OpenSSO Enterprise allows you to continue using an existing SiteMinder deployment for authentication while leveraging the more advanced features of Federation Access Manager.
OpenSSO Enterprise quickly enables federation protocols for SiteMinder without few changes to the existing infrastructure.
OpenSSO Enterprise supports a variety of industry standard protocols such as SAMLv2 , ID-FF, ID-WSF, WS-Federation, XACML, WS-*, and others.
OpenSSO Enterprise supports any generic LDAP repository for users, and can work with the existing SiteMinder database.
OpenSSO Enterprise leverages its own configuration data store, which minimizes the need to migrate data from a different data store.
