The MSSQL server is used by an accounting program (Exact Globe 2000)

server decide if the user is allowed to make a connection.
For some reason this fails with the following error:
"Login failed for user '(null)'. Not associated with a trusted SQL
Isn't Samba able to do this? Should I upgrade to samba 3.0?
Thanks in advance,
