In the open source world everything lives/evolves/changes. This is why the new version of connecting latest FreeBSD 14.0-STABLE system to the FreeIPA/IDM is needed. One of the things that changed is that security/sssd is now deprecated and security/sssd2 is its successor. Also new version of ports-mgmt/poudriere-devel is available – with needed fixes already merged – and also with new restyled web interface.
I already messed with that topic several times in the past:
- Connect FreeBSD to FreeIPA/IDM
- Connect FreeBSD 13.2 to FreeIPA/IDM
- FreeBSD on FreeIPA/IDM with Poudriere Repo
This article will try to address and contain all steps needed – including setting up the FreeIPA/IDM server and including the Poudriere setup. Below You will find Table of Contents for this article. All of these systems will be Bhyve virtual machines.

- Summary
The FreeBSD project recently started to provide ZFS based VM images … but unfortunately only for 14.0-RELEASE and they are not created for 14.0-STABLE or 15-CURRENT versions – so we will use the UFS based ones for both Poudriere server and FreeBSD FreeIPA/IDM client. For the record – https://download.freebsd.org/snapshots/VM-IMAGES/14.0-STABLE/amd64/Latest/ – they are available here.
Some note about commands run in this article – different colors for various hosts.
host # top -ba -o res 3 // executed on the host system [root@idm ~]# yum update -y // executed on IDM server root@freebsd:~ # geom disk list // executed on Poudriere server root@poudriere-devel-14-stable:~ # poudriere ports -l Β // executed on Poudriere server root@idm-client:~ # hostname idm-client.lab.org // executed on IDM client (FreeBSD) important information // marked as GREEN color
For the FreeIPA/IDM server I have used Alma Linux RHEL clone – but we know that Rocky Linux or Oracle Linux would also work well. We will use three systems in this article.
FreeIPA/IDM server – with idm.lab.org hostname.
OS: Alma Linux
IP: 10.0.0.200/24
GW: 10.0.0.1
domain: lab.org
realm: LAB.ORG
hostname: idm.lab.org
Poudriere builder system – with poudriere-devel-14-stable.lab.org hostname.
OS: FreeBSD 14.0-STABLE
IP: 10.0.0.124/24
GW: 10.0.0.1
DNS: 1.1.1.1
domain: -
realm: -
hostname: poudriere-devel-14-stable.lab.org
FreeBSD client for FreeIPA/IDM system – with idm-client.lab.org hostname.
OS: FreeBSD 14.0-STABLE
IP: 10.0.0.233/24
GW: 10.0.0.1
DNS: 10.0.0.200
domain: lab.org
realm: LAB.ORG
hostname: idm-client.lab.org
I really like the FreeBSD Bhyve memory ballooning – which means the guest VMs only take as much RAM as guest OS allocated and not 12 GB RAM as is configured.

As you can see I am using sysutils/vm-bhyve-devel for the Bhyve management – but You may as well use bare /usr/share/examples/bhyve/vmrun.sh instead … or even entirely different hypervisor like KVM on Linux or VirtualBox on Windows – it does not matter as long as machines have access to the Internet and they see each other in the same LAN network.
FreeIPA/IDM Server – Installation
I installed the Alma Linux some time ago – so the screenshot shows older 8.7 version.
After reboot its network is configured as shown below.
[root@idm ~]# cat /etc/sysconfig/network-scripts/ifcfg-enp0s3
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=none
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=no
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=eui64
NAME=enp0s3
UUID=120efe1f-3cb6-40cf-8aad-b17066c08543
DEVICE=enp0s3
ONBOOT=yes
IPADDR=10.0.0.200
PREFIX=24
GATEWAY=10.0.0.1
DNS1=1.1.1.1
IPV6_DISABLED=yes
Some more basic setup commands below.
[root@idm ~]# echo 10.0.0.200 idm.lab.org idm >> /etc/hosts [root@idm ~]# cat << EOF >> /etc/sysctl.conf # DISABLE IPv6 FOR MAIN enp0s3 INTERFACE net.ipv6.conf.enp0s3.disable_ipv6=1 EOF [root@idm ~]# hostnamectl set-hostname idm.lab.org [root@idm ~]# timedatectl set-timezone Europe/Warsaw [root@idm ~]# timedatectl set-local-rtc 0 [root@idm ~]# yum update -y [root@idm ~]# reboot

If you would like to see what a successful ipa-server-install(8) looks like – you can take a look HERE.
We have our FreeIPA/IDM server installed.
You will need to add 10.0.0.200 as idm.lab.org to your /etc/hosts on the system where you will be using the browser (or to your local DNS).
host # grep idm /etc/hosts
10.0.0.200 idm.lab.org idm
You can login to it typing https://10.0.0.200 at your local browser – you will be redirected to https://idm.lab.org/ipa/ui/ immediately and you will see the login page as shown below.
You may login with admin username and the password you specified for the ipa-server-install(8) command (or password if you just copy pasted that command π
FreeIPA/IDM Server – Configuration
… and after logging in I created a regular vermaden user as shown below.
Keep in mind to reset your password by connecting to FreeIPA/IDM server.
host # ssh -l vermaden 10.0.0.200 (vermaden@10.0.0.200) Password: (vermaden@10.0.0.200) Password expired. Change your password now. Current Password: (vermaden@10.0.0.200) New password: (vermaden@10.0.0.200) Retype new password: Last failed login: Wed Oct 19 00:47:57 CEST 2022 from 10.0.0.33 on ssh:notty There was 1 failed login attempt since the last successful login.

The more important configuration is in HBAC and Sudo rules.
Here are HBAC related settings.
… and the Sudo part.
Poudriere Server – Setup
One note for the FreeBSD setups below – please use /bin/sh shell (default for root since 14.0-RELEASE) for the commands … or zsh(1) for example … or other POSIX compatible shell. Some of these commands may not work properly on ‘C’ based shells or in fish(1) shell.
This is the template I used for Bhyve VMs.
host # cat /vm/.templates/freebsd.conf
loader="bhyveload"
cpu=1
memory=256M
network0_type="virtio-net"
network0_switch="public"
disk0_type="nvme"
disk0_name="disk0.img"
We will now create poudriere-devel-14-stable VM for Poudriere server.
host # vm create -t freebsd -s 20g -m 12g -c 8 poudriere-devel-14-stable host # du -sgA /vm/poudriere-devel-14-stable/* 20 /vm/poudriere-devel-14-stable/disk0.img 1 /vm/poudriere-devel-14-stable/poudriere-devel-14-stable.conf 1 /vm/poudriere-devel-14-stable/vm-bhyve.log
Now we will replace disk0.img with Latest FreeBSD 14.0-STABLE snapshot.
host # fetch -o - 'https://download.freebsd.org/snapshots/VM-IMAGES/14.0-STABLE/amd64/Latest/FreeBSD-14.0-STABLE-amd64.raw.xz' \ | xz -d > /vm/poudriere-devel-14-stable/disk0.img host # file -b /vm/poudriere-devel-14-stable/disk0.img DOS/MBR boot sector; partition 1 : ID=0xee, start-CHS (0x0,0,2), end-CHS (0x3ff,255,63), startsector 1, 12649684 sectors host # du -sgA /vm/poudriere-devel-14-stable/* 7 /vm/poudriere-devel-14-stable/disk0.img 1 /vm/poudriere-devel-14-stable/poudriere-devel-14-stable.conf 1 /vm/poudriere-devel-14-stable/vm-bhyve.log
We now need to add additional disk1.img disk to for ZFS pool.
host # truncate -s 10G /vm/poudriere-devel-14-stable/disk0.img host # vm add -d disk -t file -s 100g poudriere-devel-14-stable host # vm info poudriere-devel-14-stable | grep -A 16 virtual-disk virtual-disk number: 0 device-type: file emulation: nvme options: - system-path: /vm/poudriere-devel-14-stable/disk0.img bytes-size: 10737418240 (10.000G) bytes-used: 1720046592 (1.601G) virtual-disk number: 1 device-type: file emulation: nvme options: - system-path: /vm/poudriere-devel-14-stable/disk1.img bytes-size: 107374182400 (100.000G) bytes-used: 1024 (1.000K) host # du -sgA /vm/poudriere-devel-14-stable/* 10 /vm/poudriere-devel-14-stable/disk0.img 100 /vm/poudriere-devel-14-stable/disk1.img 1 /vm/poudriere-devel-14-stable/poudriere-devel-14-stable.conf 1 /vm/poudriere-devel-14-stable/vm-bhyve.log
Now internally inside VM.

Fortunately we do not need to patch ports-mgmt/poudriere-devel anymore as the -u flag for sort(1) is already there.

Poudriere Server – Build FreeIPA/IDM Client Packages
Now we will choose needed options for our FreeBSD Ports and then start the bulk process of fetching and building them.

This is how the Poudriere build process looks like from the terminal … and a view for its new ZFS datasets that Poudriere created.
It was 2nd or 3rd run so when You first will run the bulk there will be more information about fetching packages etc.
Below You can see what processes are running in htop(1) during the build.
You can also follow the status of the build process in the browser at https://10.0.0.124 page.
Generally the new Poudriere interface is quite ‘large’ I would say – so I use it at 70% scale/zoom on Firefox and IMHO its more usable like that.
And below are the details about our build job.
Poudriere Server – Update Repo/Packages
Everytime you will need to update the packages in that FreeIPA/IDM repo You will need to run these commands.
root@poudriere-devel-14-stable:~ # poudriere ports -u -p idm root@poudriere-devel-14-stable:~ # poudriere bulk -j 14-0-S-amd64 -b latest -p idm -f /usr/local/etc/poudriere.d/idm
You may as well update the FreeBSD Jail when needed.
root@poudriere-devel-14-stable:~ # poudriere jail -u -j 14-0-S-amd64
FreeBSD 14.0-STABLE Client – Setup
I will not repeat the process – but the same as with Poudriere server – you need to create FreeBSD client – for example as Bhyve VM.
Now – the needed configuration on FreeBSD 14.0-STABLE system to connect it to FreeIPA/IDM server.
root@idm-client:~ # :> ~/.hushlogin root@idm-client:~ # mkdir -p \ /usr/local/etc/ipa \ /var/log/sssd \ /var/run/sss/private \ /var/db/sss root@idm-client:~ # echo '10.0.0.233 idm-client.lab.org idm-client' >> /etc/hosts root@idm-client:~ # echo '10.0.0.200 idm.lab.org idm' >> /etc/hosts root@idm-client:~ # hostname idm-client.lab.org root@idm-client:~ # sysrc hostname=idm-client.lab.org root@idm-client:~ # fetch -o /usr/local/etc/ipa/ca.crt http://idm.lab.org/ipa/config/ca.crt
Now we will need to add or FreeBSD client to FreeIPA/IDM. Instructions below.

Should

be
“that security/sssd is NOW deprecated” ?

I’m also getting the error:
When running sssctl user-checks $user
I tried enabling D-Bus but then it just timeouts instead, did you experiment with this?
LikeLike
I did not investigated that as I assumed it is some small Linuxism – fortunately IMHO harmless as you can login and use sudo(8) with IDM credentials.

I think
root@idm-client:~ # fetch -o /usr/local/etc/ssl/certs/poudriere.cert http://idm.lab.org/data/poudriere.cert
should be
