We are using CA API Gateway to authenticate users against CA SSO.
Currently there isn't any feature or assertion to initiate logout and session grace period etc. in CA API Gateway which are petty basic feature along in authentication with SSO.
Also as both products are under Broadcom, we expect CA API Gateway to act as one of web agent.
Please consider these in your road-map.
