Auto cleanup old enrolled hosts
by Russ Long
We're adding FreeIPA to an immutable, often rotated environment (AWS ECS Hosts). These hosts are spun up and down at least daily. Is there a way to check FreeIPA to see when a host has last communicated with the FreeIPA Cluster? I'd like to use this information to auto-delete hosts that have not reported in from the FreeIPA host list.

certgmonger not able to renew a certificate: 2100 (Insufficient access: SASL(-1): generic failure: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (Credential cache is empty)).

Hi folks, I've got a machine where certmonger is unable to renew a

On the server side, I'm unable to find any errors being logged anywhere.
Even after I set 'debug = true' in /etc/ipa/default.conf & restarted

... which show that the API call was successful. On the other hand,
according to 'ipa cert-find --subject=xoanon.ipa.example.com', no
certificates have been issued.
It looks like the API isn't calling out to PKI/Dogtag, since nothing is
logged to /var/log/pki/pki-tomcat/localhost_access_log.*.txt or
/var/log/pki/pki-tomcat/ca/debug.*.log.
I also looked for AVC denials and didn't see anything in /var/log/audit.
So, back to the client. certmonger logs the following:

I found that I could add 'OPTS=-d9' to /etc/sysconfig/certmonger &
restart certmonger.service, which does cause it to log more, but it
doesn't give any further insight into the messages exchanged with the
server.
Does anyone know where I can look next?

New plugin almost ready - postfixadmin
by Francis Augusto Medeiros-Logeay
Hi,
I have almost finished a plugin for FreeIPA, so that admins can have similar functionality found on Postfix Admin.
https://github.com/oculos/freeipa-postfixadmin/blob/main/README.md
freeipa-postfixadmin/README.md at main · oculos/freeipa-postfixadmin
github.com
There is already a good plugin that does a bit of that, but the goal is a bit different. My main goal is not to mix up postfix configuration with groups and hosts, but have separate entities for domain, aliases and virtual domains, in addition to mailboxes.
It was written mostly to allow me to migrate my mailboxes from MySQL to FreeIPA, and I don’t have a huge postfix configuration - I only have multiple domains, mailboxes, aliases and virtual domains, so that’s the functionality I wanted with this plugin.
There are a few things missing before this can go in production («production» here means to actually migrate my mailboxes to FreeIPA), adding a mailbox to ipa users on the gui being the most important one.
I would appreciate any comments and feedbacks regarding this plugin. It wasn’t easy to understand the logic on how to write one, but I got the hang of it (for simple stuff).
Best,
Francis

Allow sysaccount to view its own entry
by Adam Bishop
I have a piece of software that tries to look up its own uid to check that LDAP is correctly configured.
This check fails because the sysaccount cannot view anything under cn=etc,cn=sysaccounts.
Is there an existing permission/privilege that I can use to allow it to read the sysaccounts tree (or better, just its own entry)?
Many Thanks,
Adam Bishop

Ok, let's try differently. Can you provide output of

This one is definitely not configured to handle SIDs. Also, see my

You have a range that defines UID/GID space of [1000...5000] but IDs are
outside this range. This is pretty much wrong regardless of whether we
enforce SIDs or not ;)
You need to create a separate ID range that would cover your existing
IDs. Before that, we need to create a configuration to be used for SID
generation -- if the ldapsearch above would show us that the entry in
cn=ad,cn=etc,$SUFFIX does not exist.
Since ipa-enable-sid has failed, probably the entry indeed does not exist and
it would be easier to construct it with ipa-ldap-updater tool:
----
dn: cn=${DOMAIN},cn=ad,cn=etc,${SUFFIX}
default:objectClass: ipaNTDomainAttrs
default:objectClass: nsContainer
default:objectClass: top
default:cn: ${DOMAIN}
default:ipaNTFlatName: NETBIOSNAME
default:ipaNTSecurityIdentifier: S-1-5-21-3777974847-1414448952-306354440
default:ipaNTDomainGUID: 529fcbe9-3e34-3122-a541-6786236014c1
default:ipaNTFallbackPrimaryGroup: cn=Default SMB Group,cn=groups,cn=accounts,${SUFFIX}
----
Change 'NETBIOSNAME' above to some name. By default that would be a
first part of your Kerberos realm, e.g. for IPA1.TEST that would be
IPA.
The SID value (S-1-5-21-...) is the one that your admin user has,
without the last part (relative identifier, RID, which is -500 for
administrator case).
Save this to a file named '90-somefile.update' and run as root
# ipa-ldap-updater ./90-somefile.update

Apache Tomcat Showing on Security Scan as Outdated.
by Marcelo Carvalho
Hi everyone.
We are running FreeIPA version:
VERSION: 4.10.1, API_VERSION: 2.251
Tomcat showing running is:
[root@corp-freeipa-01 tomcat]# java -cp catalina.jar org.apache.catalina.util.ServerInfo
Server version: Apache Tomcat/9.0.50
Server built: Jan 8 1970 23:12:05 UTC
Server number: 9.0.50.0
OS Name: Linux
OS Version: 5.14.0-284.30.1.el9_2.x86_64
Architecture: amd64
JVM Version: 11.0.20+8-LTS
JVM Vendor: Red Hat, Inc.
Host is a RHEL 9.2 with OS recently updated.
The Tomcat version is showing in our Security scan as outdated.
Is there a way to only update Tomcat or should I update FreeIPA using......
# ipa-ldap-updater --upgrade
# ipa-upgradeconfig
..... and expect the Tomcat gets updated?
Please advise.
Many thanks in advance.

FreeIPA server + Replica - HBAC rules not matching
by Finn Fysj
I'm setting up a server + replica and I've migrated data from an old IPA server using ipa migrate-ds.
I experience problems with SSH into my IPA servers, even though I have HBAC rules to allow this:
$ssh test_alice(a)ipa-test.example.com -i test_alice
Connection closed by 192.168.10.24 port 22
$ssh test_alice(a)ipa-test.example.com

Previsouly using FreeIPA I have been able to find "denying access" in log files because of not matching HBAC rules. Now I can't find any trace of this, even with debug_level = 10 in /etc/sssd/sssd.conf (domain, ssh, pam, sssd section).

Httpd Graceful restart - syntax error
by Finn Fysj
This morning I woke up to following:
[pid 18582] AH00171: Graceful restart requested, doing restart
httpd: Syntax error on line 56 of /etc/httpd/conf/httpd.conf: Syntax error on line 1 of /etc/httpd/conf.modules.d/10-nss.conf: Cannot load modules/libmodnss.so into server: /lib64/libnssutil3.so: version `NSSUTIL_3.82' not found (required by /lib64/libnss3.so)
cat /etc/httpd/conf.modules.d/10-nss.conf:
LoadModule nss_module modules/libmodnss.so
I've verified the files exists, after a manually restart of Httpd it was back.
httpd -t reports syntax OK

FreeIPA running in Kubernetes
by Jay Smith
It is possible to run FreeIPA in a Kubernetes cluster as a Pod?
If Yes. It is a good idea?
I'm new in Kubernetes. I'm currently running FreeIPA as a docker container and it's working very well. The problem in K8s is, there's no fix IP address and the privileged permission could be a problem.
