the keyring being owned by uid 0 means that setpag() was called by
someone running as uid 0. the afs pag is always uid = 0 so that users
cant modify the key and discern its contents.
not owning the keyring used to be a problem with earlier version of
the keyring code as i recall. this explains the 'extra' permission
i dont know what created the _uid.0 keyring.
