IPA and legacy systems
by Ronald Wimmer
What would be a good solution to add systems where the FQDN cannot be
changed?
Would it make sense to add a second DNS A Record in the IPA domain for
each of these systems?
Is there any experience on how to deal with such a situation?
Thanks a lot in advance!
Cheers,
Ronald

freeipa with sudo and 2FA (OTP)
by John Ratliff
I'm trying to setup freeipa with OTP. I created a TOTP under my user in
freeipa and updated my user to use 2FA (password + OTP).
When I try to do sudo, it only asks for my password and it fails every
time (presumably because it isn't getting the OTP first).
I didn't see anything useful in the sss_sudo logs, even after adding
debug_level = 6 in the config.
What can I do to further troubleshoot this?
Thanks.

Vault: Cannot authenticate agent with certificate

Can login with non-existing user
by Ronald Wimmer
I have managed to login to an IPA client with a non-existing user.
My AD user is z123456(a)addomain.mydomain.at and I have created a similar
user called i123456(a)ipadomain.mydomain.at. What happened now is that I
could log in with the i-User and what I get to see after logging in is this:
[i123456@addomain.mydomain.at(a)as12314 ~]$ id
uid=1246600007(i123456(a)addomain.mydomain.at)
gid=1246600007(i123456(a)addomain.mydomain.at)
groups=1246600007(i123456@addomain.mydomain.at),1246600016(my-ad-group(a)ipadomain.mydomain.at)
context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
[i123456@addomain.mydomain.at(a)as12314 ~]$ whoami
i123456(a)addomain.mydomain.at
The user i123456(a)addomain.mydomain.at does NOT exist.
addomain is set as default domain in the client's sssd.conf.
What is wrong here? Are things just displayed wrong or could it be more?
Which files do you need in order to analyze this issue?

FreeIPA v4.5.0 install lost topology suffixes
by Gavin Williams
Afternoon all
I’ve got a slightly strange one with one of our FreeIPA clusters, whereby the topology suffixes appear to have disappeared.
From what I can see, this is causing replication issues between the hosts, which is causing us issues with bootstrapping new clients against FreeIPA.
I’m not aware of any config changes that have happened on the FreeIPA hosts that could have caused this issue, so am a bit stumped atm.
Is someone able to advise next steps on how to investigate the cause and correct the configuration?
Regards

Automounting homeshares partially stopped working
by Ronald Wimmer
Some days ago a strange problem struck us. When colleagues access a
server using an ipa-automounted share from a Windows client they can
logon to such a server using a Kerberos ticket but they cannot access
their NFS-automounted home-share anymore. When they log on with
username/password they can.
When I try the same from my linux client I do not encounter any problems
(using the same users as in the above scenario).
Where should I start digging in order to find out what is going wrong?
Cheers,
Ronald

Removing first freeipa master
by Jo Domsic
Hi to the good people of FreeIPA!
I'm in the process of removing old servers from my datacentar, and I was wondering if I can delete/remove (first created) freeipa server?
I have 4 masters:
[root@server] ipa-replica-manage list
freeipa03.lan: master
freeipa04.lan: master
freeipa01.lan: master <--- I want to delete this one
freeipa02.lan: master
What will happen to servers that have:
[root@server2] cat /etc/ipa/default.conf
#File modified by ipa-client-install
[global]
basedn = dc=lan
realm = LAN
domain = lan
server = freeipa01.lan
host = server2.lan
xmlrpc_uri = https://freeipa01.lan/ipa/xml
enable_ra = True

IPA with multiple legs: hostname resolution
by Dmitry Perets
Hi,
I'd like to ask for your advise for the following topology...
On a given site, IPA server has two legs (two NICs), let's call them "inside NIC" and "outside NIC".
The inside NIC subnet is local to the site. The outside NIC subnet is interconnecting sites.
All the local clients talk to IPA via the inside NIC. But to setup a replica on another site, we must reach IPA via outside NIC (the inside subnet is not routable beyond the local site boundaries).
So the question arises: how to configure proper DNS resolution for the hostname of the IPA server itself?
DNS is handled by IPA itself, fully in our control.
So we have two options:
1. We create two A records for the same IPA hostname, let's say "ipa.site1.example.com". But then not sure if it will work fine... Technically, two IPs for the same name means load-balancing, right? So will I have intermittent connectivity issues, because it will return inside and outside IP interchangebly?
2. We create a new DNS name, e.g. "ipa-outside-site1.example.com", for the outside IP, and manually add it to the @ entry of "example.com", so that wannabe-replica on the remote site can use that FQDN as its master IPA. Will this work fine..? Will it not cause issues to the local clients on site1, who must keep using IPA with inside IP? Will it not cause issues on IPA server itself for some reason?
Please share your experience on this!
Thanks.
