Good one!

I'll test it specifically, but I think the logic would be:
Since the source IP is matched in the Client Address Set, user
authentication is unnecessary, saving processing time

Since Tom said I had the hardest questions at Blackhat, I feel like I have
to ensure that they are all difficult ;)

To that end, I pose the following question:

Lets say you have a protocol rule to allow IP based on a client address set
(IP address), and another identical protocol rule that is based on
user/group.  If a user meets both criteria, i.e, is in the client address
set and is also a member of the group-based rule, which rule is used?
