Ben, By default cas sends a back channel logout request to your application. This has to be on https. If you are using localhost (cas and your app running locally), then you must be using a self signed cert. see https://apereo.github.io/cas/7.1.x/installation/Troubleshooting-Guide.html#ssl--certificates Both cas and your app need to know about the certificate (you can add it to the java trust store). Though cas must be validating service tickets (there will be an audit log)???
There is no logout when the TGT expires. see https://apereo.github.io/cas/7.1.x/protocol/CAS-Protocol.html#webflow-diagram Ray On Thu, 2024-11-07 at 15:22 -0500, Ben Chang wrote: Right, and I was using the per service example/code to try to end the sso session. It seems to work by my logs (where it has a logout_success log albeit with unknown client_ip and server_ip), but it isn’t forcing the user to sign back in even after clicking other endpoints. I only set it to 5 (and 125) like the example in the tab to see if it worked, but it isn’t. That’s been the crux of my issue. I’m sure I’m missing or misunderstanding something but I’m not sure what. I’m running the environment locally so I have my serviceID to be “localhost” so that should be correct. I’m able to sign in and sign out, just not force out after the time expires/logout_sucess log .

Cas does not manage application sessions (one cas can support multiple applications). Cas is only about authentication (and a few other related items). Set your application session to the length you want. Think about the user experience if someone was in the middle of a task and some other system logged them out.

Looking at the SSO page, seems like I don’t need to specify the LogoutURL and LogoutType since the default should work? So if I make a service with ticketGrantingTkcletExpirationPolicy and a maxTimeToLiveInSeconds of 125, what’s the purpose of it if it doesn’t force logout or do anything? Is there a service to force logout after a certain time? I was under the impression if the tgt ticket expires and is removed, then you would have to relogin.

It tells cas to destroy its own session and send logout requests to all services associated with the TGT (depending on global and service config). see https://apereo.github.io/cas/7.1.x/protocol/CAS-Protocol-Specification.html If the service id was not right, cas would tell you. When a TGT expires, nothing noticeable will happen; no logs, no single logout. Depending on how tickets are stored, a cleaner may remove the TGT (there may be logs, but no single logout). Cas logout (single logout) only happens when the user initiates it, by visiting cas/logout or logging out of an application that redirects to cas/logout. The payload that is sent to the application/service can be seen on the page Dmitriy linked. This payload is what your cas client needs to process (you do not want random logout requests being sent to your app). Once processed, your cas client can trigger a logout in your application. Cas outbound calls and back channel inbound calls are all https (so be sure your certs are correct). What cas client are you using? Ray On Thu, 2024-11-07 at 06:44 -0800, Ben wrote: Thanks! So the main thing is that I’m trying to use it for a specific application so I created a service to target the specific application (assuming I have the serviceID right). When I do the non TGT logout via clicking the links on the application to the back-end, it works fine so my application knows how to handle the request. I tried changing the timeout to 125, but that didn't seem to do anything. Also, when you mean cas/logout, do you mean the back end call? I do see that when the timeout "occurs", it cant seem to find the server and client ips. Is that maybe a cause? When I log in, it has client and server IPs 2024-11-07 09:41:04 ============================================================= 2024-11-07 09:41:04 WHEN: 2024-11-07T14:41:04.250032600 2024-11-07 09:41:04 WHO: omitted 2024-11-07 09:41:04 WHAT: omitted 2024-11-07 09:41:04 ACTION: LOGOUT_SUCCESS 2024-11-07 09:41:04 CLIENT_IP: unknown 2024-11-07 09:41:04 SERVER_IP: unknown 2024-11-07 09:41:04 ============================================================= Ben On Wednesday, November 6, 2024 at 2:51:33 PM UTC-5 Ray Bon wrote: Ben, logoutURL is where cas will send the logout request (BACK_CHANNEL) or redirect (FRONT_CHANNEL). Default is the url used during login. With back channel logout, cas sends a logout request to logoutURL. Your cas client has to process the request and perform the logout action. Check you cas client's documentation, and perhaps your configuration. Cas does not end your application's session; it can only suggest to your application to perform its own logout. I suggest removing all of the logout config you have add to cas (except for logoutURL only if it is not the same as the login url). Cas will perform a back channel logout by default. Then see how your application responds to the logout request. Ray P.S. I think the shortest time for TGT time to live is 2m, so you may have to wait this long or visit cas/logout On Wed, 2024-11-06 at 10:47 -0800, Ben wrote: But from the https://apereo.github.io/cas/7.0.x/installation/Logout-Single-Signout.html#casslodisabledPropertyConfig page, it appears under the "Service Endpoint for Logout Requests" section, if I set my logoutURL field to my application's log out, it CAS can get the app to logout?
