samba - Sep 2004 - Can't join Domain on PDC: NT_STATUS_CANT_ACCESS_DOMAIN_INFO (PAM: 4)

Hi all,

I've got the following problem when trying to join a domain on a samba pdc
itself:

net rpc join eccag -U root

asks for password an then tells me that it cannot connect to the PDC.
Winbind-log gives the following:

[2004/08/31 02:29:15, 0] nsswitch/winbindd_util.c:get_trust_pw(1024)
  get_trust_pw: could not fetch trust account password for my domain ECCAG
[2004/08/31 02:29:15, 2] nsswitch/winbindd_pam.c:winbindd_pam_auth_crap(612)
  NTLM CRAP authentication for user [ECCAG]\[] returned
NT_STATUS_CANT_ACCESS_DOMAIN_INFO (PAM: 4)
[2004/08/31 02:29:15, 5] nsswitch/winbindd.c:winbind_client_read(465)
  read failed on sock 20, pid 13841: EOF

Can anyone help me?

kind regards,
Michael
