Hi all,
 
Does anyone use Cisco's NAC with the posture checking agent out there
for windows endpoints?  If so, I would love to hear about how you
managed to get it to play nicely with your AD environment!
 
Because the agent doesn't run until *after* you pass the GINA, it stops
certain GPO based settings that require trusted network resources (eg.
folder redirection) and then gets in a race condition with other scripts
and software that may need access to trusted network resourced (eg.
login scripts that map drives and any other agents that log into
internal servers).  If it loads last, everything is broken.  Even if it
loads quickly, some things are broken.
 
This seems to be a fundamental architectural issue - defeats me as to
why the agent doesn't check in as a machine based entity on boot, rather
than waiting for user login.  I know there are options that can be based
on user or group, but that should be an additional option, not a design
assumption!  The only alternative appears to be to defeat the purpose of
the "unauthenticated" group and blow a load of firewall holes through
it, thus rendering it semi-useless when inline since you're no longer
protecting your network from unauthorised hosts (MAC address can only
come from the agent in a VPN setup, unlike the L2 functionality on
internal switches).
