Problem running IPA client on IPv6 only connection
by William Muriithi
Hello,
I have an IPA clients that has both IPv4 and IPv6 addresses. One of the
IPA client is in the office and hence can reach the IPA server on both IPv4
and IPv6. However, the client outside the LAN can only reach the IPA server
over IPv6.
I was able to enroll the external client fine over IPv6 and from the logs,
all clean. However, when I attempted to ssh, its not able to retreave the
user from IPA. The client in the office works fine. I can also make for
example LDAP queries and they work over IPv6 fine. It looks like kerberos
is somehow however using IPv4. I reached this conclusion after taking a
tcpdump when attempting to ssh to the server and the kerberos traffic from
the client to IPA is on IPv4.
What would I need to do on the IPA client for it to prefer IPv6? I am
aware I could remove IPv4 address from DNS, but that would break any
communication from IPv4 only systems. Any assistance would be appreaciated.

IPA CA allow CSR SAN names in external domains
by Steve Dainard
Hello
I have a RHEL7 IPA server installed as a subordinate CA. I'd like to be
able to add SAN's for a different dns domain than exists in the IPA realm.
The dns for 'otherdomain.com' is handled by active directory which my IPA
server has a cross-forest trust with.
ie:
host: client1.ipadomain.com
certificate: CN = client1.ipadomain.com, SAN = client1.ipadomain.com,
servicename.otherdomain.com
When I try to submit this CSR with 'ipa-getcert request' the IPA server
denies with: "The service principal for subject alt name
servicename.otherdomain.com in certificate request does not exist"
It seems that the default CAACL enforces a profile named
'caIPAserviceCert', but I'm having some trouble determining what can be
modified (or cloned and changed in a new profile) that would allow the CA
to sign a CSR that contains *.ipadomain.com and *.otherdomain.com in the
SAN.
This is the only section in the profile that contains SAN:
policyset.serverCertSet.12.constraint.class_id=noConstraintImpl
policyset.serverCertSet.12.constraint.name=No Constraint
policyset.serverCertSet.12.default.class_id=commonNameToSANDefaultImpl
policyset.serverCertSet.12.default.name=Copy Common Name to Subject
Alternative Name
Thanks,
Steve

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.

Cannot add externally-signed IPA CA certificate
by Dmitry Perets
Hi,
I am trying to configure FreeIPA as a SubCA, and the "RootCA" is self-made with openssl. So I've signed the FreeIPA's request with my self-signed "root ca" certificate, but it looks like FreeIPA doesn't like it:
ipa-server-install --external-cert-file=/root/rootca/rootcacert.pem --external-cert-file=/root/rootca/certs/ipacert.pem
<...skipped...>
ipa.ipapython.install.cli.install_tool(CompatServerMasterInstall): ERROR CA certificate CN=RootCA,OU=PRJ,O=COMPANY,L=Bonn,C=DE in /root/rootca/rootcacert.pem, /root/rootca/certs/ipacert.pem is not valid: not a CA certificate
ipa.ipapython.install.cli.install_tool(CompatServerMasterInstall): ERROR The ipa-server-install command failed. See /var/log/ipaserver-install.log for more information
The subj above is my self-made root CA cert, so it looks like something is missing in it. But what...?
Here is it below, it has the "Basic Constraint" set with CA:TRUE... What else is required, so that FreeIPA accepts it as a root CA?
Should I add it somewhere first, before running the ipa-server-install?
[root@ipa ~]# openssl x509 -text -noout -in /root/rootca/rootcacert.pem

ipa-replica-install failing
by Mitchell Smith
Hi list,
I wanted to repost this issue with a more appropriate subject line, in
case anyone has come across this issue before and has a work around.
To provide some context, I have two FreeIPA instances running FreeIPA
4.3.1 on Ubuntu 16.04 LTS.
I want to migrate to FreeIPA 4.5.4 running on CentOS 7.
I have a way to migrate by dumping all the users out with ldapsearch
and adding them to the new instance with ldapadd but it is a bit messy
and will result in all users having to reset their password, as it
won't let me add in already encrypted passwords.
My initial thought was to add the new instance as a replica and then
eventually retire the old one.
I ran in to some problems with the ‘ipa-replica-install’ command though.
I was able to join as a client no problem, but when I went to run
‘ipa-replica-install’ it failed while configuring the directory server
component.
[25/42]: restarting directory server
[26/42]: creating DS keytab
[27/42]: ignore time skew for initial replication
[28/42]: setting up initial replication
[error] DatabaseError: Server is unwilling to perform: modification
of attribute nsds5replicareleasetimeout is not allowed in replica
entry
Your system may be partly configured.
Run /usr/sbin/ipa-server-install --uninstall to clean up.
I thought this might have something to do with differences between
4.3.1 and 4.5.4 but I wasn’t entirely sure.
If there is a work around for this issue, it would be a significantly
easier transition to the new FreeIPA instance.
Cheers,
Mitch

kinit -n asking for password on clients
by John Ratliff
When trying to do pkinit, if I do kinit -n on one of the IdM servers, it
works fine. If I try on a client machine, it asks me for the password
for WELLKNOWN/ANONYMOUS@REALM.
I have the pkinit_anchors setup for the realm. As I'm trying to do
anonymous pkinit, I think I don't need a client certificate.
On the server, I get this:

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 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
