Jazz Authorization Server (JAS) is a Liberty !OpenID Connect Provider and it can be configured to further delegate authentication to a [[JASandSAML][SAML Identity Provider]] or a [[JASandOIDCProvider][Third Party OIDC Provider]]. The expectation is for Single Sign-On and Sign-Out to work between ELM and non-ELM applications that are both configured to use the same Provider. 

The focus on this Article is on Single Sign-On and Logout. It is assumed that you have configured JAS with either a SAML !IdP or a Third Party OIDC Provider. 

---++ JAS configured with a SAML !IdP

---+++ Configuring Single Sign-On

The default configuration of JAS configured with SAML !IdP indicates the !IdP to force the user to re-authenticate. We would need to change this configuration for SSO to work between ELM and Non-ELM applications.

Steps to update the configuration:
   * Edit =appConfig.xml= file located at =[JAS_HOME]\wlp\usr\server\jazzop\appConfig.xml=
   * Search for =samlWebSso20= section and update the parameter _forceAuthn_ to _forceAuthn="false"_ and add parameter _spLogout="true"_
   <verbatim>
   <samlWebSso20 
		id="defaultSP"
		spCookieName="jazzop_sso_cookie_idp"
		forceAuthn="false" 
		authFilterRef="samlAuthFilter"
		spLogout="true" >
   </samlWebSso20></verbatim>
   * Test Single Sign-On between ELM and Non-ELM applications

---+++ Configuring Single Sign-Out

You would need to perform the following additional configuration changes in JAS.

   * First confirm if the SAML =idpMetadata.xml= file contains =HTTP-POST= binding for =SingleLogoutService=. Currently Liberty only supports =HTTP-POST= Binding and not =HTTP-Redirect= Binding.
      * An example entry looks like this
      <verbatim><md:SingleLogoutService Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" Location="https://mysaml.example.com/mysaml/slo" /> </verbatim>

   * Next Upgrade the Liberty profile for JAS to 22.0.0.4 or higher. Upgrade requirement due to the fix of [[https://github.com/OpenLiberty/open-liberty/issues/18177][Issue 18177]] .
      * Download Liberty version 22.0.0.4 https://www.ibm.com/support/pages/node/6568759
      * Upgrade Jazz Authorization Server - https://www.ibm.com/support/pages/upgrading-liberty-ibm-engineering-lifecycle-management-jazz-authorization-server

   * Edit =appConfig.xml= file located at =[JAS_HOME]\wlp\usr\server\jazzop\appConfig.xml=
   * Search for =samlWebSso20= section and change the =spCookieName= parameter value from =jazzop_sso_cookie_idp= to =jazzop_sso_cookie_saml_idp= or to any name of your choice.
   <verbatim>
   <samlWebSso20 
		id="defaultSP"
		spCookieName="jazzop_sso_cookie_saml_idp"
		forceAuthn="false" 
		authFilterRef="samlAuthFilter"
		spLogout="true" >
   </samlWebSso20></verbatim>
   * Add =/end_session= to the Authentication Filter =requestUrl=
 <verbatim>
   <authFilter id="samlAuthFilter">
        <requestUrl id="samlRequestUrl" urlPattern="/authorize|/end_session" matchType="contains" />
        <userAgent id="samlUserAgent" agent="Mozilla|Opera" matchType="contains"/>
   </authFilter></verbatim>

---++ JAS configured with a Third Party OIDC Provider

---+++ Configuring Single Sign-On

When ELM is configured with a Third Party OIDC Provider , no changes are needed.

---+++ Configuring Single Sign-Out

With the default configurations the Logout operations from ELM does not complete. You would need to perform the following additional configuration in ELM.
=This workaround would work if you can directly access the OIDC Logout URL=

   * Request your Administrator to share the OIDC Logout URL
      * Sample logout URL from a customer  =https://preprod.example.com/ui/oidcclient/logout=
   * In each ELM application =jts, ccm, qm, rm, gc and dcc= perform the following:
      * Access Advanced Properties =https://[ELM_URL]/[app]/admin#action=com.ibm.team.repository.admin.configureAdvanced=
      * Search for the property =Web Logout URI= and update the value to the Logout URL received
      * Search for the property =Trusted URIs for client authorization and redirection= and update the value with the Logout URL received
   * Test Logout from ELM Applications

---++ Testing

After applying the Single Sign-On and Sign Out configurations mentioned in the previous steps, following are the results

   * Single Sign-On is achieved between ELM and Non-ELM applications
   * Logout from an ELM Application will logout via the !IdP logout URL and all other ELM Applications are logged out

   * Logout from a Non-ELM application - ELM applications are NOT logged out immediately
      * Post the SSO timeout which is set to 2 hours by default (can be changed), the applications are redirected to the !IdP and existing sessions are logged out
