Identity Server generates metadata for server communication and identification. You can obtain metadata through URL or XML document and then enter it in the system while creating the reference. Metadata is traded with federation partners and supplies various information regarding contact and organization information located at Identity Server. Metadata is generated automatically for SAML 2.0. You enter it manually for SAML 1.1.
IMPORTANT:SAML 2.0 and Liberty 1.2 define a logout mechanism whereby the service provider sends a logout command to the trusted identity provider when a user logs out at a service provider. SAML 1.1 does not provide this mechanism. When a logout occurs at the SAML 1.1 service provider, no logout occurs at the trusted identity provider. A valid session still runs at the identity provider, and no credentials need to be entered. To log out at both providers, users must navigate to the identity provider that authenticated them to the SAML 1.1 service provider and log out manually.
