What Is Trusted_Connection?

Jan 13, 2005

I have been using an Access DB until now and am going to start looking at using an SQL Server instead. My first task was to make sure that I could connect. I created a basic DB and created and added a user as public, datareader and datawriter.

My first attempt at a connection string was -"server=local;uid=someuser;pwd=password;database=basic"and it couldn't find the server (I tried 'localhost' as well).

My next attempt was -"server=QTLAP01;User ID=someuser;pwd=password;database=basic"And I got the error "Reason: Not associated with a trusted SQL Server connection.".

I eventually found that the following worked -"server=QTLAP01;User ID=someuser;pwd=password;database=basic;Trusted_Connection=true"But, I don't understand why. Why would it believe that the connection was trusted just because I said it was?

Thanks
Martin

PS the computer in question is not connected to a network so no problems with username and password security.

Trusted_connection=true, Login '(null)'

Mar 31, 2006

When accessing a web application from an intranet....
And the web app tries to make a connection to a 'SQL Server' using the sqlconnection where does ASP.NET grab user credentials?
My webpage displays web security.principal.windows.getcurrent = domainUser  (displays the correct information).
But the connection to sql says Null.  Where is ASP.NET grabbing (retrieving) this information from?
Thanks,

ODBC Trusted_Connection Call To SQLGetInfo Returns DBO As User Name, Not NT User

Sep 26, 2004

Hello, all:
I am connecting to SQL Server 2000 with a trusted connection, and that is working fine. I then am issuing a SQLGetInfo call to find out the SQL_USER_NAME, which is always returning dbo instead of (my) Windows NT login name, which I expect to see. THe authentication is (apparently) confirmed by the SQL Server session monitor where it shows the right Windows NT user name logged in, over ODBC. With a standard SQL Login, untrusted, I definitely get the right user name back, not dbo.

So:

Login Type / user id /returned value from SQLGetInfo

Windows Authentication / Windows login / dbo
SQL Authentication / Windows login (UID) / UID

The problem is that I am trying to confirm that the userid entered in a dialog or passed on the command line to my application matches the actual connected user name inside SQL Server....


My questions:
Is there some pathology in Trusted_Connections that masks the Windows/NT login name and always returns UID 'dbo' from a call to SQLGetInfo? Is there a MSS (public) stored procedure that can robustly give back the logged in user name so I can bypass the SQLGetInfo call?
