I€™m working on an application that needs to support multiple users without log in and out of Windows. I would like to use trusted/integrated security (domainusername) so I.T. does not have to manage two accounts per operator. Is it possible to use trusted accounts (domainusername) in the SQLClient.Connection object?
Thanks!

We are looking at developing an SQL Server 2005 Database and I would like to use Windows Authentication rather than SQL Server Authentication to connect our client app.
In our development environment, we have two Servers, one being used as a file server and the other as an SQL Server. We have now set up a domain using the file server as the domain controller. (We had previously been set up to use a workgroup).
I have set up an active directory group called SqlDevelopers and added an active directory user called Jonathan to it.
On the SQL Sever, in management studio, I have set up a new server login which uses windows authentication called DomainSqlDevelopers. I used the GUI to verify I could see the domain and the group.
The default database is set to a test database on the server. A user in the test database is mapped to the DomainSqlDevelopers and given the Roles dbo, db_datareader, db_datawriter.
To test the log in, on the server, I logged out as administrator and in as Jonathan. I could successfully access the server through management studio using windows authentication.
However, if I log in as Jonathan on my client PC and try to access the SQL Server using management studio and windows authentication, I have problems.
The first time I try I will get a timeout error. If I try again will get either:
Login failed for user ''. The user is not associated with a trusted SQL Server connection
Or
Cannot generate SSPI context
I can€™t determine any pattern to which of the above errors I get.
However, if I log in as administrator on my client PC, I can connect to the server using management studio and windows authentication.
Sounds like Active Directory/Domain or other Network issue (Not really my area). I would be grateful for any help.
Thanks,
Jon
Hi all.
M trying to create a logon form
I had something in mind but i can work it out yet
When the user wants to login into the application the value of textbox must be compared with the datafield in the sql server.
And then i want a messagebox to show up.
I created a table in sql server with 2 fields in it , User and Password.
I hope anyone could help me tnx already
Hi. I have a DetailsView with Bound Fields "Login" and "Password". This informations are stored in SQL database. How to solve such authorization? How to compare password stored in database against passowrd typed by user? Is this a good idea to use CustomValidator control to write some checking procedure?. Regards. Pawel.
View 1 Replies View RelatedI am a systems analyst and work with an app that runs against 2 SQL Server DBs. Though I have some familiarity with SQL Server and SQL, I am not a DBA.
The app executable is tied to a Windows service.
When we install the app, we run a process that builds 2 dbs to include:
Tables, indexes, stored procedures, views and user accounts.
SQL Server is set up for mixed mode authentication.
Normally, the dbs run off the local db user accounts which are tied to local logins with the same names.
We have a client that wants to remove our standard logins so that they can run on only a Windows login.
I know I should be able to tie the db users to a Windows login.
And I can do the same for the service.
But I am at a loss as to how to get this done.
How do you associate db users with a Windows login?
When I have tried sp_change_users_login I get an error that the Windows login does not exist. (Though I have added the Windows account to the DB.)
Hope this all makes sense.
I can not connect to my Local SQL Server 2005 in C# code,
it throws the error,
The user is not associated with a trusted SQL Server connection.
i tried to change the mode to Mixed Mode, but i don't see it, I see only Windows and SQL Server Auth mode,
i tried to change to SQL Server Mode, but none of user log will work, it says, this login is not in trusted connection,
so i would make any login associated with trusted account.
Thanks,
We have a local group the consists of users from a trusted domain.. THis is a one way trust, us trusting them.. When I add that local group as a trusted SQL login the users cannot access the database... We have narrowed it down to the security by verifying the user can log in using a test sql account and hit the database.. Any ideas??? IS it possible to map an account to a Local group on the domain or does it have to be a global group????
Thanks in Advance

We have a SQL 2000 Active/Passive cluster running on Windows 2000. On one node, everything logs in fine (second node is powered off). I can use local authentication fine in OSQL (-E) and even see my connection in SQLEM current activity as [DomainUser] for the NT account which I am logged in as. Then I bring the second node online and initiate a failover. SQL Server starts but Cluster Admin cannot connect and starts throwing this Anonymous Logon error. I open a command prompt and try the same OSQL (-E) local login and sure enough it is also giving the Anonymous Logon connection user. I do not understand why the failover to a second node is causing the Trusted Connection Local authentication to switch to Anonymous instead of the [DomainUser] which I am using. Any help is appreciated. John.
View 1 Replies View RelatedI'm getting Not associated with a trusted SQL Server connectionerrors on a .Net windows service I wrote, when it's running on myapplication server.It's not a problem with mixed mode security. I'm set for mixed mode andI've been running the service on the app server for over a month withno problem. My database is running on a second server and both areunder the same domain.The problem has occurred twice over the last two months.The windows service queries a table every 30 seconds, looking forrecords to process.

Butwhen I start it up on the application server, I get the 'notassociated' error back from Sql Server.I'm trying to figure out where the problem is, and why it'sintermittent. Is it rights, policy, security? Why does it work for awhile then then error out?Any suggestions or help is appreciated.Thanks,Eric

One of my users gets the following error when he tries to connect to my SQL Server 2000 database using windows authentication via Query Analyzer:
[Micorsoft][ODBC SQL Server Driver][SQL Server] Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
Me and the server are located in Colorado and are on the NADomain. User is in London on the EURDomain. The EURDomain has a one way trust to the NADomain to use NADomain resources. I have granted access to the database to the user via Enterpise Manager as EURDomainuserid. All the literature I've read says this should be sufficient to connect but isn't. User can connect with SQL Server authentication. Users on the NADomain in Toronto can connect just fine with Windows Authentication. EURDomain user can access other file server resources in the same building as the SQL Server in Colorado.
SQL Server version is:
Microsoft SQL Server 2000 - 8.00.818 (Intel X86) Standard Edition on Windows NT 5.0 (Build 2195: Service Pack 4)
EURDomain Client ODBC version is 2000.85.1022.00 and MDAC is 2.8.

Hi Eeveryone!
I am using SQL server 2000 with Webmatrix to build a simple Asp.net app, but facing this problem:
Using Entrprise Manager, I have created a login name "ASPNET" and gave it access as db_owner to the default database "master" , but still could not open SQL connection from Webmatrix aspx file!
The error message I get is :
Login failed for user "ASPNET". Reason : Not associated with as trusterd SQL Server .
I truely apprciate your help!
Some remote users can't login to the database-server
with a trusted connection.
There's an error message indicating that the domain,
which is the same for all users, is missing.
In the EventLog we can see the successful logon in
the security view (this time with domain) and the
failed logon to SQL Server (without domain) in the
SQL Server log.
We also managed to change default domain for SQL Server
reported in xp_login_config through editing in the registry-
settings. There are no other way to do it in SQL Server 7.0.
But this doesn't help us.

Andre Ekespong
HI,
I've got the folloing scenario:
Client app is a windows forms app on client machine. Web Service on a dev machine (Windows 2003 standard), SQL Server 2000 on a seperate machine. The user logs on to the using their windows login. I'd like to pass these credentials to the web service, have the web service impersonate the user and access the SQL Server with these credentials... not a problem I thought.
Setup windows integrated login on IIS for the web service, impersonate="true" in the web.config, Mixed mode on the SQL server. Passed the network credentials through to the Web Service, and this works correctly, however when the web service (impersonating the user) tries to access the SQL Server, I get the message about access denied, user is null, blah, blah. (if remote access the Web Service box, and call the web service locally, all works well, and voila, until the thread recycles, the client machine access also works... same user/pass)..
I've seen various posts about this but nothing seems to solve the problem. Am I right in thinking that this method (Windows integrated login) of passing credentials through to the SQL Server is the best method? If so... er, shouldn't it work? What am I doing wrong here? and if it doesn't work, what other method would work?
I've just about given up on this and thinking of passing the SQL Server Username/Password across the network (shudder), encrypted yes, but not ideal!
Anyone got any idea?
Regards
Kevin

All,
In Microsoft analysis services, I get an error that login fails for user "NULL" when I try to process/build any cubes. If I edit the connection properties, it says to use "trusted" signon. If I press the "test connection" button all is well.
I definitely have serverdatabase access otherwise. Any thoughts/insights?

ps: this is a sql server 2000 version of MSAS. Corresponding sql server is 2000 as well.
I have 2 (XP Pro) machines -- each with its own instance of 2005 Express. I wrote a simple test in C# to access a few global vars such as @@VERSION.
When I run the test on 1 machine it works fine, but on the other machine it fails with the message: login failed for user sa, not a trusted connection. Both instances of Express have mixed mode authentication enabled & remote connections enabled.
If I add Integrated Security=true to the connection string, the test works on both machines. I believe this forces the connection to authenticate using Windows instead of SQL Server.
I have created a new user & password in Express, but the results are the same: 1 machine works & 1 fails.
The machine that fails is missing the following from the list of logins:
AIRSTREAMSQLServer2005MSFTEUser$AIRSTREAM$SQLEXPRESS
In fact, after poking around, I can see the problem with just the 2005 Management Console. Cannot access the 1 machine with SQL authentication using either of 2 users -- just in case I got 1 wrong.
Any help will be appreciated. I've run out of any good ideas.
TIA,
Joe
Hey. I've a script which gets the SQL usernames with the information I need. Is it possible to migrate the passwords also with this information?
Also, regarding Windows Logins, do i have to worry about their SIDS when migrating to SQL 2005. I'm going to attach SQL 2000 db's onto a 2005SQL instance and these db's alreayd have the usernames assigned in them. Please let me know if there is a way out for the above two questions. thank you.
SELECT 'Create LOGIN [' + loginname + '] with password = ''hello'', sid = ',sid,

I set up SQL Express and Visual Studio Team System for the first time yesterday. I created a web service (on my localhost IIS) and added an MDF file to my App_Data folder. I added a table with five fields. I'm trying to connect to the database in my web service, but when my web service gets to the connection line it returns the error
System.Data.SqlClient.SqlException: Login failed for user ''. The user is not associated with a trusted SQL Server connection.
When I add in my domain name and password to the connection string I get the error
System.Data.SqlClient.SqlException: Login failed for user 'redmonddanmor'. The user is not associated with a trusted SQL Server connection.
I've queried these SQL forums, and the advice is usually "add the user to the trusted users" or "changed to mixed mode authentication", but none of the posts I found specified HOW exactly to do either. When I launch SQL Server Connection Manager all I can appear to do is stop and start the service. I'm not sure what needs to be set for SQLEXPRESS properties to log on as Network Service, Local System, or Local Service.

Attempting to implement Windows authentication between trusted domains. . .
I have a domain trust set up between two domains connected via persistent vpn:
I connected successfully in SQL Server Management studio using the 'sa' login and changed the authentication mode to Windows NT because I could not connect using my windows login but now I can't get any connection at all because 'sa' is no longer trusted.
I changed the loginmode registry setting to 2 and rebooted my PC but this has made no difference.
Can anyone help me get the 'sa' login back?
Hello All,
Login failed for user '(null)'.
I know this issue is all over the forum, however i have not found any posts that help me resolve the issue.
Situation:
I have an ASP.NET 2.0 application hosted currently on XP pro(will be moving to 2003 Server) which connects to a SQL 2000 database that resides on a different server. I have taken the following step to implement my security.
Given my account permissions to the database
Put the following in my web.config
<add name="MyName" connectionString="Data Source=MyServer;Initial Catalog=MyDatabase;Integrated Security=SSPI" providerName="System.Data.SqlClient" />
<authentication mode="Windows" />
<identity impersonate ="true" />
I have set IIS to use integrated authentication and removed anonymous. The application works when run from the web server but not when run from a remote machine.
Thank you for any asistance,

1. Create a Domain Account with priveleges similar NETWORKSERVICE (windows server 2003).2. Grant this Domain Account (DomainName/NETWORKSERVICE ) access in the SQL Server Database for the necessary databases (created a new login for this user and gave it the privillage creator, read, write)3. <identity impersonate="true" userName="DomainNameUserName" password="password" />The second method is to simply set identity impersonate to true and assign the username and password in the IIS.1. Type inetmgr from your command prompt and give enter.2. This would open the IIS Control Panel.3. Expand the appropriate nodes and select the Virtual Directory of your application.4. Right Click and select Properties.5. Switch to the Directory Security Tab.6. Under Anonymous access and authentication control click Edit7. Check the Enable Anonymous access in case you want people to access the application without logging in with Windows Logon Screen.8.
