Description of our problem : SSO doesn't work
-on the first connexion from vpn client we insert two time the login and password :one time for the client vpn and the seconde time for CAA (clean Access agent).
-although for the other connexion that succeed, we insert only one time the login and password (for vpn only) and for CAA the connexion is done automatiquely and a some hours later we reinsert two times login and password for vpn and CAA.
The following steps are done to configure Cisco NAC Appliance to work with a VPN concentrator:
Step 1 Add Default Login Page =ok
Step 2 Configure User Roles and Clean Access Requirements for your VPN users =ok
Step 3 Enable L3 Support on the CAS = ok
Step 4 Verify Discovery Host =ok (CAS IP ADDRESS 192.168.2.11)
Step 5 Add VPN Concentrator to Clean Access Server =ok (ASA IP ADDRESS 192.168.2.1)
Step 6 Make CAS the RADIUS Accounting Server for VPN Concentrator =ok
Step 7 Add Accounting Servers to the CAS (accounting server is CAM IP ADDRESS 192.168.20.10)
Step 8 Map VPN Concentrator(s) to Accounting Server(s)=ok
Step 9 Add VPN Concentrator as a Floating Device =ok
Step 10 Configure Single Sign-On (SSO) on the CAS/CAM =ok
the database for vpn authentication is cisco secure acs(192.168.1.30).
Tanks to any anybody to give us a possible solution.
