We have DB2 on a server using Windows Server 2003 Version 5.2(Build 3790.srv03_rtm.030324-2048) and DB2 Version 8.1.5.449

I have set up GROUPS in a database. These groups have also been created in Active Directory. A new userid was added to AD and when I try to log on to the database I get error SQL30082N with reason-code 24.

This is the error message from the DB2 manual.

Attempt to establish connection failed with security reason reason-code ( reason-string ).

24 (USERNAME AND/OR PASSWORD INVALID)
The username specified, password specified, or both, are invalid.

The userid and the password are both valid. Why can't DB2 recognize this userid?
