Actually, it happens automagically because suing without the dash shouldn't
change the $XAUTHORITY.

lufthans:~$ echo $XAUTHORITY
/tmp/ssh-XX6CVip2/cookies
lufthans:~$ su
Password: 
/home/lufthans# echo $XAUTHORITY
/tmp/ssh-XX6CVip2/cookies
/home/lufthans# 

This is a debian box at home, not the box with the prob. I checked
XAUTHORITY there. It was either the same or not set in both cases. It's now
the same as it was, but works.

It seems that the problem was due to a domain expiring, but the primary
server for it being the first server in resolv.conf. Changing the domain
fixed it. I don't like that answer. If it's broken, it should be broken for
everybody, dammit, not just root :). Unfortunately, I don't have time to
dedicate to testing it properly. Maybe later when I need a break from the
rest of the project.
