IvanG.99607 (Customer) asked a question.
I am trying to set up SSH authentication using pam_radius_auth.so pointing to Okta RADIUS Agent. I can see the Linux box reaching Okta RADIUS Agent, but I get“Access denied. Invalid creds?”
For VPN scenarios the Okta RADIUS Agent is working fine with the same user I am testing.
I believe pam_radius_auth.so is missing something. I have tested with multiple secret sizes and added ‘ChallengeResponseAuthentication yes’.

Thank you for reaching out to Okta Support,
This looks like a configuration issue so please open a support ticket with us so we can discuss your settings and get a better understanding of your desired flow and environment.
Thank you,
