title: WSO2 with OIDC: How to Configure Logout Endpoint
body: <p>I am running WSO2 Identity Server 5.7.0 and using OpenID Connect. I currently receive an invalid redirect error when I navigate to <a href="https://MY_DOMAIN/oidc/logout" rel="nofollow noreferrer">https://MY_DOMAIN/oidc/logout</a>, when I think I should be redirected to a page under the /authenticationendpoint resource. I noticed in the "Logout Endpoint URL" under Resident Identity Provider > Inbound Authentication Configuration > OAuth2/OpenID Connect Configuration is set to "<a href="https://MY_DOMAIN:-1/oidc/logout" rel="nofollow noreferrer">https://MY_DOMAIN:-1/oidc/logout</a>". </p>
  
  <p>I am assuming the Logout Endpoint URL is configured based on the OIDCLogoutEPUrl config value in identity.xml. In my identity.xml file this value is set to         ${carbon.protocol}://${carbon.host}:${carbon.management.port}/oidc/logout.</p>
  
  <p>My first question: Is the Logout Endpoint URL value only copied to the database when WSO2 is first run and the databases are initialized?</p>
  
  <p>Followup question: If the answer to that is no, how can I configure that value without re-seeding the database?</p>
  
  <p>Thanks for your help.</p>
