Computer system, method and program for managing authentication requests. At a gateway device to a network, packets of a message intended for said network are received. In response, fields within payloads of said packets which contain authentication or authorization information are read. In response, the message is redirected to an authentication server. In response to receipt of the redirected message from the gateway device, the authentication server determines that a requester who sent the message to the gateway device is authorized to access a target resource specified in the message and responds to the gateway device that the requester is authorized to access the target resource. In response, the gateway device responds to the requester that the requester is authorized to access the target resource. In response to the response from the authentication server that the requester is authorized to access the target resource, the gateway device notifies a server hosting the target resource that the requester is authorized to access the target resource. If the gateway device receives a subsequent message from the requester to utilize the target resource, the gateway device forwards the message toward the server hosting the target resource.
