Radius services stopped working in CPPM

  • 1.  Radius services stopped working in CPPM

    Posted Feb 14, 2024 12:36 PM

    Hello All ,

    We have an 802.1x service, and one of the AD servers configured in authentication source is not reachable.
    The complete radius service, including mac authentication, is unavailable during the problem period. 
    We have observed AD connection loss and AD/LADP failures in Event Viewer. Has anyone else encountered this problem?
    Once the AD server is reachable, all radius services are operational again.
    How to address the issue permanently ?

    During these scenarios do you actually see the "Radius server" Service in a "stopped" state (shown in Services Control)?

    No it is not in the stopped state and we didn't perform any service restart.

    For clarification:

    Are you saying that an AD outage is causing issues with CPPM service enforcement, on services that are not configured with that AD Authentication Source?

    Yes Zak Chalupka , 

    whole radius services are not working due to  a single unreliable AD server. Even MAC authentication services are not working .Only Tacacs auth service are authenticating the users during the issue period.

    Can you post a error output from a fail auth during that time?
