Re: [cas-user] TGT Expiring not requiring log-in

[Ben Chang]

I’m using Java CAs.  Ok, so my application redirects to cas for login and logout. 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.  Ben Sent from my iPhone On Nov 7, 2024, at 1:46 PM, Ray Bon <r...@uvic.ca> wrote:  Ben, cas/logout is an endpoint in cas. 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?

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?
