security = domain, doesn't want to work

[robg at uws.edu.au]

I am setting up samba to authenticate to a PDC. With "security = server"
this works just fine. But It won't work when I try domain level security.

I have successfully joined the domain, and changed the workgoup parameter
to the domains netbios name.

But users can nolonger authenticate.

The log files give the following error message
[2001/11/21 15:34:20, 0] smbd/password.c:domain_client_validate(1554)
  domain_client_validate: could not fetch trust account password for
domain W2K-BLK-LAB

Any advice?

Thanks,
Rob.
