In accordance with various embodiments, systems and methods that provide for authorization of access to protected resources. Such a system can include a plurality of applications, executing on one or more application servers. The system can also include an authorization server which is operable to interface with one or more remote and/or non-co-located third party authentication servers. Each application can (a) receive a request for authorization to access a controlled resource; (b) redirect the request for authorization to a configurable authentication endpoint identifying a third party authentication server; (c) receive authorization information from the third party authorization server; and (d) issue an authorization code for access to the protected resource.
