I want to set up Active Directory authentication for my users, who will be assigned to specific database roles. I also need to log activity and ensure I have captured the IDs of the indivudals connected.

I have found simple instructions on how to do it. ( How do I assign an entire Active Directory group security access in SQL Server 2008? )

... But Will SYSTEM_USER return the logon id of the active directory connection or the individual user? (Unfortunately I cannot test this!)

What is getuserid()? – Derek Kromm Jul 16 '12 at 16:14
There is no built-in getuserid() function in SQL. Are you talking about the GETUSERID() function available in Report Builder (for Reporting Services)? – squillman Jul 16 '12 at 16:16
Sorry, My Bad - I meant SYSTEM_USER – littlebobbytables Jul 16 '12 at 16:36

A call to system_user will return the AD user's name in your case. For instance, if you have a user set up as YourDomain\YourUser1:

select system_user

-- this returns "YourDomain\YourUser1"

If YourDomain\YourUser1 is part of a AD group (i.e. YourDomain\YourGroup1), then it would still have the same output as above (returning "YourDomain\YourUser1").

Jon - I didn't spot the link you posted earlier. No reference to AD but a good reference to know about, thanks. – littlebobbytables Jul 17 '12 at 8:28
