hi, we have an app (SP) that authenticate with gluu with SAML. our app has an "logout" button, which logout the application itself. if we also need to logout the SAML session on gluu server, should we call <gluu server>/idp/logout.jsp? what is the intended usage of logout.jsp? Do we add another logout button in our app's ui that redirect to <gluu server>/idp/logout.jsp upon clicking the "logout saml session" button? Thanks in advance.

Hi, Yes.. /idp/logout.jsp is for SAML logout from Gluu Server. You can call this ( https://hostname_of_your_Gluu_Server/idp/logout.jsp ) from your SP to perform logout from IDP side.

hi, Thanks for your promptly reply, in following case/steps: 1. user access our app (SP), redirect to gluu login page 2. user login with gluu account, redirect to SP site 3. user logout from our app (SP) locally 4. user go to gluu server and is able to see his "profile" on gluu server 5. user logout from gluu server, by clicking the logout button. is step no. 5 above the same as calling "idp/logout.jsp"? It seems that clicking logout button on the UI doesn't kill the SAML session on gluu server, is that by design? It seems strange that we need to add an UI or something on our app to trigger the "saml logout" on gluu server, and why there isn't UI on the gluu server that perform the same task? Thanks and have a nice day.

hi, In addition to that, after calling idp/logout.jsp, is there any way to redirect the page back to SP? Thanks

>> user access our app (SP), redirect to gluu login page >> user login with gluu account, redirect to SP site >> user logout from our app (SP) locally If you call IDP's logout link directly from SP that should redirect your users to Gluu Server login page again.

hi, can you please confirm the following question: Does clicking "logout" on gluu's ui (on gluu site/server) terminate all my SAML session on that gluu server? note: because on our implementation, logout from gluu server itself does NOT terminate previously authenticated SAML session.

Yes it should. >> note: because on our implementation, logout from gluu server itself does NOT terminate previously authenticated SAML session. Are you using 2.4.4? If logout happening... we need to do QA and see what's up there.

hi, yes, the gluu version is 2.4.4. a.) logout from gluu server's ui, which calls "/identity/logout" b.) calls <gluu server>/idp/logout.jsp After performed (a) above, SP can login WITHOUT authenticate again. After performed (b) above, SP need to authenticate again. Does that means (a) above DOESN'T terminate my previously authenticated SAML session ?

Hi there, I was wondering what you mean with > If you call IDP's logout link directly from SP that should redirect your users to Gluu Server login page again. How does the Gluu Server determine to which SP login page it should redirect? If I simply call idp/logout.jsp, I end up with seeing the green "Logged out" page at /finishlogout. Problem is, when I click "Sign in again" the SP-context is lost and after I have logged in, I will get redirected to /identity/home instead of the SP's homepage. Any idea what I missed? :( Thank you for any feedback!

Hi Markus, Apologies for confusion... >> How does the Gluu Server determine to which SP login page it should redirect? Not _SP Login_ but _Gluu Server login page_ which is IDP. >> If I simply call idp/logout.jsp, I end up with seeing the green "Logged out" page at /finishlogout. Correct. In our previous versions... instead of showing green "Logged out" we used to show the initial login ( oxAuth login ) page. Though it's possible to do some few tweaking and achieve that old behavior but this green login page is 'by design' now. >> Problem is, when I click "Sign in again" the SP-context is lost and after I have logged in, I will get redirected to /identity/home instead of the SP's homepage. Yes, that's perfect workflow. Whenever there is logout happening... all relationship with SP should be totally gone.

Hi Mohib, alright. That clears up a lot for me. Though it might be a bit off-topic, can you give me a hint how to change the default route after login from /identity/home to somewhere else? Thanks Markus

>> can you give me a hint how to change the default route after login from /identity/home to somewhere else? I think it will be helpful if you can describe the use case a bit more. Not clear much to me yet...

oh, sorry :( So, I have a simple SAML2 scenario: 1. Go to SP Url 2. Redirect to Gluu-Login 3. Redirect back to SP all good. Now, when I logout via: 4. .../idp/logout.jsp 5. Redirect to .../finishlogout 6. Click on Sign In Again 7. Redirect to Gluu-Login 9. Logging in... After I login now, I get to the /identity/home Dashboard of the user. And it makes sense to me regarding your answer above. But from a user's perspective it doesn't make sense. He/she would expect to get back to the SP's primary page. So it really comes down to the question: When I directly login into the Gluu server (without being redirected here) - how can I change the default "Landing page" for a user after login. Best Markus

>> He/she would expect to get back to the SP's primary page. It won't go to any SP page. User need to 'initiate login' by using SP's SSO link.
