How to prevent non-admin users of FreeIPA from reading the list of users in the web interface?
by cdknight
When a user signs in to FreeIPA, I do not want them to be able to view the list of users in my LDAP server under the "Active users" link. I still want them to be able to administer self-service, so they can reset their password, add OTP tokens, etc. How would I go about doing this? The users will only be able to access the web interface, so it doesn't matter whether they can access it from other sources.

kinit: KDC can't fulfill requested option while renewing credentials - which approach?
by Pieter Baele
I tried various approached to get Renewable tickets :
modifying the kdc
modifying krb5.conf
using kadmin.local on every replica to modify the principal; which is not
working - as designed (?)- in IPA
What should I do to get a ticket with the correct R flag from IPA ?
I don't think this is SSSD related (the service needing the renewable
ticket this way is Apache Storm)
Thanks a lot!

Do keytabs expire?
by Ronald Wimmer
Hi,
today I found out that some entries in a keytab file seemed to have expired:
Request ticket server HTTP/mwc.linux.mydomain.at(a)LINUX.MYDOMAIN.AT kvno
4 not found in keytab; keytab is likely out of date
Fetching the keytab again with ipa-getkeytab fixed the problem. But why
is this happening? Do keytab entries expire? I have not set any custom
password or ticket policies.
Regards,
Ronald

Removal & clean up certificates from o=ipaca
by David Goudet
Hello all,
I have to clean up lot of useless certificate in dirsrv database.
Because of resubmit loop on Certmonger client, i have 99,9% of certificate in dirsrv database that are useless and not obsolete (expiration in 2020) (it represent ~85 000 certificates).
These useless certificates produce some issues on FreeIPA:
- decrease FreeIPA performances on CLI and GUI
- increase the LDAP size
- increase size and time of FreeIPA backup
...
Is it possible to purge these certificates in dirsrv database and how?
I found two branches in LDAP directory about these certificates:
dn: cn=xxx,ou=ca,ou=requests,o=ipaca
dn: cn=yyy,ou=certificateRepository,ou=ca,o=ipaca
I can remove all requests and certificates entry from dirsrv database but how it is supported by PKI manager Dogtag (CRL, certificate generation, OCSP)?
(This topic has already been discuss on https://lists.fedorahosted.org/archives/list/freeipa-users@lists.fedoraho...)
Thank you for you help

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?

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:
