I'm running 1.6L from January 4.  I know there are some issues with 
permissions since /tmp and /var/spool/output/lpd were set wrong.

su asks for a password, notes that kerberos doesn't apply, and just 
says Sorry.  I don't see anything in the logs except a reject message.

I have my user listed in /etc/group in the wheel group.
