SQL Server Windows Auth For ETL Called By CreateProcessAsUser

May 11, 2007

Hi,

We are having problems in our project. We have ETL packages we call from our web app that we want to run and the user is the logged in one in the web.

We use Windows Authentication in our web app and we used the CreateProcessAsUser to impersonate the user. <identity impersonate="true"/> is also in our web.config.

We were able to call the dtexec successfully (with the user for the process as the logged in the web -- thus impersonation was successful.)

But, a problem arises when we use Windows Authentication for the connection of the ETL to the db (SQL Server). When we run the ETL on our local machine using dtexec/dtexecui, it works fine.

But when we ran it in our server, it fails. According to the event logs, it can't connect to the db server even though impersonation is successful.

Btw, the client, web server, db server are three different machines.

Any help is appreciated. Thanks!

How To Change Windows Auth. To SQL Server Auth. In SSIS Packages

Apr 30, 2007

I had a few packages created with Windows Authentication which now needs to be migrated to run with SQL Server Authentication. I tried changing it in the connection managers but the packages failed to validate at the SCD transformations.For a few packages I had Configuration files for these packages where i tried to do it but it dint run giving the following Error Message:
[Connection manager "Target"] Error: An OLE DB error has occurred. Error code: 0x80040E4D. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E4D Description: "Login failed for user <<with my network id>>.".

[Execute SQL Task] Error: Failed to acquire connection "Target". Connection may not be configured correctly or you may not have the right permissions on this connection.

Target was the name of my connection.

SQL Server 7 Switches To Windows Only Auth On Reboot

Jul 20, 2005

Hi All,I have a SQL Server 7 installation running on a windows 2000 server.SQL Server switches from mixed mode authentication to Windows Only onreboot. Has anyone else experienced this?

Connecting To SQL Server 2005 Using Windows Auth/Cannot Generate SSPI Context Error

Jan 3, 2008

Hi-I have a program that I am developing on a laptop, then deploying it on a server.I have the prgram running passing a username and PW in the connection object, but like the idea of using windows authentication MUCH better.I just joined the domain, so I am domain/me for example.If I log into the server, and look at securities, logins and added domain/me to the logins.I then try and set up a sql connection via both visual studio, and sql server magt studio, and get the dreaded "Cannot generate SSPI context" error. Anyone else have this problem? SHOULD V.S. be using domain/me to connect?  TIA dan

We have always used sql servwer login to the servers for all our applications for out intranet apps

And we use windows auth to do development

So when we do that we logon to wuindows, and then just connect, with no password required

But how does an application "logon" to connect to a database

Is it just in the connection string just like sql server auth

or is it different?

Clean Install Windows Auth Error

Feb 17, 2007

Hi,

I cannot log in to SQL Server 2005 Dev Edition in my local machine using Windows Authentication. The server returned "Login failed..." when connecting with SQL Server Management Studio.

I have not change anything since installation of this server.

This problem happens in RTM and SP1 versions, both running on Windows Vista RTM.

Anyone having this kind of problem too? Any solution? I'm guessing it's Vista-related.

Is there any way to provide 'Windows' credentials to connect the Management Studio to a remote SQL 2000 DB when I am not logged on as that user (on the dev machine where I am running Mgmt Studio)?

I do of course have local machine admin rights via an AD domain account added to the machine administrators on the remote SQL box itself.

Get Windows Logged In Username In SQL When Using Win Auth Mode In SQL Form ASP

Jun 18, 2007

Hi Guys,
I have an Intranet web application and I have to use windows authentication. They are 4 main users group to access the application, each with different set of permission on my store procedures.
I have created a windows group for each of those group in my windows environemnt. My DB Connection String in web.config is set to Integrated Windows Authentication ( Integrated Security=SSPI)
I have done all configuration based on this article: http://msdn2.microsoft.com/en-us/library/ms998292.aspx
I have 4 different database Roles in my database and 4 different database users. I also add NT AUTHORITYNETWORK SERVICE as a member of each of those database Roles.
Now I get connected, fine and set permission on the database roles.
1 thing I want to know, How Can I get the Windows Group name in the database, which has the same name as my SQL Login and Database Roles or User
I tried all SUSER_SNAME() and ... they all return NT AUTHORITYNETWORK SERVICE
I want to get AppPowerUser Role or windows group name. I think I should be able to because I am using windows authentication.
Any help is appreciated.

CreateProcessAsUser In SQLCLR

May 15, 2006

I'll keep trying new threads here... sooner or later, I'm sure an expert Microsoft CLR employee will gladly lend a helping hand!

The pieces:

1. SQL 2005, MS Windows Server 2003, Standard Edition, SP 1

2. .NET 2005/C#

3. Instance of SQL 2005 running locally.

Trigger on local SQL2005 DB table INSERT calls 2 CLR Functions:

1. Retrieve data from SQL2005 DB table and populate local DBF through OLEDB

2. Call external 16-bit application (written in Clipper) that iterates through local DBF records (added from step 1 above) and populates DBF on domain resource.

Step 2 detail:

External 16-bit application is called by CreateProcessAsUser after impersonating token.

THIS IS SUCCESSFUL - IF: I populate SQL2005 DB table using TSQL insert statement. The trigger executes, Step 1 and Step 2 execute perfectly!

THIS IS UNSUCCESSFUL - IF: The SQL2005 DB table is populated by synchronizing SQL Mobile Server database from a SQL Mobile Edition 2005 PDA emulation. The trigger executes. Step 1 executes perfectly. Step 2 executes without exceptions. HOWEVER, the 16-bit application does not execute! Remember, no exceptions. In fact, the result variable returns true from function below:

result = ProcessUtility.CreateProcessAsUser(

hDupedToken,

null,

@"C:MobileDBMobile.exe",

ref sa, ref sa,

false, 0, IntPtr.Zero,

@"C:MobileDB", ref si, ref pi

);

Also, if I Right-click on the Step 2 function in the Server Explorer and click "Execute", it works perfectly. Domain DBF is updated successfully.

So, in short CLR "CreateProcessAsUser" is not doing it's job when the trigger is fired after SQL 2005 DB is populated via replication/sychronization. I would appreciate a response... Thx!

Xpsql.cpp: Error 1314 From CreateProcessAsUser On Line 636

Jan 4, 2005

Hi,

I want to give a non system administrator account permission to execute xp_cmdshell.

I'm testing it by running this:

xp_cmdshell 'dir c:'

and getting this error

Msg 50001, Level 1, State 50001
xpsql.cpp: Error 1314 from CreateProcessAsUser on line 636

I have a setup a proxy account in SQL Server Agent as instructed - it's the same account that the SQL Server Service is running under.

I've deselected the 'only users with sysadm privilages...' option in SQL Server Agent properties and I've tried granting a variety of permissions to the proxy account based suggestions I've seen on google. It's a domain account which has local admin rights.

Other people seem to have found solutions but none of them have worked for me - any siggestions? SQL Server 2k Std Edn and Windows 2003 Server Std Edn.

Thanks,

Longhorn Server, WSSv3, SQL Express 2005 And Forms Auth Setup Issue

Jun 6, 2007

I seem to be having a strange problem with accessing the SQL Express database under the following configuration.



Install Longhorn Server Beta 2
Add WSS role, setup default site, everything seems to be working fine (using NTLM auth for the site). Content database clearly working fine to the embedded SQL Server Express.
Want to switch to Forms Based Authentication with SQL Membership Provider. Follow insructions for it and discover the following issues accessing the database:

aspnet_regsql (running locally on same box) fails and says it can't connect to the database
try using the surface area configuration tools to enable remote access/ protocols etc.
aspnet_regsql still fails and says it can't connect to the database
Install the SQL Management Studio Express - try connecting it to the databse to explore the tables etc.
SQL Management Studio Express fails to connect to the database
Try switching client config to connect via shared memory rather than over TCP/IP etc.
Still fails to connect to database
Try install a third party tool called MSSQL Maestro (does some similar things to SQL Management Express)
Lo and behold - MSSQL Maestro connects to the database just fine, can explore the tables etc. No problems.
Try aspnet_regsql again, try SQL management express again after doing lots of things (try restarts etc. restarts of services). No luck.

So I'm confused. WSS seems to connect to the SQL Express config database fine. MSSQL Maestro connects to the database fine and will allow me to explore it. Using the exact same host and database name (the WSS configured default) aspnet_regsql and SQL Management Studio express both fail with the exact same error.



EDIT: Some significant additional details:

- I have two databases .MICROSOFT#SSEE (which is the WSS default internal database) and .SQLEXPRESS (installed when I installed the rest of SQL Express to get the management tools etc.)

- I can connect to them both by command line with sqlcmd -S.MICROSOFT#SSEE and sqlcmd -S.SQLEXPRESS just fine. They're both running.

- I CAN connect to.SQLEXPRESS from SQL Management Express Studio, but I cannot connect to .MICROSOFT#SSEE

- A look at the error log, shows a line like the following about listening on the named pipe for SQLEXPRESS database, but I don't see a similar entry for the MICROSOFT#SSEE (even thought it's configured to do so in configuration manager...)

"Server local connection provider is ready to accept connection on [ \.pipeSQLLocalSQLEXPRESS ]."

- I've run SQL Management Express as administrator - no change

- The error I get is either error 26, or error 40 when using Shared Memory protocol

- I get the same error and error code from aspnet_regsql



Any suggestions? I'm stumped...

Does SQL Server Check For Constraint Violation When COMMIT Is Called?

Oct 27, 2007

If there are two different transactions, both of which update the username column to 'xyz' for userid = 234 in 'Users' table. This is a unique value for username.  Ater this update each transaction adds a row to 'AppLog' table. The transaction is only committed after second operation.
The 'username' column has a unique constraint on it.
If transaction isolation level is 'read committed', and both transaction execute the first operation when neither of the transactions have been committed, then the transaction that calls COMMIT later will error out or not? If COMMIT does not check constraints then it will NOT error out. As a result we will have a violation of unique constraint happening without any error being thrown by SQL Server.

SQL Server 2008 :: WAITFOR Being Ignored In Stored Proc Only When Called From EF

We're trying to troubleshoot a timeout issue, so it was requested that I add a WAITFOR statement (1 hour) in a certain stored proc our application uses. I added it and confirmed that it was working by executing the stored proc in SSMS.

However, when our application (using Entity Framework) calls the stored proc, the WAITFOR statement is ignored.

SQL Server 2012 :: Duplicate Of Part Num To Be Summed And Add Another Column Called User

Aug 25, 2015

There are 3 columns in the result set - part num, Qty and MO num. Each MO num has part numbers.So there might be same part numbers in MO's. Each part num has qty. So, if I group by part num, I get Qty.

1.There are duplicates of part.num and I want to remove duplicates and add quantities of those duplicates into one single quantity. For example, xxxx is a part num, then xxxx=1,xxxx=3,xxxx=5. I want xxxx=9. I want to sum those. Another question is, each MO has a user. I want to join user and MO num in MO.

Heres the code,

part.num , (woitem.qtytarget/wo.qtytarget) AS woitemqty,

(SELECT LIST(wo.num, ',') FROM wo INNER JOIN moitem ON wo.moitemid = moitem.id WHERE moitem.moid = mo.id) AS wonums FROM mo INNER JOIN moitem ON mo.id = moitem.moid

LEFT JOIN wo ON moitem.id = wo.moitemid

LEFT JOIN woitem ON wo.id = woitem.woid AND woitem.typeid = 10 LEFT JOIN (Select sum(woitem.qtytarget) as labor, woitem.woid, uom.code as uom from woitem JOIN part on woitem.partid = part.id and part.typeid = 21 JOIN uom on woitem.uomid = uom.id group by 2,3) as labor on wo.id = labor.woid LEFT JOIN part ON woitem.partid = part.id

Weird SQL Auth Error

Jun 20, 2006

hey all, i have a weird authentication error.i have two servers, both running sql server 2005. one is on my workstation the other is on my dev server. i backed up my workstation database and restored it on the dev server. my workstation is xp and my server win2k3. i'm developing an asp.net 2.0 app that talks to my sql server using windows auth. on my workstation my website runs under the ASPNET account, IUSER_COMPUTERNAME and i had that account setup in sql on my workstation in the main security folder, then again in the db security folder the name of it was [ASPNET LOGIN]. each sproc had EXEC permission for [ASPNET LOGIN].when i restored it over to my win2k3 box i deleted that login from the database and revoked it on all the sprocs. i then setup another account for the application and set my website to use that account. i couldn't use the original account because of the group it was in, blah blah blah, not important.  the thing is, i got rid of all instances of that ASPNET LOGIN account and i'm running the website under a new account, and some of the stored procedures work, but some of them i get the error "Cannot find the user 'ASPNET LOGIN', because it does not exist or you do not have permission." which is crazy, because i've gotten rid of all references to that. it's not anywhere i see in the database, not in either security/users folder, it's not on any of the stored procedures. and it's NOWHERE in the website. not in IIS or code. furthermore some of the stored procedures work. as far as i can tell, the ones that are not called from my custom MemberShipProvider are working. so i went back to my database on my workstation, revoked exec permission on the sprocs, deleted the login from the db and then from the sql server instance, backed it up again, restored on my server and i'm still getting this issue.where can that ASPNET LOGIN be hiding? i restarted too thinking maybe it was cached somewhere. this is my connection string that the entire app uses: "Server=[serverName]; Database=[dbName]; Trusted_Connection=true;"my web.config is using <identity impersonate="true"/> and my website is running under the account i created.any ideas? i've been battling this for half a day.and why would it only happen with the membership provider? it's using the same connection string the rest of the app is.

Integrated Auth And SQL Servers

Apr 4, 2005

I'm building a reporting server that will grab data off of a an old HP3000, all of that is being done in a background task (non asp.net) and uploaded to an sql server.
I'm using a web interface to allow people within the company to view the data.  This will be in a single domain, behind a firewall, and will not be accessable from outside of the company.
In IIS, I have anonymous login unchecked and only Integrated Windows Auth checked.  The pertinate parts of my web.config look like this:
<authentication mode="Windows" />
<identity impersonate="true" />
<authorization>
<allow users="*" />
<deny users="?" />
</authorization>
My connection string looks like this:
public static string SqlServerConnect = "Integrated Security=SSPI;Initial Catalog=[name of database];Data Source=[sqlserver IP]";
The website (for now) is on my local development computer.  When I run the program everything works fine, when I attempt to view the web page on another computer, I get the following error
Server Error in '/reports' Application.
Login failed for user 'NT AUTHORITYANONYMOUS LOGON'.
I'm at a loss as to how to fix this.  I dont really want each user to have to enter any log in information, frankly, the permissions dont even matter in this case.  My main problem is with the sql connection and trying to get adequate permissions to run queries.
Any help would be apprieciated

NT Auth - Setup Group?

Sep 19, 2007

Usually, we set up a SQL login for an applucation to use.
On this occasion, the connection is being done through NT authentication.
I am having to set up a login for each DOMAINuser.

Is there a better way of doing this maybe a logn for a group and add the users to the group?

I assumed SQL login was the preferred way as if you designed an app for thousands of users, you would have a large amount of administration if everything was done through NT ?

How To Tell If User Has Exec Auth On Sproc

Feb 6, 2008

And no, not through EM or SSMS

I want to interogate the catalog, so I can hae a job execute and do the grants in case a developer forgets

I mean I guess I can do the all everytime, but I don't know what the impact would be. It appears to be none, because of already done that, but in DB2 that would be bad as it would keep adding rows to the system tables

I have this so far


select *
from syspermissions p
inner join sysusers u
on u.uid = p.grantee
inner join sysobjects o
on o.id = p.id
where u.name = 'mepuser'
and o.name not like 'dt_%'

Auth Problem To SQL In Web Administration Tool

Apr 30, 2008

I am trying to set up the web administration for a website that uses login controls. I have set up the ASPNETDB database using the regular aspnet_regsql command on my SQLEXPRESS.




To set up the web admin tool, I created a vdir to point to %WINDIR%Microsoft.NETFrameworkv2.0.50727ASP.NETWebAdminFiles. This works absolutely fine. I also changed the configuration of this website to use the ASPNETDB on my SQLEXPRESS.

<add name="LocalSqlServer" connectionString="data source=.SQLEXPRESS;Integrated Security=SSPI;Initial Catalog=aspnetdb"
providerName="System.Data.SqlClient" />




This website also has impersonation enabled

<identity impersonate = "true" />




The administration website works fine till I click on the security tab, and I get the following error:

Cannot open database "aspnetdb" requested by the login. The login failed. Login failed for user 'HOMEASPNET'

What I don't understand is why the application is using the ASPNET account to connect to the database when impersonation is enabled. Isn't it supposed to use the credentials of the windows user? I read a couple of posts on MSDN which advise to explicitly create a login for the ASPNET user in the ASPNETDB database (which will definitely work) but somehow it seems counter-intuitive to me. Any advise anyone?

SQL7/SQL2000 Replication. Auth Error

Aug 12, 2002

I'm attemting to replicate from a SQL7 box to SQL2000.

The snapshot works fine, but it fails when it tries to push the subscription to the SQL2000 box with a trust error (I don't recall the exact message). I noticed that it fails when Enterprise Mgr is configured as: "Tools/Replication/Configure Publishing, Subscribers and Distribution", Subscriber Tab, "Impersonating SQL Service Agent". It works if I change to "SA".

This is only the case when we replicate from SQL7 to SQL2K. SQL7 to SQL7 works fine with "Impersonating". Has anybody seen this behavior? Any workarounds, other than using SA?

Aug 12, 2002

I'm attemting to replicate from a SQL7 box to SQL2000.

The snapshot works fine, but it fails when it tries to push the subscription to the SQL2000 box with a trust error (I don't recall the exact message). I noticed that it fails when Enterprise Mgr is configured as: "Tools/Replication/Configure Publishing, Subscribers and Distribution", Subscriber Tab, "Impersonating SQL Service Agent". It works if I change to "SA".

This is only the case when we replicate from SQL7 to SQL2K. SQL7 to SQL7 works fine with "Impersonating". Has anybody seen this behavior? Any workarounds, other than using SA?
