I just installed BM3.8 in my office after upgrading the network from
SBS6 to SBS6.5. One key feature I'm looking for is Access rules to
limit internet access based on user id.

When I set up a rule to allow HTTP Proxy access for any user, I have
internet access. When I change that rule to only permit access for
myself, two other managers and Admin, I receive the warning that my
access is prohibited.

Any suggestions are appreciated. I'm new to 3.8, but I've been a
long-time user of BM. Admin has definitely changed...
