[Samba] Authentication Failure in member server

[Diego Alencar Alves de Lima]

I have a samba server configured that is member of a samba domain called=20
PRODESAN.COM.BR. After we had to reinstall the domain controller some samba=
=20
shares stopped working on the member server. I get this when I try to use t=
he=20
share:

However when I try to use the same user on the domain controller things wor=
k=20
perfectly:

[pr907899] succeeded

I can see the domain users using wbinfo -u on the member server and I have=
=20
(re)joined the domain using net rpc join:

net rpc join -U root
Password:
Joined domain PRODESAN.COM.BR.

Any ideas why the server isn't being able to authenticate the user?
