Add a large number of RADIUS clients to Authentication Manager.
How to configure <ANY> RADIUS client.
How to allow the system to authenticate users from clients without agents.
What to do if authentication fails after adding <ANY> RADIUS client in Security Console.
If you need to add a large number of RADIUS clients to Authentication Manager, instead of adding an agent to each RADIUS client, You can configure an <ANY> RADIUS client and enter the same shared secret for each RADIUS client.
When an ANY client sends a network request to its' associated RADIUS server, the RADIUS server confirms the shared secret and forwards the request without any client information to Authentication Manager for authentication.
First, add an <ANY> RADIUS client by following the below steps:
Log into the Authentication Manager primary's Security Console and navigate to RADIUS > RADIUS Clients > Add New.
Enable the option to Accept authentication requests from any RADIUS client using the shared secret specified for this client.
Enter the RADIUS Shared Secret.
Now allow the system to authenticate users from clients without agents by following the steps below:
Log into the Operations Console on the primary and navigate to Deployment Configuration > RADIUS Servers.
Click on the server name and select Manage Server Files.
Click on securid.ini file and select Edit.
Set the file parameter for CheckUserAllowedByClient to 0. By default, this parameter is set to 1, which allows the system to authenticate users from clients with an assigned agent.
Click Save & Restart RADIUS Server. so the file changes can be read by the system.
Changes made to RADIUS server files are not replicated to other servers in your deployment. Repeat steps 1 - 5 on each replica in your deployment.
