Unable to connect to the domain controller

[Niall Gormley]

When I attempt to change the NT workgroup as per the instructions in the NTDOM FAQ I get the error message : "Unabe to  connect to the domain controller for this domain. Have your administrator check you computer account on the domain. "

I have added the machine accounts to the /etc/passwd and the
/etc/smbpasswd and tested user authentication. I've also reset the password for the machine account a number of times.

The smb.conf file security setting is domain.

A relevant extract from  log.MACHINE is shown below.

  session_trust_account: Trust account ASC5$ only supported with
security = user
[1999/05/15 16:49:58, 3] smbd/error.c:error_packet(127)

Why should the trust account only be supported with security = user?

Can anyone shed some light on this for me.
In addition the SID seems to be called MACHINE.SID rather than
