The integrated Identity Federation server supports the transport and receipt of request and response messages using either the Security Access Markup Language (SAML) 2.0 specifications, SAML 1.1, OpenID 2.0 or WS-Federation 1.1.

SAML and OpenID partners can be defined using the Oracle Access Management Console. WS-Federation partners can be created using WLST commands.
