[Samba] LDAP user search request includes domain

[Howard Allison]

Hi,
I'm running a Samba 3.0.32 server on AIX 6.1, AIX is authorizing with 
secldapclntd to an OpenLDAP Server.
The Clients are coming from a Windows 2003 Terminal Server Thin Client 
session, logged in to the domain.
I see in the logs that secldapclntd tries 3 times to authorize using 
DOMAIN\USER as identification, and then finally uses USER(which works). 
Is this Samba behavior, or AIX? Is there any way to convince Samba that 
he should use just the User name for File Access?
Thanks
