samba - Apr 2005 - samba as BDC and getting this error NT_STATUS_NO_SUCH_USER

hey,

I am getting this error after configuring samba.I have configure samba
as BDC to a Win 2003 Domain Controller.I have created the same users
as they are on Windows 2003 on my samba server ,now whenever any user
clicks on the samba server it sees its home directories and other
folders.There is no user who is getting problem,but I am not able to
understand why I am getting this error.

domain_client_validate: unable to validate password for user Owner in
domain SUNUPDELHI to Domain controller \\SERVER1. Error was
NT_STATUS_NO_SUCH_USER


Thanks & Regards
