The identity management and access management are two different entities. In classical situations, access management relies on an Identity Provider to verify the user, and builds on top of it to map the identity of the user/system with what it can do in an environment. Typically Role Based Access Control (RBAC) is a standard concept that is followed to establish an access control layer. A support layer is added to make use of this access management, basically a set of protocols to use this with other applications.
