  • OpenLDAP Authentication UID vs CN issues

    - by user145457
    I'm having trouble authenticating services using uid for authentication, which I thought was the standard method for authentication on the user. So basically, my users are added in ldap like this: # jsmith, Users, example.com dn: uid=jsmith,ou=Users,dc=example,dc=com uidNumber: 10003 loginShell: /bin/bash sn: Smith mail: [email protected] homeDirectory: /home/jsmith displayName: John Smith givenName: John uid: jsmith gecos: John Smith gidNumber: 10000 cn: John Smith title: System Administrator But when I try to authenticate using typical webapps or services like this: jsmith password I get: ldapsearch -x -h ldap.example.com -D "cn=jsmith,ou=Users,dc=example,dc=com" -W -b "dc=example,dc=com" Enter LDAP Password: ldap_bind: Invalid credentials (49) But if I use: ldapsearch -x -h ldap.example.com -D "uid=jsmith,ou=Users,dc=example,dc=com" -W -b "dc=example,dc=com" It works. HOWEVER...most webapps and authentication methods seem to use another method. So on a webapp I'm using, unless I specify the user as: uid=smith,ou=users,dc=example,dc=com Nothing works. In the webapp I just need users to put: jsmith in the user field. Keep in mind my ldap is using the "new" cn=config method of storing settings. So if someone has an obvious ldif I'm missing please provide. Let me know if you need further info. This is openldap on ubuntu 12.04. Thanks, Dave

  • How to Programmatically Split Data Using VBA Using Specific Logic

    - by Charlene
    This is an addition to my previous post here. The code that was previously supplied to me worked like a charm, but I am having issues modifying it adding some additional logic. I am creating a macro in VBA to do the following. I have raw order data that I need to transform based on some logic. Raw Data: order-id product-num date buyer-name prod-name qty-purc sales-tax freight order-st 0000000000-00 10000000000000 5/29/2014 John Doe Product 0 1 1.00 1.50 GA 0000000000-00 10000000000001 5/29/2014 John Doe Product 1 2 1.00 1.50 GA 0000000000-00 10000000000002 5/29/2014 John Doe Product 2 1 1.00 2.00 GA 0000000000-01 10000000000002 5/30/2014 Jane Doe Product 2 1 0.00 0.00 PA 0000000000-01 10000000000003 5/30/2014 Jane Doe Product 3 1 0.00 0.00 PA Desired Outcome: HDR 0000000000-00 John Doe 5/29/2014 CHG Tax 3.00 CHG Freight 5.00 ITM 10000000000000 Product 0 1 ITM 10000000000001 Product 1 2 ITM 10000000000002 Product 2 1 HDR 0000000000-01 Jane Doe 5/30/2014 ITM 10000000000002 Product 2 1 ITM 10000000000003 Product 3 1 The "CHG" rows are created based on the following logic; if the order-st is CA or GA, add the total of sales-tax and freight for each of the rows with the same order-id. If the order-st is NOT CA or GA, no CHG rows should be created. Any help would be appreciated - let me know if I left any details out!

  • How to Programmatically Split and Manipulate Rows of Data From Excel

    - by Charlene
    I am hoping one of you will be able to help get me started on this issue. I need to create some sort of macro or VBA code to split and manipulate rows of data in Excel. For this example, we have 5 rows of data. The first 3 rows are item information for Order # 0000000000-00 and the last 2 rows are item information for order # 0000000000-01. I need one row ("HDR") for each order number, and one row ("ITM") for each product per order. I have included an example below showing the data I will receive and the desired outcome. Raw Data: order-id product-num date buyer-name product-name quantity-purchased 0000000000-00 10000000000000 5/29/2014 John Doe Product 0 1 0000000000-00 10000000000001 5/29/2014 John Doe Product 1 2 0000000000-00 10000000000002 5/29/2014 John Doe Product 2 1 0000000000-01 10000000000002 5/30/2014 Jane Doe Product 2 1 0000000000-01 10000000000003 5/30/2014 Jane Doe Product 3 1 Desired Outcome: HDR 0000000000-00 John Doe 5/29/2014 ITM 10000000000000 Product 0 1 ITM 10000000000001 Product 1 2 ITM 10000000000002 Product 2 1 HDR 0000000000-01 Jane Doe 5/30/2014 ITM 10000000000002 Product 2 1 ITM 10000000000003 Product 3 1 Any and all help would be much appreciated!!! Thank you.

  • Excel 2007 pivot table does not aggregate properly

    - by Patrick
    I am using a an excel pivot table to summarize some data and just found a problem. The problem deals with how aggregate values are calculated. Let's say I have a table of data with three columns: Name, Date, Value. If I create a table where Name and then Date are used as Row Labels and Value is the aggregate value, ie Average. The pivot table will look something like this: +John .3450 5/14/2010 1.234 5/15/2010 3.450 5/16/2010 -3.25 What I think should be happening here is that the values for each date are averaged and then those values are averaged to come up with the value in the same row as the Name, John. But that is not what it does. It takes the average for each date, which it shows across from the date, but then instead of taking the average of those numbers, it actually uses the raw data and computes the average for all of John's values. It should show the average of the daily averages to correspond with the tree hierarchy, but instead just shows me the average for all of John's values. It essential will only aggregate at one level, but visually creates sub levels that it is not using. Does anyone know how to change this or understand by what logic this makes sense? Why would I create any sub groupings if I cannot compute aggregates on them?

  • Excel 2007 - Adding line breaks in a cell and no line over 50 characters

    - by Richard Drew
    I have notes stored in an excel cell. I add line breaks and dates every time I add a new note. I need to copy this to another program, but it has a line limit of 50 characters. I want a line break for each new date and for when each date's comment goes over 50 characters. I'm able to do one or the other, but I can't figure out how to do both. I'd prefer words not to be split up, but at this point I don't care. Below is some sample input. If needed for a SUBSTITUTE or REPLACE function, I could add a ~ before each date in my input as a delimiter. Sample Input: 07/03 - FU on query. Copies and history included. CC to Jane Doe and John Public 06/29 - Cust claiming not to have these and wrong PO on query form. Responded with inv sent dates and locations, correct PO values, and copies. 06/27 - New ticket opened using query form 06/12 - Opened ticket with helpdesk asking status 05/21 - Copy submitted to [email protected] 05/14 - Copy sent to John Public and [email protected] Ideal Output: 07/03 - FU on query. Copies and history included. CC to Jane Doe and John Public 06/29 - Cust claiming not to have these and wrong PO on query form. Responded with inv sent dates an d locations, correct PO values, and copies. 06/27 - New ticket opened using query form 06/12 - Opened ticket with helpdesk asking status 05/21 - Copy submitted to [email protected] om 05/14 - Copy sent to John Public and email@custome r.com

  • How to grant read/write to specific user in any existent or future subdirectory of a given directory? [migrated]

    - by Samuel Rossille
    I'm a complete newbie in system administration and I'm doing this as a hobby. I host my own git repository on a VPS. Let's say my user is john. I'm using the ssh protocol to access my git repository, so my url is something like ssh://[email protected]/path/to/git/myrepo/. Root is the owner of everything that's under /path/to/git I'm attempting to give read/write access to john to everything which is under /path/to/git/myrepo I've tried both chmod and setfacl to control access, but both fail the same way: they apply rights recursively (with the right options) to all the current existing subdirectories of /path/to/git/myrepo, but as soon as a new directory is created, my user can not write in the new directory. I know that there are hooks in git that would allow me to reapply the rights after each commit, but I'm starting to think that i'm going the wrong way because this seems too complicated for a very basic purpose. Q: How should I setup my right to give rw access to john to anything under /path/to/git/myrepo and make it resilient to tree structure change ? Q2: If I should take a step back change the general approach, please tell me.

  • C# Linq List Contains Similar Elements

    - by John Peters
    Hi All, I am looking for linq query to see if there exists a similar object I have an object graph as follows Cart myCart = new Cart { List<CartProduct> myCartProduct = new List<CartProduct> { CartProduct cartProduct1 = new CartProduct { List<CartProductAttribute> a = new List<CartProductAttribute> { CartProductAttribute cpa1 = new CartProductAttribute{ title="red" }, CartProductAttribute cpa2 = new CartProductAttribute{ title="small" } } } CartProduct cartProduct2 = new CartProduct { List<CartProductAttribute> d = new List<CartProductAttribute> { CartProductAttribute cpa3 = new CartProductAttribute{ title="john" }, CartProductAttribute cpa4 = new CartProductAttribute{ title="mary" } } } } } I would like to get from the Cart = a CartProduct that has the exact same CartProductAttribute title values as a CartProduct that I need to compare. No more and no less. E.G. I need to find a similar CartProduct that has a CartProductAttribute with title="red" and a cartProductAttribute with title="small" in myCart (eg 'cartProduct1' in the example) CartProduct cartProductToCompare = new CartProduct { List<CartProductAttribute> cartProductToCompareAttributes = new List<CartProductAttribute> { CartProductAttribute cpa5 = new CartProductAttribute{ title="red" }, CartProductAttribute cpa6 = new CartProductAttribute{ title="small" } } } So from object graph myCart cartProduct1 cpa1 (title=red) cpa2 (title=small) cartProduct2 cpa3 (title=john) cpa4 (title=mary) Linq query looking for cartProductToCompare cpa5 (title=red) cpa6 (title=small) Should find cartProduct1 Hope all this makes sense... Thanks

  • Informix, NHibernate, TransactionScope interaction difficulties

    - by John Prideaux
    I have a small program that is trying to wrap an NHibernate insert into an Informix database in a TransactionScope object using the Informix .NET Provider. I am getting the error specified below. The code without the TransactionScope object works -- including when the insert is wrapped in an NHibernate session transaction. Any ideas on what the problem is? BTW, without the EnterpriseServicesInterop, the Informix .NET Provider will not participate in a TransactionScope transaction (verified without NHibernate involved). Code Snippet: public static void TestTScope() { Employee johnp = new Employee { name = "John Prideaux" }; using (TransactionScope tscope = new TransactionScope( TransactionScopeOption.Required, new TransactionOptions() { Timeout = new TimeSpan(0, 1, 0), IsolationLevel = IsolationLevel.ReadCommitted }, EnterpriseServicesInteropOption.Full)) { using (ISession session = OpenSession()) { session.Save(johnp); Console.WriteLine("Saved John to the database"); } } Console.WriteLine("Transaction should be rolled back"); } static ISession OpenSession() { if (factory == null) { Configuration c = new Configuration(); c.AddAssembly(Assembly.GetCallingAssembly()); factory = c.BuildSessionFactory(); } return factory.OpenSession(); } static ISessionFactory factory; Stack Trace: NHibernate.ADOException was unhandled Message="Could not close IBM.Data.Informix.IfxConnection connection" Source="NHibernate" StackTrace: at NHibernate.Connection.ConnectionProvider.CloseConnection(IDbConnection conn) at NHibernate.Connection.DriverConnectionProvider.CloseConnection(IDbConnection conn) at NHibernate.Tool.hbm2ddl.SuppliedConnectionProviderConnectionHelper.Release() at NHibernate.Tool.hbm2ddl.SchemaMetadataUpdater.GetReservedWords(Dialect dialect, IConnectionHelper connectionHelper) at NHibernate.Tool.hbm2ddl.SchemaMetadataUpdater.Update(ISessionFactory sessionFactory) at NHibernate.Impl.SessionFactoryImpl..ctor(Configuration cfg, IMapping mapping, Settings settings, EventListeners listeners) at NHibernate.Cfg.Configuration.BuildSessionFactory() at HelloNHibernate.Employee.OpenSession() in D:\Development\ScratchProject\HelloNHibernate\Employee.cs:line 73 at HelloNHibernate.Employee.TestTScope() in D:\Development\ScratchProject\HelloNHibernate\Employee.cs:line 53 at HelloNHibernate.Program.Main(String[] args) in D:\Development\ScratchProject\HelloNHibernate\Program.cs:line 19 at System.AppDomain._nExecuteAssembly(Assembly assembly, String[] args) at System.AppDomain.ExecuteAssembly(String assemblyFile, Evidence assemblySecurity, String[] args) at Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly() at System.Threading.ThreadHelper.ThreadStart_Context(Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart() InnerException: IBM.Data.Informix.IfxException Message="ERROR - no error information available" Source="IBM.Data.Informix" ErrorCode=-2147467259 StackTrace: at IBM.Data.Informix.IfxConnection.HandleError(IntPtr hHandle, SQL_HANDLE hType, RETCODE retcode) at IBM.Data.Informix.IfxConnection.DisposeClose() at IBM.Data.Informix.IfxConnection.Close() at NHibernate.Connection.ConnectionProvider.CloseConnection(IDbConnection conn) InnerException:

  • User Productivity Kit - Powerful Packages (Part 2)

    - by [email protected]
    In my first post on packages I described what a package is and how it can be used. I also started explaining some of the considerations that should be taken into account when determining how to arrange your packages. The first is when the files are interrelated and depend on one another such as an HTML file and it's graphics. A second consideration is how the files are used in your outlines. Let's say you're using a dozen Word doc files. You could place them all in a single package or put each Word doc file in a separate package but what's the right thing to do? There are several factors that will influence your decision. To understand the first, let me explain a function of UPK publishing. Take an outline in UPK that has an attachment (concept, frame link, or hyperlink) that points to a file in a package. When you publish this outline, the publishing engine will determine that there is a link to a file in the package and copy the contents of the package to the publishing destination directory. This is done to ensure that any interrelated files are kept together. For the situation where you have an HTML file with links to number of graphics files, this is a good thing. If, however, the package has a dozen unrelated Word doc files and you link to only one of them, all dozen Word documents will be copied to the publishing destination directory.  Whether or not this is a good thing is dependent on two things. First, are all of the files in the package used in the outline that you're publishing? Take an outline that includes links to all of the Word documents in that dozen document package I described earlier. For this situation, you may choose to keep all the files in a single package for convenience. A second consideration is how your organization leverages reuse in UPK. In this context, I'm referring to the link style of reuse such as when you link to the same topic from multiple UPK outlines and changes to the topic appear in both places. Take an example where you have the earlier mentioned dozen Word document package and an outline with a dozen topics in it. Each topic has an attachment pointing to one of the Word documents in the package (frame link, concept, etc.) If you're only publishing this outline, the single package probably works fine but what if you're reusing one of these topics in another outline? As I explained earlier, linking to one file in the package will result in all files in the package being copied to your published output. In this example, linking to one topic in the first outline will result in all dozen Word documents being copied to the published output. This may result in files in the output that you don't want there for business or size reasons. This is a situation in which you should consider placing each of the Word documents in it's own separate package. With each document in it's own package, that link to a single document will result in only that single package and single Word document being copied to the published output. In my last post I had described that packages are documents in the UPK library. When using the multi-user version of the UPK Developer you can leverage standard library capabilities for managing the files in these packages during the development process - capabilities such as check in / check out, history, etc. When structuring your packages take into consideration how the authors are going to be adding, modifying and deleting files from the packages. A single package is a single document in the UPK library. Like any other document in the library, a single user can check out the package and edit it at a time. If you have a large number of files in a single package and these must be modified by many users, you need to consider whether this will cause problems as multiple users compete to update the same package. If the files don't depend on each other consider placing the files in separate packages to reduce contention. I hope you've enjoyed these two posts on how you can leverage the power of packages in your content. In summary, consider the following when structuring your packages: Is the asset a single, standalone file or a set of files that depend on each other? Will all the files always be used together in a single outline or may only some of the files be needed based on how the content is reused across multiple outlines? Will multiple developers need to update the files in a single package or should you break it into multiple packages to reduce contention when checking out the document? We'd like to hear from you on how you're using packages in your content. Please add your comments below! Thank you and I hope these two posts have given you additional insights into how to use packages in your content and structure them for efficient use.

  • Master database Compatibility level after an In-place Upgrade

    - by Jonathan Kehayias
    Yesterday a forums member asked why sys.dm_exec_sql_text() wouldn’t work on one instance of SQL where he was a sysadmin while the same code worked correctly on another instance of SQL.  The initial thought was that it was some kind of permissions issue.  Ken Simmons ( blog / twitter ) pointed out that the compatibility level of the database would affect the ability to use this DMF and that running it from a database at 80 compatibility would fail.  It turns out the person was running...(read more)

  • Global ignore pattern for TortoiseSVN / Visual Studio 2010

    - by Chris Simmons
    After installing and using Visual Studio 2010, I'm seeing some newer file types (at least with C++ projects ... don't know about the other types) as compared to 2008. e.g. .sdf, .opensdf, which I guess are the replacement for ncb files with Intellisense info stored in SQL Server Compact files? I also notice .log files are generated, which appear to be build logs. Given this, what's safe to add to my global ignore pattern? Off the bat, I'd assume .sdf, .opensdf, but what else?

  • LINQ into SortedList

    - by Chris Simmons
    I'm a complete LINQ newbie, so I don't know if my LINQ is incorrect for what I need to do or if my expectations of performance are too high. I've got a SortedList of objects, keyed by int; SortedList as opposed to SortedDictionary because I'll be populating the collection with pre-sorted data. My task is to find either the exact key or, if there is no exact key, the one with the next higher value. If the search is too high for the list (e.g. highest key is 100, but search for 105), return null. // The structure of this class is unimportant. Just using // it as an illustration. public class CX { public int KEY; public DateTime DT; } static CX getItem(int i, SortedList<int, CX> list) { var items = (from kv in list where kv.Key >= i select kv.Key); if (items.Any()) { return list[items.Min()]; } return null; } Given a list of 50,000 records, calling getItem 500 times takes about a second and a half. Calling it 50,000 times takes over 2 minutes. This performance seems very poor. Is my LINQ bad? Am I expecting too much? Should I be rolling my own binary search function?

  • running multi threads in Java

    - by owca
    My task is to simulate activity of couple of persons. Each of them has few activities to perform in some random time: fast (0-5s), medium(5-10s), slow(10-20s) and very slow(20-30s). Each person performs its task independently in the same time. At the beginning of new task I should print it's random time, start the task and then after time passes show next task's time and start it. I've written run() function that counts time, but now it looks like threads are done one after another and not in the same time or maybe they're just printed in this way. public class People{ public static void main(String[] args){ Task tasksA[]={new Task("washing","fast"), new Task("reading","slow"), new Task("shopping","medium")}; Task tasksM[]={new Task("sleeping zzzzzzzzzz","very slow"), new Task("learning","slow"), new Task(" :** ","slow"), new Task("passing an exam","slow") }; Task tasksJ[]={new Task("listening music","medium"), new Task("doing nothing","slow"), new Task("walking","medium") }; BusyPerson friends[]={ new BusyPerson("Alice",tasksA), new BusyPerson("Mark",tasksM), new BusyPerson("John",tasksJ)}; System.out.println("STARTING....................."); for(BusyPerson f: friends) (new Thread(f)).start(); System.out.println("DONE........................."); } } class Task { private String task; private int time; private Task[]tasks; public Task(String t, String s){ task = t; Speed speed = new Speed(); time = speed.getSpeed(s); } public Task(Task[]tab){ Task[]table=new Task[tab.length]; for(int i=0; i < tab.length; i++){ table[i] = tab[i]; } this.tasks = table; } } class Speed { private static String[]hows = {"fast","medium","slow","very slow"}; private static int[]maxs = {5000, 10000, 20000, 30000}; public Speed(){ } public static int getSpeed( String speedString){ String s = speedString; int up_limit=0; int down_limit=0; int time=0; //get limits of time for(int i=0; i<hows.length; i++){ if(s.equals(hows[i])){ up_limit = maxs[i]; if(i>0){ down_limit = maxs[i-1]; } else{ down_limit = 0; } } } //get random time within the limits Random rand = new Random(); time = rand.nextInt(up_limit) + down_limit; return time; } } class BusyPerson implements Runnable { private String name; private Task[] person_tasks; private BusyPerson[]persons; public BusyPerson(String s, Task[]t){ name = s; person_tasks = t; } public BusyPerson(BusyPerson[]tab){ BusyPerson[]table=new BusyPerson[tab.length]; for(int i=0; i < tab.length; i++){ table[i] = tab[i]; } this.persons = table; } public void run() { int time = 0; double t1=0; for(Task t: person_tasks){ t1 = (double)t.time/1000; System.out.println(name+" is...

  • Which Stroustrup book should I use?

    - by Chris Simmons
    I'm a C# programmer that is looking to branch out. I'm bored of writing business software and want to start getting into graphics programming and games/simulators. So I figured, although writing that stuff isn't impossible in managed code, the "right" way to do that would be to look to C++, of course focussing on the language first, then getting into OpenGL or DirectX (or whatever). Way way back ('98? '99?) I had tried and failed to really grasp Stroustrup's The C++ Programming Language. I know that this book is often not recommended for the beginner. Anyway, I picked it back up (in a much more recent printing) and I'm actually getting it and enjoying it. I also have a copy of his textbook, Programming: Principles and Practice Using C++, which, as I understand it, is really geared toward teaching programming, not necessarily C++. I'm certainly not arrogant enough to claim I don't have anything more to learn about programming, data structures, algoriths, etc., however I'm not a novice there either. So my question is, with the goal of gaining the broader and more real-world-useful understanding of C++ and given my background, on which should I focus? The denser (as I perceive it) TCPPPL or the gentler Programming? EDIT: I thank everyone for the responses. However, I've got a personal choice here to make between these two books. Granted there are other very good books out there, but I'm already a good length into both of the books I mention and I'd like to finish one. So, can anyone respond on which would be the better and why? Time is not an issue; I'm not looking (at this point) at an "accelerated" read.

    I have a query as follows: SELECT 1 FROM shop_inventory a JOIN shop_items b ON b.id=a.iid AND b.szbid=3362169 AND b.cid=a.cid WHERE a.cid=1 GROUP BY a.bought The only thing I need to do with this data is work out the number of rows returned (which I could do with mysqli -> num_rows;. However, I would like to know if there is a method to return the number of rows that match the query, without having to run num_rows? For example, the query should return one row, with one result, number_of_rows. I hope this makes sense!

  • UIScrollView Does not Scroll

    - by paul simmons
    I have added a long info screen to my iPhone app. The info is a long UIImageView, and it is contained inside a UIScrollView. They are both defined in .xib file. At run-time, initially I set scrollview's position outside window, and when user clicks a button, set its position inside window. This part is OK. But scrollview displays the image but does not scroll. Isn't it enough to place in MainViewContoller.xib, set the contained content, and (at code) set its contentSize equal to the content's size? BTW: I try it at simulator currently.

  • C Objects in Objective-C

    - by paul simmons
    Hi, I couldn't find a clear explanation, just asking to be sure; are C data types handled same way (in terms of memory management) in Obj.C? i.e. they are created on stack, released immediately etc.? So they differ from Obj.C objects? Or may we make an analogy with C# (just an analogy not exactly) so that C types are handled as 'value types' and Obj.C objects as 'reference types'?

  • iPhone Wait For Animation Ending

    - by paul simmons
    Hi, In an iPhone application, I try to catch animation endings using setAnimationDidStopSelector. I try to suspend code execution until animation ends. I have tried this; set a global BOOL variable, set it to TRUE before commiting animation and after commiting animations waited using a while loop. In the setAnimationDidStopSelector, set the BOOL variable to FALSE and hope while loop to break. But unluckily this did not work, the code did not even fall into setAnimationDidStopSelector (I check that with some trace outputs). What do you suggest?
