Wbinfo -u and -g com problemas

Galera estou com o seguinte problema.

Preciso interligar meu squid com um outro servidor linux que roda samba para pegar seus usuários e senhas.

Qdo digito getent passwd recebo blz todos os usuários do domínio.

Acontece que qdo digito:
wbinfo -u
Error looking up domain users

wbinfo -g
BUILTIN\system operators
BUILTIN\replicators
BUILTIN\guests
BUILTIN\power users
BUILTIN\print operators
BUILTIN\administrators
BUILTIN\account operators
BUILTIN\backup operators
BUILTIN\users

Não me retornando os grupos e usuários.

Ainda... qdo digito

server:~ # wbinfo -t
checking the trust secret via RPC calls succeeded

server:~ # wbinfo -a VITO\\fabio.henrique%senha
plaintext password authentication succeeded
challenge/response password authentication succeeded

Analisando /var/log/smb/log.winbind tenho

[2006/03/16 10:33:40, 1] nsswitch/winbindd_user.c:winbindd_getpwnam(161)
user 'imappublic' does not exist
[2006/03/16 10:33:40, 1] nsswitch/winbindd_user.c:winbindd_getpwnam(161)
user 'imapshared' does not exist

Será que alguém pode me ajudar?!

Segue o smb.conf
