Hi Again,
Some further information to add.
My samba PDC is running RHEL4 with samba version 3.0.10 (red hat rpm) 
and OpenLDAP 2.2.13.
Exchange 5.5 SP4 Build 2653.23 on NT4 SP6.
I have created the Domain user accounts with usrmgr.exe and the smbldap 
tools with the same results.
The samba domain is working apart from 1 other problem, adding computer 
accounts to the domain. When i attempt to add a PC to the domain from 
windows only a posix account is created in the directory. Creating the 
computer account with the smbldap tools works fine though so i am using 
this as a workaround for the moment.
Thanks,
Ian
