Enabling two-factor by host
by Aaron Hicks 17 Nov '17

17 Nov '17

Hello the list, Is it possible to enable two-factor authentication using Google Authenticator on FreeIPA on specific hosts or groups of hosts? Alternatively, are there any recommendations on modifying the Pam configuration on these 2FA required machines to grab the OTP token from FreeIPA when a user logs in? Regards, Aaron Get Outlook for iOS<https://aka.ms/o0ukef>

PWM and FreeIPA integration
by Aaron Hicks 16 Nov '17

16 Nov '17

Hello the FreeIPA List, So as using the FreeIPA API and using LDAP directly to set existing users passwords (because they don't yet have one) didn't work, we've set up PWM by mostly following this gist: https://gist.github.com/PowerWagon/d794a1233d7943f1614d2ae5223e678a This has worked, and users with existing passwords can log in an manage their passwords. We are not using it to create user accounts. However we have some users who do not have passwords, so they can't provide a current password to do a password change. We have a page on our customer management system that allows users with no password to enter a password and this is sent to the PWM REST interface to set the user's password in FreeIPA. The user is not new, they just have no password set. There's a couple of thousand of them, so we're really keen on self service. However when we send a password reset request to the PWM REST with the setpassword command (using the pwmproxy user credentials) we get the following response: {"error":true,"errorCode":5027,"errorMessage":"You do not have permission to perform the requested action."} We've tried making the pwmproxy user a admin, and have giving them permission to change users passwords with the System: Change User password permission, however this gives the same response. I'd prefer not to give the pwmproxy account admin, but we need this to work. We've also tried using the admin account with the same results, we'd prefer to use an API key but have not yet managed to authenticate with one. I'm asking here as PWM is recommended by FreeIPA as a suitable 3rd Party project https://www.freeipa.org/page/Self-Service_Password_Reset I feel we're one step away from making this work. Is there a specific permission, aci, or other hoop to jump through to allow PWM to set a user's password? Regards, Aaron Hicks

pointing SSSD/IPA at named AD domain controllers now with recent updates?
by Chris Dagdigian 16 Nov '17

16 Nov '17

The most fragile and user-angering aspect of our complex IPA setup in AWS is when user AD password checks mysteriously fail and deny login. All of the troubleshooting stuff works fine - user is recognized as valid, ipa hbactest all work fine but the user gets permission denied when logging in. Right now my only fix is converting users over to SSH keybased logins with the IPA server holding the public key -- that works great. Restarting sssd a few times and waiting 10 minutes also usually resolves the issue. We *suspect* the password check failure is because this large organization has 100+ domain controllers scattered in networks and datacenters all over the place and we think that maybe SSSD is DNS resolving via _SVR_ records a domain controller that is unreachable or unknown to our cloud nACLs and security controls -- or maybe a domain controller that just flat out refuses to talk to us. I've seen on this list mentions of really cool AD integration improvements like being able to have more than one AD domain vs the existing "Default domain" that requires our users to login with fully qualified <username>@<DOMAIN>.COMPANY.ORG as well as mentions that future versions of SSSD would allow us to pin our communication to known/named AD controllers? I think the basic advice from the IPA community was that this stuff was showing up in modern sssd releases and that we just had to wait a bit for the updated sssd code to show up in distro repos. Did I understand things correctly? Are we at the point now with IPA and SSD upgrades where we could possibly pin our AD traffic to named controllers? And maybe also address the AD domain search issue as well? Thanks! Chris

Can't sync a new replica, large db file,
by Mike Johnson 16 Nov '17

16 Nov '17

Hi I've got a small environment which had until recently 2 IPA servers. Both CentOS 7.4.1708 Version info: id1: Name : ipa-server Version : 4.5.0 Release : 21.el7.centos.2.2 Kernel: 3.10.0-693.5.2.el7.x86_64 389-ds-base is at version 1.3.6.1 id5: Name : ipa-server Version : 4.5.0 Release : 21.el7.centos.2.2 Kernel: 3.10.0-693.5.2.el7.x86_64 389-ds-base is at version 1.3.6.1 I recently had an issue with high IO/load, and noted that the following file: /var/lib/dirsrv/slapd-PROD-MYDOMAIN-COM/cldb/<long-filename>.db was huge (5GB-ish) in a very small 2-master environment. This is on the master. My understanding is that the entries in this file, which have timestamps from months ago, exist because of failed replication. I don't understand how to clear this without breaking things. Second issue; not sure if related: I've since lost the replica (id2) but I've prepared a new machine (id5) to be a new replica of id1. I've cleaned the RUVs and deleted the replication agreements but when I join the new machine to the existing one using `ipa-replica-install` then I get the following on the replica: ################ Starting replication, please wait until this has completed. Update in progress, 10 seconds elapsed [ldap://id1.prod.mydomain.com:389] reports: Update failed!

No luck. I'm also getting hundreds of the last line "different database generation ID" but my understanding is that this is only logged because the replica is yet to be set up. Would anyone please be able to provide some guidance? I've been at this for a few days now! Thanks! MIke

IPA & AD Domain Layout
by Justin Smith 16 Nov '17

16 Nov '17

I was tasked with setting up FreeIPA & Active Directory and connecting them with a trust relationship. On FreeIPA 4.5, I created ipa.companydomain.com, set up an internal DNS zone for companydomain.com (which my company has used for both internal and external DNS - a bad practice, I know), and then tried to establish a trust relationship with Active Directory 2016. No dice. Alexander B. on here told me that AD does not expect that a forest can have a TLN which is superior to AD forest's root domain. A Microsoft article on AD best practices recommends registering a public domain and then using a subdomain of that for internal purposes. That sounds sensible. Here's what I envision: companyname.com (external sites + external DNS) -> corp.companyname.com (FreeIPA + intranet DNS) -> ad.corp.companyname.com (Active Directory domain) Does that sound sensible? Just wanted to run it by someone else so I don't end up surprised again. --- Justin Smith IT Analyst MIM Software, Inc. [ https://www.mimsoftware.com/ | https://www.mimsoftware.com ]

FreeIPA server: Replication issues
by James Harrison 15 Nov '17

15 Nov '17

Hello,I am using Centos to host our FreeIPA servers. We have a CA-less setup. I have upgraded to Centos 7.4 and FreeIPA version : VERSION: 4.5.0, API_VERSION: 2.228 The upgrade of both went off without any seen errors. However, now I am getting the following messages on each server (12 in total): "ERR - attrlist_replace - attr_replace (nsslapd-referral" messages Firstly, are these messages real problems I need to deal with?Secondly, if they are problems, how do I fix them? I have searched the internet and found lots of confusing mail threads, but no howto style document. Thanks for any help. Regards,James Harrison

Does Kerberos issue a service ticket as part of the user-find command, or does it not get that far? (klist, and server logs will tell this.)
