The single logout (SLO) profile enables users to log out of all participating sites in a federated session from any site.
The associated identity provider (IdP) federation deployment manages all logout requests and responses for participating sites. If a participating site returns an error, other participating sites might not receive their logout requests. In this scenario, PingFederate returns an error message to the end users.
The logout messages can be transported using any combination of bindings described for SSO (POST, artifact, or redirect). See the diagrams under SAML 2.0 profiles for illustrations of these message flows.
About session cleanup
When a service provider (SP) receives an SLO request from an IdP, the session creation adapters must handle any session clean-up involving the local application.
