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.

Complete!

Actual results:
$ id apache
uid=48(apache) gid=100(users) groups=100(users)


Expected results:
$ id apache
uid=48(apache) gid=48(apache) groups=48(apache)


Additional info:
I'm aware that setting USERGROUPS_ENAB to 'no' is a bit non-standard, but... I've reviewed .spec file in httpd source package and replacing:
%pre
# Add the "apache" user
/usr/sbin/useradd -c "Apache" -u 48 \
	-s /sbin/nologin -r -d %{contentdir} apache 2> /dev/null || :

with:
%pre
# Add the "apache" user
/usr/sbin/useradd -c "Apache" -u 48 -U \
	-s /sbin/nologin -r -d %{contentdir} apache 2> /dev/null || :

as hinted by 'man useradd' should fix this easily.

This seems to be a different problem. Judging from the yum output,

the 'groupadd' command (which *is* apparently being called, as opposed to RHEL-7.2 httpd) is having troubles writing to /etc/group. I am guessing this might have to do with the file's SELinux context, file attributes or even the mount options of the /etc filesystem (if it is mounted). The httpd preinstall scriptlet does everything it should:

# rpm -q --scripts httpd
preinstall scriptlet (using /bin/sh):
# Add the "apache" user
getent group apache >/dev/null || groupadd -g 48 -r apache
getent passwd apache >/dev/null || \
  useradd -r -u 48 -g apache -s /sbin/nologin \
    -d /var/www -c "Apache" apache
exit 0
...

> This seems to be a different problem. Judging from the yum output,

You are right. Sorry for not checking that. 


I am having some other issue. I am facing issues in adding a user itself.
    # useradd test
    useradd: failure while writing changes to /etc/passwd`


To add a user and group, I have to edit those /etc/passwd & group file now. 

Thanks for pointing it out.
