This article describes the authentication service in Nexus Hybrid Access Gateway.

How does authentication work?

When a user uses a web browser to access a resource, the request flows through a web of specialized services: the access point, the policy service, the authentication service, and back again. But for the user, the single point of contact is the web browser. The access point verifies the identity of the user by forwarding the user credentials via the policy service to the authentication service, which in turn compares the information with credentials stored in the user storage. When the control is completed, a request accept is sent to the access point which allows the user to enter.

What does the authentication service do?

The authentication service handles authentication of users accessing resources. The authentication service supports several authentication methods.The authentication service may also use proxy authentication requests to an authentication server using third-party authentication methods. In this case, you configure a RADIUS back-end server as an authentication server.

An authentication service was added and configured during the set up of Hybrid Access Gateway.
