A method operative at an identity provider enforces a digital rights management (DRM) scheme associated with a piece of content. The identity provider is an entity that participates in a “federation” with one or more other entities including, for example, an service provider (e.g., a content provider), a DRM privileges provider, and a DRM policy provider. In one embodiment, the method begins by having the identity provider obtain and evaluate against a DRM policy a set of DRM privileges associated with the end user requesting access to the piece of content. Based on the evaluation, the identity provider generates a single sign on (SSO) message that includes a reference to the set of DRM privileges. The message is then forward to the service provider entity, which provides the end user a response.
