Tivoli® Federated Identity Manager supports single sign-on through use of the OpenID protocol.
This overview describes the Tivoli Federated Identity Manager implementation of OpenID. The information in the overview enables an administrator to deploy and configure single sign-on federations.
The OpenID specifications refer to an OpenID Provider or Identity Provider as the party who asserts that a user owns a particular identity URL. A Relying Party or Consumer is referred to as the party who receives that information from the identity provider. In Tivoli Federated Identity Manager, the term identity provider is a direct match for the OpenID concept of OpenID Provider or Identity Provider. The OpenID Consumer fits well into the Tivoli Federated Identity Manager concept of service provider.
Both OpenID 1.1 and OpenID 2.0 are supported.
