Messenger 2.0.3 on netware 6.5sp6

I had a user DaveS : I had to change his name to DavidS and after that his messenger stopped working (back in January). He logs into the novell client and to groupwise fine since the change with the new username and password, but messenger rejects him saying invalid username or password. The messaging agent console says SPL login failed [0xAD0B] davids - invalid credentials supplied to ldap.

So I recreated the user object thinking it must be corrupt. Am still getting the same error. I did not restart messenger after I recreated him - which I never typically do when I create new users.

Any ideas are appreciated as he has decided he now wants to start using messenger again.
