After some troubleshooting, we were able to get 591 to work as well (aka the MAC we were using for testing had both a network cable plugged in and wireless turned on and it was using the path of least resistance).  We are working with Cisco in getting some log files for 590 to see why it isn't working.

Subject: Re: Mac OS X 10.7 Lion Receiving HTTP response error

We were already running 4.8.2 on or CAM and CAS.  I downloaded 4.8.2.591 from the Cisco Support site manually and installed to my macbook pro running Lion 10.7.  Everything is working as it should be.  After a successful test I uploaded the updated mac installer agent using the gzipped tar file downloaded from the Cisco Support Site to my manager and have also had success in the manager distributing the updated agent.  At least in my environment 4.8.2 is working with nac agent 4.8.2.591 and OSX Lion.

Thank you,
