Description Filip Krska 2022-09-19 14:33:14 UTC

Description of problem:

`man sshd_config` states

   If UsePAM is enabled, you will not be able to run sshd(8) as a non-root user.  The default is no.

while RHEL/Fedora distro default and only supported is `yes` (as explained in /etc/ssh/sshd_config and logged to /var/log/messages):

Sep  6 08:44:47 server sshd[2787]: WARNING: 'UsePAM no' is not supported in Fedora and may cause several problems.

Version-Release number of selected component (if applicable):

openssh-8.0p1-13.el8

How reproducible:

Always

Steps to Reproduce:
1. man sshd_config
2. less /etc/ssh/sshd_config
3. grep "UsePAM" /var/log/messages

Actual results:

Man page states that The default is no and doesn't warn about only supporting the opposite.

Expected results:

Man page shall also cover the recommendation/necessity to set UsePAM to `yes` so it doesn't confuse users.

Additional info:

Please clone to RHEL 9, Fedora
