1.269 OL09-00-002344

Information

OL 9 must enable the Pluggable Authentication Module (PAM) interface for SSHD.

GROUP ID: V-271707
RULE ID: SV-271707r1091833

When UsePAM is set to "yes", PAM runs through account and session types properly. This is important when restricted access to services based off of IP, time, or other factors of the account is needed. Additionally, this ensures users can inherit certain environment variables on login or disallow access to the server.

Solution

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
