Abstract
An authorizing apparatus for use with a client that connects to a first server in a network includes a second server that authorizes session requests of the client for the first server. Resource allocation data is available to the second server and indicates whether a session may be established between the client and the first server. The second server has information that associates an entity that is associated with one or more clients, and information that associates the second server to a third server that is authoritative for the second server and the associated clients. When a request to establish a session between the client and the first server is received, the second server determines, based on one of the records that is associated with the client, whether the session may be established when the client is associated with the entity. If not, the second server requests a global authorization server to determine whether a session is allowable. As a result, session management is resolved locally when possible, and over-subscription of clients to servers is prevented.
