[Samba] Problems to authenticate Ubuntu 14 on Samba4

[Marcio Demetrio Bacci]

Hi,

I have saw many tutorials to ingress Ubuntu 14 in the Samba4 domain, but
none worked properly. I put the Ubuntu workstation in the Domain, but when
I try to login, appear the following messenge:

"your password will be expire in 42 days "

and does not permit the authentication.

How can I configure correctly Ubuntu 14 workstation to authenticate in the
Samba 4 domain?


Thanks
