As an identity provider and single sign-on manager, Apereo CAS is able to manage and maintain the collection of active single sign-on sessions for users. Furthermore, administers are able to review all active sessions and remotely destroy a user’s single sign-on session, effectively logging the user out of all applications via single logout if that is an activated option.

This blog post presents an overview single sign-on management facilities in CAS, via the following starting position:

SSO Sessions

Administrative management of CAS single sign-on sessions is provided via a dedicated ssoSessions endpoint:



This actuator endpoint allows one to fetch all single sign-on sessions with the given type. Some sessions are directly established with CAS and some are created via proxy authentication. What’s important here is that this endpoint requires that the underlying ticket registry and store is able to store, maintain and return a collection tickets that represent the single sign-on session. You will NOT be able to collect and review sessions, if the ticket registry does not have this capability.

Let’s play around with this a bit.

Retrieving SSO Sessions

Fetch all active SSO sessions:

curl -X GET https://sso.example.org/cas/actuator/ssoSessions | jq

Fetch all active SSO sessions for a single user:

curl -X GET https://sso.example.org/cas/actuator/ssoSessions\?username\=casuser | jq

Removing SSO Sessions

Destroy a single active SSO session:

curl -X DELETE https://sso.example.org/cas/actuator/ssoSessions/TGT-1-g2tM-TMc  | jq

Destroy all active SSO sessions for a given user:

curl -X DELETE https://sso.example.org/cas/actuator/ssoSessions\?username\=casuser | jq

Destroy all active SSO sessions:

curl -X DELETE https://sso.example.org/cas/actuator/ssoSessions\?type\=ALL | jq
