geo replication - ? - concept of
by lejeczek 31 Mar '22

31 Mar '22

Hi guys. This must have been asked/covered somewhere I think, as it must be trivial concept/question many must have wondered - can IPA, in supported manner with built-in way or not, do 'geo-repliacation' in some sense? What I wonder specifically is - call it a secondary, backup or a mirror site(of whole domain) which would _only_ receive(possibly synchronously) and be read-only but!... that direction, the flow of main/primary -> secondary/backup could be flipped, reversed(in relatively non-time consuming way) Anybody done or contemplated such or similar thing and care to share some thoughts? many thanks, L.

ipa-ca DNS record - ?
by lejeczek 31 Mar '22

31 Mar '22

Hi guys. What is 'ipa-ca' for and what should it point to? Also, should IPA change that record ever? Reason I ask - from the docs as I understand - it should point to all CA servers in the domain, but it not happening. many thanks, L.

upgrade to FreeIPA 4.7+ from 4.6
by Ivars Strazdins 31 Mar '22

31 Mar '22

Hello, I am planning FreeIPA servers’ upgrade from Centos 7 with FreeIPA 4.6.8 to Alma Linux 8.5. Can I just take out replicas one by one and install fresh Alma Linux, then add back with latest FreeIPA on that replica? Or do I have to take some special precautions? If FreeIPA version compatibility is not a concern, perhaps it is even possible to do in-place upgrade with ELevate <https://wiki.almalinux.org/elevate/> (Leapp utility) ? Thank you in advance, Ivars Strazdins

Unable to create AD trust

Hello I am running CentOS 7.9 FreeIPA 4.6.8 Installed with integrated DNS and CA A replica will be installed after the trust is established with the AD domain. When trying to create a trust with AD i get the following error message (it seems to be somewhat random but goes back and forth between these two) Fetching domains from trusted forest failed OR ipa: ERROR: cannot connect to 'https://<server>/ipa/session/json': Gateway Timeout I have done the following to troubleshoot: - disable Selinux, which makes no difference - check firewall ports. for your reference I have the following defined services: freeipa-ldap, freeiipa-ldaps, http, https, kerberos, ntp, dns, ssh ports: 749/tcp, 7389/tcp, 8005/tcp, 8009/tcp - check DNS, it all verifies properly according to 5.2.1.2 https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/ht… - enabled debugging per https://www.freeipa.org/page/Active_Directory_trust_setup#Establish_and_ver… - disabled DNSSEC per https://access.redhat.com/solutions/2263991 I do see something of interest in the error_log but I am not sure if this is the problem. wsgi:error Timeout when reading response headers from daemon process 'ipa': /usr/share/ipa/wsgi.py ipa: ERROR: Failed to call com.redhat.idm.trust.fetch_domains helper.

How to retrieve user's credentials from IPA database?
by Roger Seguin 30 Mar '22

30 Mar '22

We have a GUI-based computer program that drives an external device/machine. By default our software only displays limited information on that external device. However, when a power user (group defined in /etc) identifies himself by entering their credentials through our software GUI, our software then checks those credentials against /etc/shadow using crypt() and getspnam() and, if succesful, provides extra functions for configuring our external device/machine. Actually, our software runs on several networked computers and our users, which are all local (defined in /etc), are duplicated on each computer. This is not ideal and we would rather like to have all users managed by IPA in a central place (dedicated computer as the IPA server) with our software running in IPA clients. Therefore, our software won't be able to check users' credentials using the local /etc/shadow file anymore. Basically, we would need to be able to query IPA programmatically (C language - or at least a shell script) to check that a username+password is correct. How can we process? Thanks

possible to auth FreeIPA users against another LDAP server?
by Jarett DeAngelis 29 Mar '22

29 Mar '22

hi everyone, I am trying (with great difficulty!) to do authn/authz both for an HPC cluster and a number of other Linux machines against our Okta directory service. Okta offers their "Advanced Server Access" product, which is *bonkers* expensive for the ~6 or 7 machines we need to auth with at $10K a year, and Aquera has a plugin for FreeIPA they maintain which will auth FreeIPA against Okta for another $10K a year. this is a small HPC lab and we're just trying to avoid as much credential proliferation as we can. my hope is that FreeIPA can be configured to auth against Okta's "built in" LDAP service, which is fairly minimal but will validate passwords and return some basic information in response to queries like group membership. then I can join machines to FreeIPA, which will in turn auth against Okta to allow users to log in. is this possible? thanks!

Hi Florence, I really appreciate your help so far, however I'm till not getting anywhere trying to fix this issue.
