I have the same problem on one of our appliances running v3.3(1). We have 4/5 others that run the same version but don't have this issue. We'll be upgrading to v3.3(3) soon, but would like to know if there's a real solution.</P></BODY></HTML> Mon, 14 Nov 2005 18:53:20 GMT https://community.cisco.com/t5/network-access-control/csa-authentication-agent/m-p/471047#M5837 mmletzko 2005-11-14T18:53:20Z
