Password authentication fails for AD users on some systems
by Ronald Wimmer 19 Jan '21

19 Jan '21

On some systems I cannot login using the password-based method. I see a pam_sss authentication failure (Permission denied). Using a valid kerberos ticket for login works. (The same user works password-based on other systems.) What could possibly be the problem? Cheers, Ronald

login to host issue
by Patterson, David 18 Jan '21

18 Jan '21

Hello, IPA version 4.6.8. Got a host that doesn't allow user logins, but was joined at some point to the domain. Everything that I can think of to check appears to be working Log into client system with local credentials Logs show invalid user attempts Client Keytab looks valid.....do these ever expire? Ktutil read_kt /etc/krb5.keytab list Shows the host/hostname.domain Quit Cannot 'id admin' or 'id' any other user Can obtain Kerberos keys for admin Can run ipa user-show for any user System appears valid in idmweb gui What did I miss? Get a new keytab for the client with ipa-getkeytab? Is there some server/client certs I should be checking? Thanks! David Patterson

A Couple Admin Quality of Life Tools
by Noah Bliss 18 Jan '21

18 Jan '21

Hey all, Just wanted to share a couple of tools I whipped up to flesh out some of the more time consuming or lean feature areas of FreeIPA. Hopefully they help you! Pull Reuquests and Issues are welcome. https://github.com/noahbliss/freeipa-sam FreeIPA-SAM is a simple menu-driven bash script for lifecycle management of system (service) accounts in LDAP. As a refresher, these seem to be the accounts you use as connectors to various services, but not for typical human user login. As there doesn't seem to be a convenient way to manage these in the WebUI and consistency is key when doing manual account management, I've found this to be a huge time-saver. https://github.com/noahbliss/freeipa-pen FreeIPA-PEN is a bash script designed to be installed on an IPA server and invoked by cron. It uses a system account to check LDAP and notify users via email if their password is going to expire soon. For accounts that do not have an email address or have already expired, it can generate a weekly/monthly report for you as an admin. Best regards, Noah

ipa-client-install Behind TLS Proxy
by Robert Gabriel 16 Jan '21

16 Jan '21

Hi, Is it possible to enrol a host using `ipa-client-install` behind a TLS proxy? I need to enrol hosts that can only reach `my.proxy.host:443` due to networking constraints. I see there is MS-KKDCP for kinit, kpasswd etc. We don't have much need for Kerberos ATM and are mainly using user, group lookups along with SSH pubkeys and Sudo rules. I'm assuming that at the very least we are using 389/636 for the above lookups? Then you would at least have to proxy your LDAPS? I have not done a `tcpdump` yet to ascertain what ports are in use. Thank you.

Trusting an AD synchronized towards Azure AD
by Monkey Bizness 15 Jan '21

15 Jan '21

Hi all, I have seen that FreeIPA can't integrate with Azure AD directly. Which is not that surprising from what I understand of it's internals. In the case of a trust with a local AD that is itself synchronized with azure, would it work? My instinct tells me it should but anything could happen behind the seen. Unfortunately, the guys handling azure/ad won't provide a test system to check it out to I'm asking here. Follow up question, any plans to support OpenID connect or SAML for user auth?

ipa-replica-install fails when the forwarder address is a link-local IP address
by Ganesh Kumar 15 Jan '21

15 Jan '21

Hi, I am setting up a 2 node FreeIPA system. One primary and the other is a replica. I want the replica to use the cloud DNS nameserver as a forwarder. In Google cloud, 169.254.169.254 is the nameserver. But when this is used as a forwarder I get the following error, ipa-replica-install: error: option --forwarder: invalid IP address 169.254.169.254: cannot use link-local IP address 169.254.169.254 Google Cloud does not provide a global DNS name resolver. Anyone knows why ipa is unhappy about link-local IP address? The closest explanation I could find is here https://pagure.io/freeipa/issue/6296#comment-327224, but I am unable to understand the context of it. Thanks, Ganesh

They are two sides of the same coin. You have an unknown certificate request being tracked by certmonger. In this case the nickname host/idm2.X.Y in /etc/pki/nssdb. Looks like there isn't a nickname with this value in that NSS database which explains the first error. I suspect that someone did some manual tracking changes and got this one wrong. It isn't something that IPA would have configured. Is it safe to delete this tracking request? Probably. But I'd double and triple check before doing so. Its unclear what the original purpose of creating it was. rob

is it possible to create a bind account with the 'ipa user-add' ?
by Rob Verduijn 12 Jan '21

12 Jan '21

Hello, I am looking into integrating a 3rd party application with ipa. Last time I checked it was only possible to do this with a bind account that you would create with an ldiff ldapmodify -x -D 'cn=Directory Manager' -W <<EOF dn: uid=mybindaccount,cn=sysaccounts,cn=etc,dc=lab,dc=example,dc=net changetype: add objectclass: account objectclass: simplesecurityobject uid: system userPassword: qwerty123 passwordExpirationTime: 20380101000000Z nsIdleTimeout: 0 EOF Is still the recommended way to go ? Or is there an option to do this with the 'ipa user-add' command ? Rob

problem with AD user login
by Suchismita Panda 12 Jan '21

12 Jan '21

Hi, We have a pair of FreeIPA servers (1 master and 1 replica) Freeipa server version 4.6.8 Recently when we are trying to enroll any new freeipa client to the server, the installation goes successful, but AD user login does not work. Even the client fails to retrieve AD user information using id command. This works fine on the FreeIPA server. Freeipa local user login is working fine on the client. There are other FreeIPA clients, where the AD user login is working fine. We generally use Ansible to join FreeIPA. So the installation process is also the same for all servers. Not sure why, recently it does not work. Any advice would be really helpful. Freeipa client version 4.8.6 In the logs mostly I am seeing below error - [ipa_s2n_get_user_done] (0x0040): s2n exop request failed. Thanks Suchi
