• Active directory authentication for Ubuntu Linux login and cifs mounting home directories...

  - by Jamie

  I've configured my Ubuntu 10.04 Server LTS Beta 2 residing on a windows network to authenticate logins using active directory, then mount a windows share to serve as there home directory. Here is what I did starting from the initial installation of Ubuntu. Download and install Ubuntu Server 10.04 LTS Beta 2 Get updates # sudo apt-get update && sudo apt-get upgrade Install an SSH server (sshd) # sudo apt-get install openssh-server Some would argue that you should "lock sshd down" by disabling root logins. I figure if your smart enough to hack an ssh session for a root password, you're probably not going to be thwarted by the addition of PermitRootLogin no in the /etc/ssh/sshd_config file. If your paranoid or not simply not convinced then edit the file or give the following a spin: # (grep PermitRootLogin /etc/ssh/sshd_conifg && sudo sed -ri 's/PermitRootLogin ).+/\1no/' /etc/ssh/sshd_conifg) || echo "PermitRootLogin not found. Add it manually." Install required packages # sudo apt-get install winbind samba smbfs smbclient ntp krb5-user Do some basic networking housecleaning in preparation for the specific package configurations to come. Determine your windows domain name, DNS server name, and IP address for the active directory server (for samba). For conveniance I set environment variables for the windows domain and DNS server. For me it was (my AD IP address was 192.168.20.11): # WINDOMAIN=mydomain.local && WINDNS=srv1.$WINDOMAIN If you want to figure out what your domain and DNS server is (I was contractor and didn't know the network) check out this helpful reference. The authentication and file sharing processes for the Windows and Linux boxes need to have their clocks agree. Do this with an NTP service, and on the server version of Ubuntu the NTP service comes installed and preconfigured. The network I was joining had the DNS server serving up the NTP service too. # sudo sed -ri "s/^(server[ \t]).+/\1$WINDNS/" /etc/ntp.conf Restart the NTP daemon # sudo /etc/init.d/ntp restart We need to christen the Linux box on the new network, this is done by editing the host file (replace the DNS of with the FQDN of the windows DNS): # sudo sed -ri "s/^(127\.0\.0\.1[ \t]).*/\1$(hostname).$WINDOMAIN localhost $(hostname)/" /etc/hosts Kerberos configuration. The instructions that follow here aren't to be taken literally: the values for MYDOMAIN.LOCAL and srv1.mydomain.local need to be replaced with what's appropriate for your network when you edit the files. Edit the (previously installed above) /etc/krb5.conf file. Find the [libdefaults] section and change (or add) the key value pair (and it is in UPPERCASE WHERE IT NEEDS TO BE): [libdefaults] default_realm = MYDOMAIN.LOCAL Add the following to the [realms] section of the file: MYDOMAIN.LOCAL = { kdc = srv1.mydomain.local admin_server = srv1.mydomain.local default_domain = MYDOMAIN.LOCAL } Add the following to the [domain_realm] section of the file: .mydomain.local = MYDOMAIN.LOCAL mydomain.local = MYDOMAIN.LOCAL Conmfigure samba. When it's all said done, I don't know where SAMBA fits in ... I used cifs to mount the windows shares ... regardless, my system works and this is how I did it. Replace /etc/samba/smb.conf (remember I was working from a clean distro of Ubuntu, so I wasn't worried about breaking anything): [global] security = ads realm = MYDOMAIN.LOCAL password server = 192.168.20.11 workgroup = MYDOMAIN idmap uid = 10000-20000 idmap gid = 10000-20000 winbind enum users = yes winbind enum groups = yes template homedir = /home/%D/%U template shell = /bin/bash client use spnego = yes client ntlmv2 auth = yes encrypt passwords = yes winbind use default domain = yes restrict anonymous = 2 Start and stop various services. # sudo /etc/init.d/winbind stop # sudo service smbd restart # sudo /etc/init.d/winbind start Setup the authentication. Edit the /etc/nsswitch.conf. Here are the contents of mine: passwd: compat winbind group: compat winbind shadow: compat winbind hosts: files dns networks: files protocols: db files services: db files ethers: db files rpc: db files Start and stop various services. # sudo /etc/init.d/winbind stop # sudo service smbd restart # sudo /etc/init.d/winbind start At this point I could login, home directories didn't exist, but I could login. Later I'll come back and add how I got the cifs automounting to work. Numerous resources were considered so I could figure this out. Here is a short list (a number of these links point to mine own questions on the topic): Samba Kerberos Active Directory WinBind Mounting Linux user home directories on CIFS server Authenticating OpenBSD against Active Directory How to use Active Directory to authenticate linux users Mounting windows shares with Active Directory permissions Using Active Directory authentication with Samba on Ubuntu 9.10 server 64bit How practical is to authenticate a Linux server against AD?

• WCF "DataContext accessed after Dispose"

  - by David Ward

  I have an application with numerous WCF services that make use of LINQ-To-SQL as the data access model. I am having lots of problems with the "DataContext accessed after Dispose" exception. I understand what this exception is and that it is occurring because I have not "initialised" the data that is trying to be accessed. I've read many articles that suggest that I called ToList() on any arrays before the parent object is returned by the service. My issue is that I am getting this exception and I don't know where it is originating from and therefore I don't know what hasn't been initialised. Can anyone advise how best to identify the root cause? (I have used the MS Service Trace Viewer and this doesn't seem to give me any further information)

• SSIS Configuration error: Cannot retrieve configuration table schema

  - by Glenn M

  I'm trying to add a simple configuration to a SSIS package, of type SQL Server, so stored in a table. At the end of the wizard, when it goes to try and write a new row to the nominated table to store the configuration it fails with the error: TITLE: Microsoft Visual Studio Could not complete wizard actions. Cannot retrieve configuration table schema. (Microsoft.DataTransformationServices.Wizards) I can't seem to resolve this. The configuration connection has full permissions on the table, and it sees it and can read from it as it reports there is no current data for the filter I provide. It just wont write to it. A Google search of the error message above in quotes returns literally no hits! Any suggestions? Glenn

• Sync database with filter using SyncOrchestrator with Sync Framework 2.0

  - by Flo

  Hi, I want to synchronize two SQL databases. But since one of the databases only requires a subset of the data I am looking for a filter option. Is there a possibility to add a Filter to the SyncOrchestrator or do I have to add the filter to the SyncProvider? According to this: http://social.microsoft.com/Forums/en-US/uklaunch2007ado.net/thread/35d4deb8-a861-4fe3-a395-d175e14c353f it is not possible to filter with the DbSyncProvider. Quote: "I understand your scenario, and the hebavior of the DbSyncProvider is due to the current limitation. DbSyncProvider is built on top of the Microsoft Sync Framework that can support filtering. Unfortunately, DbSyncProvider does not yet." But that post is quite old, maybe that has changed now. I am working with this example at the moment: http://msdn.microsoft.com/en-us/library/cc807255.aspx but I can't figure out how to add filtering here.

• Compiled Linq & String.Contains

  - by sharru

  i'm using linq-to-sql and i'm use complied linq for better performance. I have a users table with a INT field called "LookingFor" that can have the following values.1,2,3,12,123,13,23. I wrote a query to return the users based on the "lookingFor" column i want to return all users that contains the "lookingFor" value (not only those equal to it). In example if user.LookingFor = 12 , and query paramter is 1 this user should be selected. private static Func<NeDataContext, int, IQueryable<int>> MainSearchQuery = CompiledQuery.Compile((NeDataContext db, int lookingFor) => (from u in db.Users where (lookingFor == -1 ? true : u.LookingFor.ToString().Contains(lookingFor) select u.username); This WORKS on non complied linq but throws error when using complied. How do i fix it to work using complied linq? I get this error: Only arguments that can be evaluated on the client are supported for the String.Contains method.

• Embed SQL Password into Crystal Reports RPT file?

  - by codeulike

  We are experimenting with Crystal Reports viewers such as this one: http://www.thereportviewer.com/ ... which can actually re-connect to the data source and re-run a Crystal Reports RPT file with live data. However when running the report the viewer asks for a password to connect to the data source (in this case SQL Server). Does Crystal Reports have some way of embedding a connection password into a RPT file to avoid this? Or should I be using a System DSN from the Control Panel/ODBC thing to get around this? I figure someone else must have had this problem.

• Method 'SingleOrDefault' not supported by Linq to Entities

  - by user300992

  I read other posts on similar problem on using SingleOfDefault on Linq-To-Entity, some suggested using "First()" and some others suggested using "Extension" method to implement the Single(). This code throws exception: Movie movie = (from a in movies where a.MovieID == '12345' select a).SingleOrDefault(); If I convert the object query to a List using .ToList(), "SingleOrDefault()" actually works perfectly without throwing any error. My question is: Is it not good to convert to List? Is it going to be performance issue for more complicated queries? What does it get translated in SQL? Movie movie = (from a in movies.ToList() where a.MovieID == '12345' select a).SingleOrDefault();

• Why does select SCOPE_IDENTITY() return a decimal instead of an integer?

  - by Earlz

  So I have a table with an identity column as the primary key, so it is an integer. So, why does SCOPE_IDENTITY() always return a decimal value instead of an int to my C# application? This is really annoying since decimal values will not implicitly convert to integers in C#, which means I now have to rewrite a bunch of stuff and have a lot of helper methods because I use SQL Server and Postgres, which Postgres does return an integer for the equivalent function.. Why does SCOPE_IDENTITY() not just return a plain integer? Are there people out there that commonly use decimal/non-identity values for primary keys?

• Linq to Entities : using ToLower() on NText fields

  - by Julien N

  I'm using SQL Server 2005, with a case sensitive database.. In a search function, I need to create a Linq To Entities (L2E) query with a "where" clause that compare several strings with the data in the database with these rules : The comparison is a "Contains" mode, not strict compare : easy as the string's Contains() method is allowed in L2E The comparison must be case insensitive : I use ToLower() on both elements to perform an insensitive comparison. All of this performs really well but I ran into the following Exception : "Argument data type ntext is invalid for argument 1 of lower function" on one of my fields. It seems that the field is a NText field and I can't perform a ToLower() on that. What could I do to be able to perform a case insensitive Contains() on that NText field ?

• Multiple JOIN and SELECT Statements from eight tables

  - by user1486004

  I am trying to make an SQL statement that takes eight different numbers and searches eight different tables from one database for the corresponding value. I keep getting invalid syntax, but I can't figure out why. Here is my code: SELECT cable_length.ID, drawing.ID, optional.ID, output_type.ID, pressure_range.ID, pressure_type.ID, series.ID, termination.ID FROM ( SELECT value AS cable_length FROM A1 WHERE A1.id = %s JOIN SELECT value AS drawing FROM A2 WHERE A2.id = %s, JOIN SELECT value AS optional FROM A3 WHERE A3.id = %s, JOIN SELECT value AS output_type FROM A4 WHERE A4.id = %s, JOIN SELECT value AS pressure_range FROM A5 WHERE A5.id = %s, JOIN SELECT value AS pressure_type FROM A6 WHERE A6.id = %s, JOIN SELECT value AS series FROM A7 WHERE A7.id = %s, JOIN SELECT value AS termination FROM A8 WHERE A8.id = %s ); The %s will be changed to numbers only. The column name in each database is "ID" and "Value". I want to search by "ID" and return "Value". Any help is greatly appreciated.

• MySql - Get row number on select

  - by George

  Can I run a select statement and get the row number if the items are sorted? I have a table like this: mysql> describe orders; +-------------+---------------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +-------------+---------------------+------+-----+---------+----------------+ | orderID | bigint(20) unsigned | NO | PRI | NULL | auto_increment | | itemID | bigint(20) unsigned | NO | | NULL | | +-------------+---------------------+------+-----+---------+----------------+ I can then run this query to get the number of orders by ID: SELECT itemID, COUNT(*) as ordercount FROM orders GROUP BY itemID ORDER BY ordercount DESC; This gives me a count of each itemID in the table like this: +--------+------------+ | itemID | ordercount | +--------+------------+ | 388 | 3 | | 234 | 2 | | 3432 | 1 | | 693 | 1 | | 3459 | 1 | +--------+------------+ I want to get the row number as well, so I could tell that itemID 388 is the first row, 234 is second, etc (essentially the ranking of the orders, not just a raw count). I know I can do this in java when I get the result set back, but I was wondering if there was a way to handle it purely in SQL.

• MySQL query returns different set of results on two identical databases

  - by 1nsane

  I exported a live MySQL database (running mysql 5.0.45) to a local copy (running mysql 5.1.33) with no errors upon import. There is a view in the database, that when executed locally, returns a different set of data than when executed remotely. It's returning 32 results instead of 63. When I execute the raw sql, the same problem occurs. I've inspected the data in all tables being joined, and the counts are the same. The query is simple and has no where conditions - but about 10 joins. Aside from the differences in mysql versions... I can't find any reason that this query would return different results between databases... since they are effectively exact copies. Has anyone experienced a problem like this before?

• Any alternative to Sybase Sql Advantage?

  - by eKek0

  Sybase Sql Advantage is the default editor for the Sybase database. But it has lots of shortcomings, because it basically is what Notepad is for Windows users: Can't do multiple undo's Monochrome, text is black and background is white Can't see what character did you exactly paste from clipboard, and sometimes this lead to weirdness behaviour Don't see what line or column you are in the moment Lack of funcionality like exports to different formats, integration with source control, plugins, etc. I have to deal with this editor in my daily work, so I was wondering if there are any other tool. Do you know any replacement?

• System.Security.VerificationException: Operation could destabilize the runtime

  - by Rigobert Song

  I have a web service which is queried using linq to sql but returns an array of objects. I keep getting the following error: System.Security.VerificationException: Operation could destabilize the runtime When I run a method that uses a linq statement to return an array I get this error, but only on my test server, which is windows server 2008. Everything works fine in my win 7 machine. The project is a .net 3.5. Any ideas what the problem might be? Thanks UPDATE: My linq queries return IQueryable.

• Merge\Combine two datatables

  - by madlan

  I'm trying to merge\combine two datatables. I've looked at various examples and answers but they seem to create duplicate rows or require indexes (merge on datatable etc) I can't do this via SQL as one source is from a linked Oracle server accessed via MSSQL and the other from a different MSSQL Server that does not have linked access. The data is currently very simple: Name, Email, Phone DataTable1: "John Clark", "", "01522 55231" "Alex King", "[email protected]", "01522 55266" "Marcus Jones", "[email protected]", "01522 55461" DataTable2: "John Clark", "[email protected]", "01522 55231" "Alex King", "[email protected]", "" "Marcus Jones", "[email protected]", "01522 55461" "Warren bean", "[email protected]", "01522 522311" Giving a datatable with the following: "John Clark", "[email protected]", "01522 55231" "Alex King", "[email protected]", "01522 55266" "Marcus Jones", "[email protected]", "01522 55461" "Warren bean", "[email protected]", "01522 522311" Name is the field to match records on, with the first datatable taking priority.

• Good embedded database solution (like SQLite) for .Net

  - by vfilby

  I am looking for file based storage solutions that I can use with a .Net project. THey need to have a sql-like interface for storing and retrieving data. They need to have relatively little overhead and must not require any additional components installed by the end user. I am hopping for a .dll that I can reference and use. Cool points awarded if it is closely tied to an ORM. My current favourite is SQLite, are there any better ones out there that I should know about? I have a (health?) bias against access because I feel it is overcomplicated for what I need, I am open to being convinced otherwise though. PS: "No, there is nothing better than SQLite" is a perfectly good answer.

• TransactionScope and Connection Pooling

  - by Graham

  Hi, I'm trying to get a handle on whether we have a problem in our application with database connections using incorrect IsolationLevels. Our application is a .Net 3.5 database app using SQL Server 2005. I've discovered that the IsolationLevel of connections are not reset when they are returned to the connection pool (see here) and was also really surprised to read in this blog post that each new TransactionScope created gets its own connection pool assigned to it. Our database updates (via our business objects) take place within a TransactionScope (a new one is created for each business object graph update). But our fetches do not use an explicit transaction. So what I'm wondering is could we ever get into the situation where our fetch operations (which should be using the default IsolationLevel - Read Committed) would reuse a connection from the pool which has been used for an update, and inherit the update IsolationLevel (RepeatableRead)? Or would our updates be guaranteed to use a different connection pool seeing as they are wrapped in a TransactionScope? Thanks in advance, Graham

• Load Balancing using SQL Server and TempData MVC

  - by Jamie

  Hi all, I've been told that MVC 1.0 TempData does not work under a load balancer when using SQL Server and that it is because the Dictionary itself is not serializable. We require this for a project and are looking to be able load balancer effectively. So I would be very grateful if someone could answer the following questions: Is there away around this so you can make it work? Is this fixed in MVC 2.0? Can we create a ITempDataProvider to fix it? Or has anyone made a fix to the source code for a project of their own they would like to share? Cheers, Jamie

  I have select: select v.accs, v.currency,v.amount,v.drcr_ind, count(*) qua,wm_concat(ids) npx_IDS, wm_concat(px_dtct) npx_DTCT from table v group by accs, currency, amount, drcr_ind but i get error ORA-06502: PL/SQL: : character string buffer too small if i'll remove one string, because sometimes (when v.accs= 3570) count(*) = 215 but when i try to skip using wm_concat for v.accs= 3570 for example this way: select v.accs, v.currency,v.amount,v.drcr_ind, count(*) qua,wm_concat(ids) npx_IDS, (case when v.accs = 3570 then wm_concat(px_dtct) else 'too many' end) npx_DTCT from table v group by accs, currency, amount, drcr_ind i still have the same error message. But why? How can i fix it? Thanx
