Reenrolling IPA client in split-brain environment
by William Faulk
I have an IdM environment where one of the replicas stopped replicating out. A number of clients were enrolled into this replica. They are currently working fine, since they're basically only ever talking to that replica. But I need to fix that replica, and the only feasible solution at this point seems to be a re-initialization. But that means that these clients' enrollments will disappear.
Is there any way to get a client in this state to re-enroll into a different replica that doesn't yet know about it, in such a way that it won't have an interruption in the IdM services it consumes? I only have four systems in this state, so I can reasonably make manual changes to support this, as long as they won't be snowflakes in the long term.

freeipa.py plugin for AWX dynamic inventory not available
by slek kus
Hi, is there a possibility to have the below plugin avialable in Ansible Galaxy FreeIPA collection?
https://github.com/ansible/ansible/blob/stable-2.9/contrib/inventory/free...
Trying to use dynamic inventory by using the plugin. but this is not being included/downloaded with the collection.
I create a dynamic inventory (sourced from project, a git where I have the following folder and file):
inventories/clients_and_controllers.yml, where the contents of the .yml is a single line:
```
plugin: freeipa
```
The collections used are:
```
collections:
- name: freeipa.ansible_freeipa
- name: community.general
```
The error message trying to sync the resource for the dynamic inventory is:
[WARNING]: * Failed to parse
/runner/project/inventories/clients_and_controllers.yml with auto plugin:
inventory config ‘/runner/project/inventories/clients_and_controllers.yml
’
specifies unknown plugin ‘freeipa.py’
Kind regards!

Is there a limitation with clients newer than the server?
What can I check to fix this issue?

LDAP conflicts after yum update on Almalinux 8.9
by Lee Csk
After performing a usual Yum update's on multiple IPA servers (not at the same time, one server reportedly started hanging), we started observing "LDAP Conflicts" in multiple IPA replication servers:
az2-replica.noc.net
| LDAP Conflicts | 9 | FAIL |
mi2-replica.noc.net:

mi1-replica.noc.net:

| LDAP Conflicts | 3 | FAIL |
sg2-replica.noc.net
| LDAP Conflicts | 3 | FAIL |
The "Replication status" while reports OK, we observe also flapping at times between OK and FAIL too.
We have tried to follow on one of the replication servers: https://access.redhat.com/documentation/en-us/red_hat_directory_server/11...
- by removing the orphan entry, however the replication broke completely on it (ipa service couldn't start back up), requiring a full re-install of that specific replica.

Howto: Migrate DNS/DNSSec off freeipa
by Harry G Coin
If you've decided freeipa's DNS and/or DNSsec isn't part of your future,
here's a way to migrate to another solution without disrupting the rest
of freeipa's capabilities. I couldn't find any documentation about how
to do this in an automated way, this worked for me. (Watch someone
answer this post with 'oh, you just run X and it's all automated!)
This same instruction set can help whenever it's necessary to reinstall
a freeipa-master on a fresh/new system.
Corrections welcome! This is based on experience and with hints posted
at
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/...
It requires a currently running master and at the ability to install (or
re-install) one replica.
1. Review the logs on the master to make sure operations are normal
(you can ignore dns/dnssec related errors). Before making changes: in
case it all goes horribly wrong make a complete snapshot of the master
and save it (usually best done as a low-level disk operation when the
master host is powered off).
2. On the master: Make sure whatever is replacing freeipa's DNS/DNSsec
is operational and has satisfactory content. (We chose Technitium,
after adding failover capability to it). To gain confidence that is
complete, point /etc/resolv.conf on the master at the new DNS server,
then run ipa-healthcheck until there are no complaints. Zone transfer
can be your friend.
3. Create a new system/vm and on it install a replica
(ipa-replica-install) but do not include --setup-dns or related options
like --no-forwarders. Comprehend the details of 'ipa-replica-manage
dnarange-set' which may be necessary on your master and different on
your replica. This replica can be temporary, in that case do not
specify a large dnarange.
4. On the replica, point /etc/resolv.conf to the new dns server, then
run ipa-healthcheck to make sure there are no complaints.
5. On the replica, kinit admin then: ipa config-mod
--ca-renewal-master-server <replica fqdn> . From
/etc/pki/pki-tomcat/ca/CS.cfg remove 'ca.certStatusUpdateInterval=0'
Then ipactl restart on the replica.
6. Add 'ca.certStatusUpdateInterval=0' to
/etc/pki/pki-tomcat/ca/CS.cfg on the soon-to-be-retired master. ipactl
restart on the master.
7. On the master, ipa-crlgen-manage disable and on the replica
ipa-crlgen-manage enable.
8. check that ipa-crlgen-manage status on the master shows disabled,
and on the replica shows enabled.
9. Power down the master. Check that the replica is operating
normally and new DNS operations are normal.
10. On the replica, do 'ipa-replica-manage del <master fqdn> --force
(you will be warned about dns, but you've got that covered, right?)
11. Install a new OS or reformat what was the master. Make sure DNS
is correct on the new setup. Install ipa-server as if on a replica,
pointing at the temporary replica you've created above as the source.
Remember NOT to include --setup-dns or dns related installation options.
12. Reverse steps 7, 6 and 5.
13. On the master, you may need to run step 3 with the prior dna-range.
14. When 'ipa-healthcheck' on the now-new master reports no errors, if
you wish you can delete the replica from the ipa topology and retire
that system.
That's it! The good news is adding freeipa's DNS back into the mix if
that becomes best in your setup is well documented. Some of the
alternative DNS servers can act as secondary servers then 'promote'
themselves to 'primary' using the transferred database, which makes
migration easier. If you use DNSSec, be sure to add DS records for the
new nameserver in your registrar's dns before retiring
bind9-named-pkcs11/softhsm/opendnssec/bind-dynldap and related freeipa
DNS suite subsystems.
We found a way to keep the tight relationship between freeipa and DNS
(host DNS records and the like). To make that a 'native' freeipa
option, you might imagine a freeipa plugin that issued host zone record
related commands to third-party DNS solutions.

Fedora 40: new warning in ipa-healthckeck
by Jochen Kellner
Hi,
I've upgraded my freeipa server to Fedora 40 (the system was installed
several releases ago). After the upgrade I get the following new warning
from ipa-healthcheck:
{
"source": "ipahealthcheck.ds.backends",
"check": "BackendsCheck",
"result": "WARNING",
"uuid": "875db8e3-029c-46f7-87e5-bf9a216d9637",

"nsslapd-db-private-import-mem",
"nsslapd-db-deadlock-policy"
],
"msg": "Found configuration attributes that are not applicable for the configured backend type."
}
},
According to
https://www.port389.org/docs/389ds/FAQ/Berkeley-DB-deprecation.html the
bdb backend is deprecated. The system was installed with
389-ds-base < 1.4.4.9-1.fc33.x86_64 (I see the upgrade to that version
in /var/log/dnf.rpm.log*. Since 3.0 new installations should use LMBD as
the backend. Is that true for new installations?
What is the desired action that I should take?
I can remove the options from the dirsrv configuration. Should I?
Shall I switch to lmdb manually? Or is that something that
ipa-server-upgrade should be doing?
Otherwise I can suppress the message in ipa-healthcheck for now. But I
guess I should fix my installation before the deprecated support really
gets dropped... Is deploying a new replica and decommisioning the old
server we the preferred action?

IPA replica cannot lookup AD trust users (worked before)
by slek kus
Hi, the only replica cannot retrieve AD trust users (one way trust). Trust agent had been installed on this replica.
I noticed this issue, since clients that point to the replica started to fail authenticating users. This replica worked OK before.
All functions and syncs except for the AD user lookup. overrides are synced over but replica cannot find the user.
Can't get it fixed. Is this repairable? Can I uninstall the replica and reinstall?
[root@idm01 ~]# ipa server-role-find
-----------------------
10 server roles matched
-----------------------
Server name: idm01.linux.redacted.domain
Role name: AD trust agent
Role status: enabled
Server name: idm02.linux.redacted.domain
Role name: AD trust agent
Role status: enabled
Server name: idm01.linux.redacted.domain
Role name: AD trust controller
Role status: enabled
Server name: idm02.linux.redacted.domain
Role name: AD trust controller
Role status: enabled
<...>
On the main server, the AD user can be looked up. On the "replica" it returns empty.
working on main server:
[root@idm01 ~]# getent passwd testuser(a)subdoma.redacted.domain
testuser@subdomA.redacted.domain:*:683005154:683005154:CHANGED:/home/testuser:/usr/bin/bash
Checking the sssd_doamin.log of the replica, I see the message that the domain is not active while fetching ad user. Further in the same log there's mention of another subdomain be inactive.
The trust is wirth a AD forest with 2 subdomains.

Hi,
so pam_sss.so is not called at all which would explain the behavior. I
assume pam_sss.so is listed in common-auth. Did you add it on your own
to common-auth or was it added by a system utility e.g. pam-auth-update?

autofs freezes system after update to F40.
by Albert Szostkiewicz
Yesterday I've upgraded F38-F49, all went fine, no issues. Today I tried F39-f40 and system freezes on autofs. Got some sssd errors, and i assume it might be all related (?).
There are no errors from autofs side itself, only warning:
"autofs.service: Referenced but unset environment variable evaluates to an empty string: OPTIONS"
. As soon as I enable autofs, all system is frozen (although my nfs mounts are set to 'soft').
I am getting those errors, which I have reported here (https://github.com/SSSD/sssd/issues/7314) as I saw something similar being reported year ago:

Error adding cross trust between FreeIPA and Zentyal (Samba)
by Joyce Babu
I am trying to setup cross trust between IPA and Samba. When I try to run
ipa trust-add --type=ad ad.example.org --admin Administrator --password --range-type=ipa-ad-trust
The command aborts with error
ipa: ERROR: CIFS server communication error: code "3221225473", message "{Operation Failed} The requested operation was unsuccessful." (both may be "None")
Samba log on the Zentyal server has the following error message
Kerberos: Client (Administrator(a)AD.EXAMPLE.ORG) from ipv4:10.15.5.2:41504 has no common enctypes with KDC to use for the session key
