Ok listen.

Once you login, your username is set in an enviroment variable (use the
"set" commands with no parms to see...).

That means that if you were logged in, and then the perms changed, and u
didn't log out before rebooting, that the problem might have been
earlier...

BUT, if you logged in, it was ok, logged out, rebooted, went into signle
user (if I understood you correctly) - and then rebooted again and the
problem started, I guess it's something in the init script of single
user initlevel.

If however that wasn't the situation, and you were logged before and can't
be sure when it started exactly.. look for script kiddies on your LAN, I
guess. :)
