From 7e5d7dfa834c0161460bde8a2f0d4824c0a0d1fe Mon Sep 17 00:00:00 2001

Subject: Enable net ads commands to use existing tickets if the user doesn't
 specify a username on the commandline.  Also don't continue past the kinit if
 a password is entered and fails because existing tickets would be used, which
 may not be desired if the username was specified.
