Hello,

I'm using MIT Kerberos and trying to figure out how to make tickets
have a more reasonable default lifetime.  So far, I have tried
editing /etc/krb5.conf on both the client and the server, however, I
still get a TGT which lasts only 10 hours.  I'd like the ticket to be
issued for 7 days, and be renewable for up to 21 days.  Is there a way
to do this?

Also, is there a way to detect when the ticket is no longer renewable
and prompt the user to logout, perhaps?  My setup is Kerberos tied into
PAM, using LDAP for user information, and NFSv4 for home directories,
and it's all Ubuntu (Intrepid, if that helps).
