Issue
RADIUS client <ANY>
Error: "Agent host not found" in RSA Authentication Manager activity log
RADIUS client <ANY>
Cause
Resolution
1. In the \rsa\radius\ directory, edit the securid.ini file and change these lines as such:
[configuration]
; enable = 0 (leave this commented out)
CheckuserAllowedbyClient=0
NOTE: The first line "[configuration]" above must be uncommented
2. Restart the RSA RADIUS service (through the RSA Control Panel) or, in UNIX, with the following commands:
/etd/init.d/sbrd stop force
/etc/init.d/sbrd start
Notes
This makes the system more flexible as it allows any radius client with the proper RADIUS Shared key to be able to authenticate. This does have two drawbacks:
1. since <ANY> radius client will have a chance to authenticate, this is less secure than having a specific list of clients
2. The AM logs may not show the client names, which may not be acceptable in all environments
See A60636 for a similar solution for AM7.1 or RSA Appliance 3.0
