Abstract: A system and method for providing user authentication and authorizations for an enterprise. An enterprise dynamic network authorization system includes an authorization server that receives requests from users for access to services. The authorization server uses user service subscriptions and access rules associated with the services to determine if the user should be authorized to access a service. The system may provide authentication for provisioned services having their own authentication databases through the use of an authorization remote management interface. The system may further include an administration server coupled to the authorization server. The administration server may be used by an administrator to add, modify, and delete user authorizations within the enterprise dynamic network authorization system and remote systems using the authorization remote management interface.
