[Samba] Possible big/small endian problem Samba 2.2.2 and 2.2.3a

[PRETORIUS, Albert]

Hi 

We are running Samba on an IBM zSeries mainframe on Linux kernel 2.2.16 and
are running
into problems when using winbindd and security=domain. We are doing a proof
of concept using
opensource and I really hope we can pull it off!
Before I raise a bug report, I would appreciate it if someone can tell me if
this is a known
problem. I have not found anything on it yet.

We have winbindd set up have 'security = domain' coded and use encrypted
passwords.

When client authenticates, we get the following error in the logs of Samba
(loglevel=9)

smbd/password.c:connect_to_domain_password_server
connect_to_domain_password_server: unable to setup the PDC credentials to
machine NTPDC.
Error was : NT_STATUS_ACCESS_DENIED.

If I look at   smbd/password.c   connect_to_domain_password_server routine,
it seems as we fail
on the very last call:

  if (!NT_STATUS_IS_OK(cli_nt_setup_creds(pcli, trust_passwd))) {
    DEBUG(0,("connect_to_domain_password_server: unable to setup the PDC
credentials to machine \
%s. Error was : %s.\n", remote_machine, cli_errstr(pcli)));
    cli_nt_session_close(pcli);
    cli_ulogoff(pcli);
    cli_shutdown(pcli);
    return(False);
  }

I have about exhausted all possible things to try. Also, this works 100% on
a Intel based PC with Samba 2.2.3a.
We compared the smb.conf files between the mainframe Linux and the PC Linux
and the only thing I currently
suspect is a big/small endian problem (mainframe uses big-endian and intel
uses small-endian).

Any help much appreciated.
thanks
