RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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

I believe we have fixed it in rhbz#1953807

*** This bug has been marked as a duplicate of bug 1953807 ***

Fixed is it?

It is absolutely mind-boggling the way Red Hat never, ever, manages to fix anything properly.

Here is an extract from the default sshd config on a fully updated RHEL9 server i just built:

# WARNING: 'UsePAM no' is not supported in RHEL and may cause several
# problems.
#UsePAM no

DO YOU NOT SEE THE PROBLEM?

According to that, the default is "UsePAM no"
And, according to that, "UsePAM no" is not supported in RHEL.


ARE YOU REALLY TRYING TO TELL ME THAT RED HAT IS SHIPPING SSH WITH A DEFAULT CONFIGURATION THAT IS NOT EVEN SUPPORTED BY Red Hat??
THE LEVEL OF STUPIDITY IS JUST MIND-NUMBING.

JUST FIX IT PROPERLY PLEASE.
