If we can't tell the kernel about all the groups a user is
member of, it can become a security problem if we continue
if your file system happens to have negative ACLs. So we
just stop. It *is* a problem in 3.0.30, because spurious
access denied errors might happen that should not. It is
just not as obvious.
