Has anyone had any luck integrating vpn with NAC 4.9?  We are currently trying 
to implement this in our environment with some mixed/strange results.  
Currently windows clients sign into the nac agent via sso, remediate, receive 
the message that they have full network access, and immediately try to 
remediate themselves again and again. On mac clients running 10.7.2 the nac 
agent fails to login via SSO and the agent never pops up to allow for manual 
login.  We have tested another mac running 10.6 and surprisingly this mac 
works perfectly.  The agent logs in via SSO, remediates, and stays logged in 
allowing access until we log it out.

Thank you,
Kelly Slone
