About setting up Radius

For details about how to set up Radius-general Linux technology-Linux technology and application, refer to the following section.

Hello everyone, for the environment.

I. Environment Introduction
1. Radius is used as the user authentication server, and windows server 2003 is used. All users in the network are stored here.

2. SSH server. Use the Redhat Llinux5 system. When a client logs on to the SSH server, the user used is verified as the user above the Radius, rather than the local user of the ssh server.

3. ssh client. Use the Solaris system. Log on to the ssh server on the ssh client and use the user to authenticate the user above the Radius. Not the local user on the ssh server.

Ii. Questions.
There is only one question here. You must configure the SSH server. Configure the ssh user authentication function of the ssh server to use the user above the Radius server. My idea is to configure the PAM verification module on the ssh server. However, once configured, it cannot be found.
I don't know where the configuration is wrong. Or, I am wrong at all. Please help me. Thank you.
