Erro de Senha Incorreta ou Usuário Desconhecido ao tentar ingressar no Dominio com Samba como DC

Bom dia Prezados,

Estou com um problema em que o cenário é o seguinte:

Servidor DC: Debian 8.2 com samba

Ip: 192.168.5.1

do lado do servidor, todos os comandos retornam ok:

root@debsrv:/home/freitas# host -t A debsrv.freitas.com.br.

debsrv.freitas.com.br has address 192.168.5.1

root@debsrv:/home/freitas# host -t SRV _kerberos._udp.freitas.com.br.

_kerberos._udp.freitas.com.br has SRV record 0 100 88 debsrv.freitas.com.br.

root@debsrv:/home/freitas# host -t SRV _ldap._tcp.freitas.com.br.

_ldap._tcp.freitas.com.br has SRV record 0 100 389 debsrv.freitas.com.br.

root@debsrv:/home/freitas# netstat -tapn | grep smbd

debsrv.freitas.com.br

root@debsrv:/home/freitas# cat /etc/resolv.conf

search debsrv.freitas.com.br home

nameserver 192.168.5.1

nameserver 192.168.25.1

Cliente: Windows 7 Sp1

Ao tentar ingressar no dominio, ele gera um erro de usuário desconhecido ou senha incorreta.

Porém o nltest retorna tudo ok:

nltest /dsgetdc:freitas

O windows pinga normalmente o servidor.
