   Xlogin should only attempt to destroy kerberos tickets upon logout if
   it created kerberos tickets automatically upon login.

   For example, when I log in as root, xlogin shouldn't be trying to
   destroy tickets when I log out.  But it is, or at least so it would
   appear from the "No tickets to destroy" message that is displayed
   right after I type "logout".

I would disagree... From a security point of view, I think it should
destroy anything in the KRBTKFILE that login would normally set.  The
user could have easily forgotten about acquired tickets.  In fact, our
other login programs (ie. /bin/login) also destroy tickets, regardless
of whether it obtained them initially (and actually, I sometimes forget
to type kdestroy, and thank the fact that login deals for me).
