I would believe this information is shared from the server to the other computers but here users still can connect (via SSH). If I try to get the information on the user connected I have: # chage -l USER user 'USER' does not exist in /etc/passwd
This looks normal as there is no user there but then I do not know how to enable the expiration information through NIS. Do someone has an idea?
You can't. NIS on linux does not support password aging.
If your using NIS then I would use Kerberos for the users passwords to maintain security. If your using Kerberos then I believe password aging is handled on the Kerberos server.
