That was the original design, however I was told that this is not
something people will be interested in. Thanks for you data point but to
change it we probably need couple more data points and comments.

This will really be a relieve not to support it for now.

The problem is that it is reverse.
Since for IPA the host groups are primary concepts and the netgroup is
something we want to phase out the logic is the following:
* Hosts are grouped into the host groups.
* A netgroup is a shallow container around the host group.
In our model host group can be a member of the netgroup not vice versa.
But this is not related to the question at hand.

The question regarding memberUser is that the sudo spec allows using a
netgroup to refer to a set of users. This is really a atavism to use
netgroups to reference a set of users instead of a direct user group.
The question is: can we assume it to be an atavism and not support it.
I updated the page so this point is more clear.

Yes this is number vs. string question.

Thank you for the comment. I think the only missing point is about
"negating the whole rule" instead of per command.
Do you agree that it would be more manageable as proposed?
