The only thing I was able to use it for was to provoke a system crash.

I tried to do a ``setauth -g devel'' after having created a `devel' group. 
`setauth' asked me for a password -- what password does it want me to type

Running a plain ``setauth'' without any command line arguments made it
iterate through all processes (I suppose), displaying either ``setauth:
[pid]: Operation not permitted'' or ``setauth: [pid]: Cannot get auth port:
(ipc/send) invalid destination port''.  The latter ones are the ids of
processes that don't even exist anymore, as a comparison with ``ps -Af''
could tell me.

After that I was left with no ids:

$ ids
effective uids: 
effective gids: 
available uids: 
available gids: 

Running ``setauth -g devel'' again made the system crash.  (I can't reproduce
this at the moment, however.)
