Front-channel Logout

The call to /didmos/logout ends the OIDC session and redirects the user to the URL which is configured in the RP client configuration post_logout_redirect_uri in didmos2-auth. This removes all the session related data from didmos2-auth persistent storage and removes the following cookies:

  • didmos_backend_discovery
  • didmos_local_sso or didmos_sql_sso (which ever backend is activated)

The above cookies are used to regulate the SSO session in didmo2-auth.

It is important to note that if didmos2-auth is being used with a 3rd party backend, for example, any external SAML IdP or any external OIDC, then the user session with those external entities will not be logged out. It is only the front-channel logout which takes place by invoking the /didmos/logout.
