[Samba] Exchange 5.5 on a Samba Domain

I recently migrated from an NT4 Domain to a Samba domain with LDAP 
backend. We use Exchange 5.5 on NT4 as our mail/groupware.
All existing users on the domain appear to be using the Exchange Server 
without any problems. However, when i create new users they cannot 
access their mail box'es from Outlook. The Event log on the Exchange 
Server reports the following error :

> A logon attempt failed because an attempt to look up Windows NT 
> account information failed. Error 1332.

The new user accounts appear to work perfectly otherwise. They can log 
onto the Domain and the Exchange NT4 Serve itself. They can even check 
their mail using squirrelmail webmail which connects to the exchange 
server using IMAP.
I sniffed the communication between the Exchange server and the Samba 
Domain server with ethereal and the only communication i can see is a 
couple of DCERPC packets.

Anyone had this problem before ?.
