Fix Recommendation

Configure the OL 9 SSHD to use the UsePAM interface by adding or modifying the following line in "/etc/ssh/sshd_config" or in a file in "/etc/ssh/sshd_config.d".

UsePAM yes

Restart the SSH daemon for the settings to take effect:

$ sudo systemctl restart sshd.service

Check Contents

Verify that OL 9 SSHD is configured to allow for the UsePAM interface with the following command:

$ sudo /usr/sbin/sshd -dd 2>&1 | awk '/filename/ {print $4}' | tr -d '\r' | tr '\n' ' ' | xargs sudo grep -iH '^\s*usepam'
UsePAM yes

If the "UsePAM" keyword is set to "no", is missing, or is commented out, this is a finding.
