HP-UX AAA Server A.08.02 Administrator's Guide

9 Configuring Proxies
AAA proxy is an entity that acts as both a client and a server. When a request is received from a
client, the proxy acts as a AAA server. When the same request needs to be forwarded to another
AAA entity, the proxy acts as a AAA client.
Figure 25 illustrates both ends of a proxy configuration relative to the local host. When the local
host receives a request that it will authenticate, the server that forwarded the request is called the
proxy server. When the local host forwards a request for another server to authenticate, the other
server is called the remote (or home) server. A request can be forwarded through several networks
before it reaches the home server.

Navigating the Proxy Screen
The server configuration must include all the servers that forward messages to or receive forwarded
messages from the AAA server. If a remote server is not included in the configuration, the server
does not handle or forward requests. The Proxies screen shown in Figure 26 allows you to add,
modify, or delete a proxy in the server configuration.

Changing the Default localhost Proxy Settings
The HP-UX AAA Server includes a preconfigured proxy entry named localhost for use in loop-back
testing. You must change the default shared secret value for the localhost proxy, or delete it if
you do not plan to use loop-back testing.
To change the shared secret for the default localhost proxy, complete the following steps:
1. From the navigation tree, click Proxies.
2. On the Proxies screen, click the localhost link.
