I am trying to grant permissions to a Windows 2000 group "TEST" (not builtin
group), this group can access the Database "myDatabase". The user "user1" is
a member of the group "TEST".

But I can not login in the Database with the user "user1" (when the user1 is
the active windows user).

Where is the problem?
