Comment 5 for bug 33727

If you add your nis user to the admin group in etc /etc/group then it works. (At least for me.) I added the nis user(s) to all groups the initial user was added. I have seen a bug report that it dose not work with the admin group over the network, I can nither confirm nor deny that case. With local system groups and remote users it works.

On a side note I keep the initial user as administrator in case of network failure. That is way safer than using the real root.
