I want to use TACACS to do ASA accounting, meanwhile the ASA need RADIUS to support ssl vpn authentication. Is that possible to achieve this object with only one ACS?
Yes, you can use both. You to add ASA as radius and tacacs.
ACS--> network configuration--->aaa-client
1) ASA--->126.96.36.199--->Authen using tacacs
2) ASA1---->188.8.131.52--->Authent using radius
Remember host name cannot be same.
