Linux kerberos authentication ; gdm

[Nicolas Michel]

Hi here,

I want to authenticate some linux computers (ubuntu) on a kerberos
server, linked to an ldap one. I see how to do that with pam.
But I have two questions :
- is there an "offline" mode? (if I have no access to the internet I
want to have access to my session)
- with gdm, is it possible to get a window when the password must be
changed (and where must I configure that password policy? On the
kerberos server?)

Thank you very much
