1. A domain controller configured to manage physical access to an access-controlled area of a distributed site of an electric power delivery system, the system comprising:
a communications interface configured to receive a physical access authentication request and authentication credentials from a communicatively coupled access control system associated with the access-controlled area; a processor communicatively coupled to the communications interface; and a computer-readable storage medium communicatively coupled to the processor and the communications interface, the computer-readable storage medium storing instructions that, when executed by the processor, cause the processor to:
identify, based on the physical access authentication request, physical access attribute information associated with a user entry included in a directory service managed by the domain controller, the directory service being stored on the computer-readable storage medium;determine, based on the physical access attribute information, whether the authentication credentials are associated with an individual having current access rights to the access-controlled area;generate, based on the determination, an authentication response indicating whether the authentication credentials are associated with an individual having current access rights to the access-controlled area; andtransmit, using the communications interface, the authentication response to the access control system. |
