So set "limit_proxy_state = true", and the system will be protected. That's what the message is trying to tell you.
Should I take any action?
Read the message and do what it says?
We will be releasing a new version of the pam_radius module shortly. It will add fixes for the client.
You will still continue to see the above messages (or some variant of them) until you follow the instructions in the message, and set the new configuration flags.
