Ok, finally on the weekend I upgraded the system without big issues. 
When the system was upgraded it was serving all services, including 
Samba and authentication.

First of all... everything was backed up... twice, diferent medias.

Two situations after upgrade:

1. Every user had to reset password in first login authentication to domain.

2. Once the password was reset, unexpected, the system notified users 
that password had expired. With the command

# pdbedit -P "maximum password age"

I saw that it had the  "180" value (seconds), so I had to change this 
policy with the command:

# pdbedit -P "maximum password age" -C -1

Wich means, never expire the password. I need this policy this way.

Well.. good luck to any body who need to work with this.

Thank you for your advices.
