poff script problem

[Jude DaShiell <jdashiel@shellworld.net>]

If a user account is added to the dip group that user on reboot can use 
pon dsl-provider.  That same user though cannot use poff dsl-provider, it 
has to be used by root.  I just found this out so those using roaring 
penguin with dsl connections may want to take notice.  Probably a good 
workaround for this would be to add the same user to /etc/shutdown.allow.
