UIDS < 0?

[holland () engg ksu edu (Rich Holland)]

At LISA VIII, someone in the Automounter BOF brought up the fact (I
don't recall why) that under AIX, if your 'nobody' userid was greater
than 65-thousand-something, it would wrap (due to the limitation of a
longint uid field and 32-bit userids).  This didn't seem like a big deal,
except that they also said that by having negative userids, there were
big security holes opened up.  Anyone know what these are?  I've been
playing with a nobody with a uid of 70000, and haven't found anything...
