We use ISA as just a caching proxy and that will authenticate against
the AD. I'm pretty positive that SQUID will also authenticate against AD
and comes in Linux and Windows flavours these days... Wingate is also a
good cheap proxy with AD integration. I would imagine that the
NetAppliance will 2 as it's not rocket science... You'll need to check.

You wouldn't need to authenticate all users... You would just put the
users you wish to have access into an AD group, i.e. 'Internet Users'
and then grant that group access through your proxy. The proxy would
then be the box which determines if a user can browse, etc.

I prefer the above methods for ease of management with standard
browsing.. It also improves browsing speeds due to the cache.

What are you using to maintain the user names, are you authenticating
against AD?

I wanted to avoid having to have everyone authenticate when only a few
will be blocked.

>>Session auth? Or put in an authenticating proxy and allow that access

I have to agree here.  We use surfcontrol to block by MAC address., but
that is a pain to manage.  Often PC's get upgraded, and the NIC that
once belonged to Joe Web Offender goes to innocent Jane, leaving Joe
with internet access and Jane without.

And if the PC/NIC is retired, then how would you know to update
the MAC block.   DHCP reservations are just as much a pain to manage.

We usually use the USER NAME and not the MAC for Surfcontrol blocking,
but there are some rare cases where we have to use MAC to block as the
PC doesn't log into the domain/ad/etc.

Whatever you decide to use, I'd suggest to keep a notebook with a copy
of who/what you blocked and why.  That's been a lifesaver here -- If I
unblocked Joe because his manager told me so, then 6 months later his
manager asks why I unblocked Joe., it's nice to not have to jogg the old
memory.
