ClearPass admin login - via external RADIUS server

    I just want to make sure I'm clear and up to date on this - is TACACS+ and local users the only option for admin user login to CPPM boxes? I have read that this is the case but the info was a few years old.

     

    We have an external RADIUS server which we use for management logins to our general network equipment so it would be ideal to use this for admin login to CPPM if possible.

    I have the same issue you do. First they tell me to use SAML SSO for admin log in but that causes issues as our clearpass server doing management log in doesn't share same certs and has to rely on other parts of the infrastructure. If oyu use TACACS+ you can only specify 1 IP address which breaks redundancy since my 3 Clearpass for management accounts are in different subnets. This futhure puts more reliance on other parts of our network for something that needs to run independant of failures of things on the network.

    I have the same issue, have you found a way to make it work with an external RADIUS server?

    You can try to use RADIUS Proxy, or Token Server in your ClearPass Admin Authentication service. Both should use a backend RADIUS server for the authentication.

    Thank you Herman. 
    I found this post which did not help much but I am starting to think it may not be possible?

    When I tried using proxy Radius like you suggested, I get stuck when trying to create the enforcement profiles. If I try to use a "TACACS+ Based Enforcement" template, it will then allow me to add cpass:CLI and cpass:HTTP services. When choosing "RADIUS Based Enforcement" template, I can't add those two services. 

    Any additional suggestions?

    FYI We use Radiator running on Linux as our RADIUS server for admin user authentication.

    Hi all,

    For reference we use Radiator TACACS+ and our configuration end up being:

    AuthorizeGroup admin permit service=cpass protocol=http {AdminPrivilege="Super Administrator"}
    AuthorizeGroup admin permit service=cpass protocol=cli {AdminPrivilege="Super Administrator"}

    Hopefully this helps someone in the future.
