Subject: [PATCH] This adds /useexisting to use current AFS creds, bypassing
 the initial authentication dialog box. It's useful if you're not running
 kaserver (i.e. if you've moved over to kerberos 5) and can't authenticate
 again by the normal AFS means.

(cherry picked from commit b0e4e7bcbfb911563f68cd91c21d905738123d72)
