Hi ,
One of my linux server running oracle linux 6.9 OS and centrify client is installed on it to integrate with AD . AD intergration is done and all my users are login to server with AD credentials . No issues in login .
As a additional security i want to implement two factor authentication with pam-radius . I have installed the pam-raidus rpm and point the server to secureauth server . I have enabled usepam=yes in ssh config file and restarted the machine. After reboot 2 factor authentication is not working. I'm able to login with normal ssh . Need help on configruing radius client . I had seen many online doc but it didn't help me.
