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 Jan Pazdziora (Red Hat) 2014-09-17 20:39:28 UTC 
Description of problem:

The dirsrv user/group is only created when ipa-server-install is run. That makes it hard to move IPA's data from container to a data volume as in vanilla container the records won't be there and the directory server will refuse to start: Unknown user 'dirsrv'.

And if we do this, we could just as well hardcode some reasonable uid. For example, httpd does

/usr/sbin/useradd -c "Apache" -u 48 \
	-s /sbin/nologin -r -d /usr/share/httpd apache 2> /dev/null || :

For dirsrv user, uid 389 could be used (but we'd need to verify if it's not used by someone else).

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

389-ds-base-1.3.1.6-26.el7_0.x86_64

How reproducible:

Deterministic.

Steps to Reproduce:
1. Install 389-ds-base.
2. Check /etc/group and /etc/passwd for dirsrv.

Actual results:

It's not there.

Expected results:

It should be there.

The pkiuser bugzilla is bug 1143067.
Comment 3 Jan Pazdziora (Red Hat) 2014-09-23 10:32:44 UTC 
For the record, the guidelines for allocating uids/gids and creating the system users are at https://fedoraproject.org/wiki/Packaging:UsersAndGroups#Soft_static_allocation
Comment 4 Jan Pazdziora (Red Hat) 2014-09-24 08:52:58 UTC 
Per the guidelines, changing the summary/proposal to %pre.
Comment 5 Jan Pazdziora (Red Hat) 2014-12-04 13:59:31 UTC 
If we are going to do this, it would be good to negotiate some uid/gid values with setup maintainers. Do we want to open some bugzillas for that?

I'd like to know if the uid 389 I mention above and which I plan to use for FreeIPA in containers is likely to be used.

Yes.

I don't know.  We'll have to to some research to find out of uidnumber/gidnumber 389 is reserved.

It does not seem to be reserved:

# grep 389 /usr/share/doc/setup/uidgid | wc -l
0
# rpm -qf /usr/share/doc/setup/uidgid
setup-2.9.0-2.fc21.noarch

Since the ticket was closed with "nothing to do", there's no much we can do in 389?

Not really. I'd still like that addressed, albeit without the fpc group assigning a particular value.

Then what exactly can we do in 389?  Change our spec files to do the useradd/groupadd with the value "389"?

Right, that's how I'd address it.

Ok, but what do we do when 389 is already in use by another user/group?

I can see two options: 1) just use the 389 value anyway; 2) invoke useradd without the -u 389.

Comment 24 Viktor Ashirov 2016-06-28 09:08:44 UTC 
Build tested:
389-ds-base-1.3.5.8-1.el7.x86_64

[1] Before the install:
# grep '389\|dirsrv' /etc/passwd /etc/group -c
/etc/passwd:0
/etc/group:0

[2] After the install:
# grep '389\|dirsrv' /etc/passwd /etc/group 
/etc/passwd:dirsrv:x:389:389:389-ds-base:/usr/share/dirsrv:/sbin/nologin
/etc/group:dirsrv:x:389:

[3] If dirsrv user already exists with different UID:
# grep '389\|dirsrv' /etc/passwd /etc/group 
/etc/passwd:dirsrv:x:636:636:389-ds-base:/usr/share/dirsrv:/sbin/nologin
/etc/group:dirsrv:x:636:

389-ds-base installs and setup-ds.pl correctly uses disrv user by default:

# setup-ds.pl
...
==============================================================================
The server must run as a specific user in a specific group.
It is strongly recommended that this user should have no privileges
on the computer (i.e. a non-root user).  The setup procedure
will give this user/group some permissions in specific paths/files
to perform server-specific operations.

If you have not yet created a user and group for the server,
create this user and group using your native operating
system utilities.

System User [dirsrv]: 
System Group [dirsrv]: 

==============================================================================
...

[4] If UID is already taken by different user:
# grep '389\|dirsrv' /etc/passwd /etc/group 
/etc/passwd:dirsrv1:x:389:389:389-ds-base:/usr/share/dirsrv:/sbin/nologin
/etc/passwd:xdirsrv:x:390:390:389-ds-base:/usr/share/dirsrv:/sbin/nologin
/etc/passwd:dirsrv:x:391:391:389-ds-base:/usr/share/dirsrv:/sbin/nologin
/etc/group:dirsrv1:x:389:
/etc/group:xdirsrv:x:390:
/etc/group:dirsrv:x:391:

Marking as VERIFIED.
