samba - Apr 2004 - Error make_server_info_info3: pdb_init_sam failed!

Hi,

Samba 3.0.1 on Solaris 9.

We have a user domain EMEA and a resource domain NLRESOURCES.

[global]
	workgroup = NLRESOURCES
	security = DOMAIN
	password server = nlresod01,nlresod02

All users in the EMEA domain can access the shares without any problems.

Except for one user. This user cannot access any of the shares.
>From the log file:
[2004/04/06 11:23:33, 0] auth/auth_util.c:make_server_info_info3(1080)
  make_server_info_info3: pdb_init_sam failed!

As far as I can tell all users have the same settings.

Any idea what could be the problem?

Thanks,

Simon.
