, I'd previously copied an .htaccess and .htpasswd file from another machine (along with all of the other website files). .htaccess contents: AuthType Basic AuthName "Password is required" AuthUserFile /some/directory/that/was/on/the/other/server/not/this/one/.htpasswd Require valid-user Here's the catch: I moved .htaccess and .htpasswd out of DocumentRoot and even renamed the files. There is no longer an .htaccess file in DocumentRoot at all. But, when I try to access localhost from a browser, I am prompted to enter the login and password. When I enter the login and password (from the old, not-in-DocumentRoot .hpasswd file), I get a 500 Internal Server error and the log shows: [error] [client 127.0.0.1] (2)No such file or directory: Could not open password file: /some/directory/that/was/on/the/other/server/not/this/one/.htpasswd This has been quite a puzzle, because there's no longer a .htaccess or .htpasswd file anywhere in DocumentRoot !! Have tried several apache restarts and also tried using a blank .htaccess file in the DocumentRoot. Even grepped the entire machine for references to AuthType Basic to see if I missed anything. httpd.conf looks normal enough...I can post that if needed, but this question seems long enough as it is :) Thanks for any assistance you can provide

• Credit Card storage solution

  - by jtnire

  Hi Everyone, I'm developing a solution that is designed to store membership details, as well as credit card details. I'm trying to comply with PCI DSS as much as I can. Here is my design so far: PAN = Primary account number == long number on credit card Server A is a remote server. It stores all membership details (Names, Address etc..) and provides indivudal Key A's for each PAN stored Server B is a local server, and actually holds the encrypted PANs, as well as Key B, and does the decryption. To get a PAN, the client has to authenticate with BOTH servers, ask Server A for the respective Key A, then give Key A to server B, which will return the PAN to the client (provided authentication was sucessful). Server A will only ever encrypt Key A with Server B's public Key, as it will have it beforehand. Server B will probably have to send a salt first though, however I doin't think that has to be encrypted I havn't really thought about any implementation (i.e. coding) specifics yet regarding the above, however the solution is using Java's Cajo framework (wrapper for RMI) so that is how the servers will communicate with each other (Currently, membership details are transfered in this way). The reason why I want Server B to do the decryption, and not the client, is that I am afraid of decryption keys going into the client's RAM, even though it's probably just as bad on the server... Can anyone see anything wrong with the above design? It doesn't matter if the above has to be changed. Thanks jtnire

• How do common web frameworks (Django, Rails, Symfony, etc) handle multiple instances of the same plu

  - by Steven Wei

  Do any of the popular web frameworks solve this problem well? Here's an example: suppose you're running one of these web frameworks and you want to install a blog plugin. Except instead of a single blog, you need to run two separate instances of the blog plugin, and you want to keep them segregated. Or say you want to install multiple instances of a user authentication plugin, because you want to segregate your administrative users from your customer user accounts. Or say you want to install multiple instances of a wiki plugin for different parts of your site, or multiple instances of a comments plugin, or whatever else. It seems to me that at the basic level, each instance of plugin would need to be able to configured with a different set of database tables, and would need to be 'installed' at a different URL path. My experience is mostly with Django and Symfony, and I haven't seen a clean solution to this problem in either of them. They both tend to assume that each plugin (or app, in Django's case) is only ever going to be installed once. I'm curious if the Rails folks have figured out a clean solution to this problem, or any other framework authors (in any language). And if you were going to design a solution to this problem, what would it look like?

• C++ socket concurrent server

  - by gregpi

  Hi all; Im writing a concurrent server that's supposed to have a communication channel and a data channel. The client initially connect to the communication channel to authenticate, upon successful authentication, the client is then connected to the data channel to access data. My program is already doing that, and im using threads.My only issue is that if I try to connect another client, I get a "cannot bind : address already in use" error. I have it this way: PART A Client connect to port 4567 (and enter his login info). A thread spawn to handle the client(repeated for each client that connects). In the thread created, I have a function(let's call it FUNC_A) that checks the client's login info(dont worry about how the check is done), if successful, the thread starts the data server(listening on 8976) then sends an OK to the client, once received the client attempts to connect to the data server. PART B Once a client connect to the data server, from inside FUNC_A the client is accepted and another thread is spawn to handle the client's connection to the data server.(hopefully everything is clear). Now, all that is working fine. However, if I try to connect with second client when it gets to PART B I get a "cannot bind error: address already in use". I've tried so many different ways, I've even tried spawning a thread to start the data server and accept the client and then start another thread to handle that connection. still no luck. Please give me a suggestion as to what I'm doing wrong, how do I go about doing this or what's the best way to implement it. Thank you

• How do I connect to SQL Server with VB?

  - by Wayne Werner

  Hi, I'm trying to connect to a SQL server from VB. The SQL server is across the network uses my windows login for authentication. I can access the server using the following python code: import odbc conn = odbc.odbc('SignInspection') c = conn.cursor() c.execute("SELECT * FROM list_domain") c.fetchone() This code works fine, returning the first result of the SELECT. However, I've been trying to use the SqlClient.SqlConnection in VB, and it fails to connect. I've tried several different connection strings but this is the current code: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim conn As New SqlClient.SqlConnection conn.ConnectionString = "data source=signinspection;initial catalog=signinspection;integrated security=SSPI" Try conn.Open() MessageBox.Show("Sweet Success") 'Insert some code here, woo Catch ex As Exception MessageBox.Show("Failed to connect to data source.") MessageBox.Show(ex.ToString()) Finally conn.Close() End Try End Sub It fails miserably, and it gives me an error that says "A network-related or instance-specific error occurred... (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) I'm fairly certain it's my connection string, but nothing I've found has given me any solid examples (server=mySQLServer is not a solid example) of what I need to use. Thanks! -Wayne

• ASP can't connect to SQL Server database

  - by birdus

  I'm trying to get a classic ASP application to connect to a local SQL Server 2008 database. The app and database were built by someone else. I'm just trying to get them installed and running on my machine (Windows 7). I'm getting the following error when when the ASP app tries to connect to the database: Could not connect to database: Error Number: -2147467259 Error Message: [ConnectionOpen (Connect()).] does not exist or access denied. I don't see any messages in the Windows Event Viewer. I'm looking at: Event Viewer-Windows Logs-Application. It's a fresh database install using a simple restore. The SQL Server install uses the default instance. SQL Server and Windows authentication are both allowed. I left the existing connection string (in the ASP code) in tact and just tried adding that to my SQL Server installation. Here's the connection string: strConn = "PROVIDER=SQLOLEDB;SERVER=localhost;UID=TheUser;PWD=ThePassword;DATABASE=TheDatabase;" To add that user to SQL Server, I went to Security/Logins in SSMS and added the user and the password. I selected the database in question as the Default database. I thought that might do the trick, but it didn't. Then, I went into TheDatabase, then went into Security there. I added a new user there, referencing the new user I had already added in server Security. Under Owned Schemas, I clicked db_owner and under Role Members I checked db_accessadmin and db_owner. None of this gave the ASP application access to the database. The sid values match in sys.database_principals and sys.server_principals for the login in question. I am able to login to SSMS using this login. The app needs to execute selects against the database like this: oConn.Execute('select * from someTable') I'm not a DBA and am sort of grasping at straws here. How do I get this thing connected? Thanks, Jay

• Approaches for cross server content sharing?

  - by Anonymity

  I've currently been tasked with finding a best solution to serving up content on our new site from another one of our other sites. Several approaches suggested to me, that I've looked into include using SharePoint's Lists Web Service to grab the list through javascript - which results in XSS and is not an option. Another suggestion was to build a server side custom web service and use SharePoint Request Forms to get the information - this is something I've only very briefly looked at. It's been suggested that I try permitting the requesting site in the HTTP headers of the serving site since I have access to both. This ultimately resulted in a semi-working solution that had major security holes. (I had to include username/password in the request to appease AD Authentication). This was done by allowing Access-Control-Allow-Origin: * The most direct approach I could think of was to simply build in the webpart in our new environment to have the authors manually update this content the same as they would on the other site. Are any one of the suggestions here more valid than another? Which would be the best approach? Are there other suggestions I may be overlooking? I'm also not sure if WebCrawling or Content Scrapping really holds water here...

• Is it better to use a relational database or document-based database for an app like Wufoo?

  - by mboyle

  I'm working on an application that's similar to Wufoo in that it allows our users to create their own databases and collect/present records with auto generated forms and views. Since every user is creating a different schema (one user might have a database of their baseball card collection, another might have a database of their recipes) our current approach is using MySQL to create separate databases for every user with its own tables. So in other words, the databases our MySQL server contains look like: main-web-app-db (our web app containing tables for users account info, billing, etc) user_1_db (baseball_cards_table) user_2_db (recipes_table) .... And so on. If a user wants to set up a new database to keep track of their DVD collection, we'd do a "create database ..." with "create table ...". If they enter some data in and then decide they want to change a column we'd do an "alter table ....". Now, the further along I get with building this out the more it seems like MySQL is poorly suited to handling this. 1) My first concern is that switching databases every request, first to our main app's database for authentication etc, and then to the user's personal database, is going to be inefficient. 2) The second concern I have is that there's going to be a limit to the number of databases a single MySQL server can host. Pretending for a moment this application had 500,000 user databases, is MySQL designed to operate this way? What if it were a million, or more? 3) Lastly, is this method going to be a nightmare to support and scale? I've never heard of MySQL being used in this way so I do worry about how this affects things like replication and other methods of scaling. To me, it seems like MySQL wasn't built to be used in this way but what do I know. I've been looking at document-based databases like MongoDB, CouchDB, and Redis as alternatives because it seems like a schema-less approach to this particular problem makes a lot of sense. Can anyone offer some advice on this?

  Hi! , i had successfully implemented simple open ID authentication with the [gmail , yahoo , myopenid, aol and many others ] exactly as stackoverflow do but i had a problem with identifying accounts for example 'openid_ns' => string 'http://specs.openid.net/auth/2.0' (length=32) 'openid_mode' => string 'id_res' (length=6) 'openid_op_endpoint' => string 'https://www.google.com/accounts/o8/ud' (length=37) 'openid_response_nonce' => string '2010-05-02T06:35:40Z9YIASispxMvKpw' (length=34) 'openid_return_to' => string 'http://dev.local/download/index/gettingback' (length=43) 'openid_assoc_handle' => string 'AOQobUf_2jrRKQ4YZoqBvq5-O9sfkkng9UFxoE9SEBlgWqJv7Sq_FYgD7rEXiLLXhnjCghvf' (length=72) 'openid_signed' => string 'op_endpoint,claimed_id,identity,return_to,response_nonce,assoc_handle' (length=69) 'openid_sig' => string 'knieEHpvOc/Rxu1bkUdjeE9YbbFX3lqZDOQFxLFdau0=' (length=44) 'openid_identity' => string 'https://www.google.com/accounts/o8/id?id=AItOawk0NAa51T3xWy-oympGpxFj5CftFsmjZpY' (length=80) 'openid_claimed_id' => string 'https://www.google.com/accounts/o8/id?id=AItOawk0NAa51T3xWy-oympGpxFj5CftFsmjZpY' (length=80) i thought that openid_claimed_id or openid_identity is identical for every account but after some testing turns out the claimed id is changeable by the users them self in yahoo and randomly changing in case of gmail FYI am using zend openid with a bit modification on consumer class and i can't use SERG [Simple Refistration Extension] cuz currently it uses openid v1 specification :( i hadn't read the specification of openid so if any body know please help me to how to identify openid accounts to know if this account has signed in before or not

• How to reliably identify users across Internet?

  - by amn

  I know this is a big one. In fact, it may be used for some SO community wiki. Anyways, I am running a website that DOES NOT use explicit authentication of users. It's public as in open to everybody. However, due to the nature of the service, some users need to be locked out due to misbehavior. I am currently blocking IP addresses, but I am aware of the supposed fact that many people purposefully reset their DHCP client cache to have their ISP assign them new addresses. Is that a fact? I think it certainly is a lucrative possibility for some people who want to circumvent being denied access. So IPs turn out to be a suboptimal way of dealing with this. But there is nothing else, is it? MAC addresses don't survive on WAN (change from hop to hop?), and even if they did - these can also be spoofed, although I think less easily than IP renewal. Cookies and even Flash cookies are out of the question, because there are tons of "tutorials" how to wipe these, and those intent on wreaking havoc on Internet are well aware and well equipped against such rudimentary measures I would employ. Is there anything else to lean on? I was thinking heuristical profiling - collecting available data from client-side and forming some key with it, but have not gone as far as to implementing it - is it an option?

• ASPX page renders differently when reached on intranet vs. internet?

  - by MattSlay

  This is so odd to me.. I have IIS 5 running on XP and it's hosting a small ASP.Net app for our LAN that we can access by using the computer name, virtual directory, and page name (http://matt/smallapp/customers.aspx), but you can also hit that IIS server and page from the internet because I have a public IP that my firewall routes to the "Matt" computer (like http://213.202.3.88/smallapp/customers.aspx [just a made-up IP]). Don't worry, I have Windows domain authentication is in place to protect the app from anonymous users. So all the abovea parts works fine. But what's weird is that the Border of the divs on the page are rendered much thicker when you access the page from the intranet, versus the internet, (I'm using IE8) and also, some of the div layout (stretching and such) acts differently. Why would it render different in the same browser based on whether it was reached from the LAN vs. the internet? It does NOT do this in FireFox. So it must be just an IE8 thing. All the CSS for the divs is right in the HTML page, so I do not think it is a caching matter of a CSS file. Notice how the borders are different in these two images: Internet: http://twitpic.com/hxx91 . Lan: http://twitpic.com/hxxtv

• @selector and return value

  - by user320926

  The idea it's very easy, i have an http download class, this class must support the http authentication but it's basically a background thread so i would like to avoid to prompt directly to the screen, i would like to use a delegate method to require from outside of the class, like a viewController. But i don't know if is possible or if i have to use a different syntax. This class use this delegate protocol: //Updater.h @protocol Updater <NSObject> -(NSDictionary *)authRequired; @optional -(void)statusUpdate:(NSString *)newStatus; -(void)downloadProgress:(int)percentage; @end @interface Updater : NSThread { ... } This is the call to the delegate method: //Updater.m // This check always fails :( if ([self.delegate respondsToSelector:@selector(authRequired:)]) { auth = [delegate authRequired]; } This is the implementation of the delegate method //rootViewController.m -(NSDictionary *)authRequired; { // TODO: some kind of popup or modal view NSMutableDictionary *ret=[[NSMutableDictionary alloc] init]; [ret setObject:@"utente" forKey:@"user"]; [ret setObject:@"password" forKey:@"pass"]; return ret; }

• JasperReports reports access image via authenticated URL

  - by user363115

  Hi all, I am hoping that this is a simple issue with a simple solution and that I have missed something obvious. Let me explain the problem; We have an application that generates PDF reports (using Jasper). These reports contain data from our database, as well as imagery (photographs). These photographs are stored in S3. We use signed URLs to access these photographs. We link these photographs into our Jasper reports using these S3 URLs. Because the S3 URLs are signed and time-limited (by design), the process is as follows; User requests a report to be generated, Report is filled, and goes to our database (at which time UUIDs to any required images are retrieved), For each UUID an S3 signed URL must be generated, To do this the URL behind each report image is a call to an authenticated URL in our app (/get_img?uuid=foo), The controller behind this URL generates a signed S3 URL and returns it, Reports loads the image. The problem is with step (4) - the call to the authenticated URL fails because Jasper does not pass any authentication information with the request. Is there a solution here? Thanks all for your time. Ben

• DotNetOpeId - Using OpenIdButton for Google Apps

  - by JediPotPie

  I am an ASP.NET newbie and I am trying to design an OpenID/SSO system for an internal web application. The web application is pretty simple and the authentication is currently being managed by a database with usernames and passwords. I want to replace the existing accounts stored in the database with Google Apps accounts. I have downloaded the latest DotNetOpenAuth-3.4.3.10103 package and got the OpenIdRelyingPartyWebForms sample up and running on IIS. I have built my own login page using just a OpenIdButton object that points to a development Google domain. The button seems to work fine in FireFox, at least it is forwarding me to the Google Apps login, but nothing happens when I load the same page in IE. When I click the Google button, nothing happens, zip. The same is true for the Yahoo button in the login.aspx page given in the sample. Here is the .aspx code I am using... <rp:OpenIdButton runat="server" ImageUrl="http://www.google.com/accounts/google_transparent.gif" Text="Login with Google!" ID="googleLoginButton" Identifier="https://www.google.com/accounts/o8/site-xrds?hd=dev.connexcloud.com" />
