The use of federation features in Access Manager varies depending on the release.
When you integrate with Identity Federation:
11g Release 1 (11.1.1) sites, and those upgrading from 11g Release 1 (11.1.1) to 11g Release 2 (11.1.2), can use the integration.
See Integrating Access Manager 11gR2 with Identity Federation 11gR1 in the Oracle Fusion Middleware Integration Guide for Oracle Identity Management Suite.
Sites with new 11g Release 2 (11.1.2) installations can leverage federation features using the Oracle Access Management Console.
