Certificate renewals with external CA
by Rob Foehl 29 Aug '17

29 Aug '17

I've got a test instance of FreeIPA 4.4.4 running on F25 that was installed with --external-ca, and the resulting CSR signed with a validity period of 30 days to test behavior around expirations. Upon booting that instance today, certmonger decided to preemptively renew every IPA cert -- which is a good thing -- but did so without waiting for renewal of the IPA CA cert first, which is less good. Now that instance has a pile of certs that expire in two weeks, since they were signed with and thus tied to the expiration of the old IPA CA cert. While I'm guessing certmonger will figure this out and do the right thing within a couple weeks -- and with the expectation that this would only happen once per IPA CA renewal with a "real" deployment -- is this the intended behavior? Logs are a bit of a mess between this and a potentially-resolved SELinux issue with certmonger, but I'll wedge them all into a proper bug report if desired. -Rob

Time Skew on Amazon nodes?
by pgb205 01 Aug '17

01 Aug '17

I have noticed that we had a broken replication agreement between replica in amazon and on another physical node. I have attempted to re-initialize but receivedUpdate failed! Status: [2 Replication error acquiring replica: excessive clock skew] I had triple verified that time on both is correct and at most within seconds of each other. in dirsrv logs I get Excessive clock skew from supplier RUVUnable to acquire replica: error: excessive clock skew After doing a bit of searching I found this beauty:https://www.redhat.com/archives/freeipa-users/2014-February/msg00007… The article mentions that the time skew might occur due to server being virtualied, and I'm wondering if this is applicable to Amazon. The steps mentioned in the article look intrusive (and intimidating) . I'm curious what other avenues are available to me to fix this?If I blow away the replica and re-set up the new one from scratch would that fix the problem.

Re: FreeIPA - Active Directory integration and domain names
by Striker Leggette 06 Jul '17

Well, technically, I don't think IPA needs DNS entries simply for synchronization, so you could technically give it the same domain suffix. However, if you plan on using it for the purpose of clients to connect, it will need to be on its own domain. The reason it is highly suggested for different domains to have different suffixes within DNS is because clients will 'dig' that domain for Kerberos and LDAP type records when looking for domain servers. Something like the below, for example: # dig -t SRV _kerberos._tcp.EXAMPLE.COM. If this returns both AD /and/ IPA servers, your clients will have a bad time.

In the documentation it is stated that to use a cross-forest trust it is required for FreeIPA to have a different domain than that of Active Directory. Does it also apply to the synchronization scenario?

Syncronization on servers
by Ataliba Teixeira 05 Jul '17

05 Jul '17

Hello, reading some docs about the sync of my two servers : # ipa-replica-manage list server1.domain: master server2.domain: master # ipa-replica-manage list-ruv Directory Manager password: Replica Update Vectors: server2.domain:389: 7 server1.domain:389: 4 Certificate Server Replica Update Vectors: No CS-RUVs found. My doubt is . To solve this i only need to run the command : ipa-replica-manage force-sync --from srv2.domain ? Thanks for your atention :-) -- Ataliba Teixeira via Inbox by Gmail

Errors after Upgrading from Fedora 23 to Fedora 25
by dntosas＠yuboto.com 03 Jul '17

Hello World! I got an installation with FreeIPA server 4.2.4 in Fedora 23 and all worked fine I decided to upgrade to Fedora 25 via dnf-upgrade-plugin All the upgrade proc goes smooth and as a result my freeipa rpm packages also upgraded (from 4.2.4 to 4.4.4) Now, the problem is that nothing works now. The command "ipa-server-upgrade" shows: IPA server upgrade failed: Inspect /var/log/ipaupgrade.log and run command ipa-server-upgrade manually. Timeout exceeded The ipa-server-upgrade command failed.

FreeIPA 4.5.2 with AD Trust - Web UI trouble
by Jason Hensley 29 Jun '17

29 Jun '17

Hello, I have setup a pair of FreeIPA 4.5.2 servers. One via ipa-server-install, the other via ipa-replica-install. I have tried them both as trust controllers and I have tried them in a controller/agent setup. My problem is that no AD users can login to the self service UI on the secondary IPA server. Is this by design, or is it merely a bug? I can provide more details/logs/configs on request. Thanks, Jason

New to FreeIPA cant figure out integrated DNS.
by euanhaahrmail2＠gmail.com 29 Jun '17

29 Jun '17

I have been trying to install FreeIPA with integrated dns i found installing freeipa easy without dns but anything todo with the dns portion of it exceeding complicated. I have a internel dns server that i have been using to store all the host names of my internel pcs and then for anything externel it would forward to another dns server. As far as i can tell the freeipa integrated dns is would replace this and would store all the records needed for freeipa also as far as i can tell it would automatically create the A records and AAAA records for the client pcs added to the domain and keep them updated. I originally tried making the integrated dns handle the root zone i think that is what its called where it could create records for any subdomains I read online that this wasnt a good idea and also seemed extremely hard todo trying this would end up in a zone overlap error. I think I need to make my registrar point to the integrated dns for this to work. I read some guides and it seems that people suggest to give the integrated dns server power over its own subdomain zone I did this by creating a NS record in my registrars dns management page but when running the command suggested in the redhat guide to check that it works it returns nothing this is the command i am running "dig @RegistrarsNameServerIPAddress +norecurse +short ipa.example.com. NS" but running a normal dig will show the record. ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 4096 ;; QUESTION SECTION: ;ipa.example.com. IN A ;; AUTHORITY SECTION: ipa.example.com. 1799 IN NS ipa.example.com. ;; ADDITIONAL SECTION: ipa.example.com. 1799 IN A MyIPAddress When trying to install using this subdomain I get this error right at the end. I have a feeling it is trying to add records to the integrated dns server but its not working properly. “Updating DNS system records ipa : ERROR DNS query for ipa.example.com. 1 failed: All nameservers failed to answer the query ipa.example.com. IN A: Server 127.0.0.1 UDP port 53 anwered SERVFAIL” I think my main problem with this is I actually dont know how DNS delegates subdomain nameservers it always asks for a FQDN when putting in a nameserver but shouldnt this really be an ip address. If someone could give me and example NS record or how they have set it up that would be great I am extremely lost even some reading materials would be helpful all guides online just assume you already have setup the NS record and don’t give you too much information. Also I have replace all refrences to my domain to example.com (not actually trying to use example.com).

Error running ipa-certupdate
by Jeff Fouchard 29 Jun '17

29 Jun '17

On our clients when attempting to run ipa-certupdate we are seeing the following error: ipa.ipapython.ipaldap.SchemaCache: DEBUG: retrieving schema for SchemaCache url=ldap://ldap2.int.ba.mydomain.local:389 conn=<ldap.ldapobject.SimpleLDAPObject instance at 0x46dc5a8> ipa.ipaclient.ipa_certupdate.CertUpdate: DEBUG: File "/usr/lib/python2.7/site-packages/ipapython/admintool.py", line 171, in execute return_value = self.run() File "/usr/lib/python2.7/site-packages/ipaclient/ipa_certupdate.py", line 87, in run lwcas = api.Command.ca_find()['result'] File "/usr/lib/python2.7/site-packages/ipalib/plugable.py", line 336, in __getattr__ raise AttributeError(key) ipa.ipaclient.ipa_certupdate.CertUpdate: DEBUG: The ipa-certupdate command failed, exception: AttributeError: ca_find ipa.ipaclient.ipa_certupdate.CertUpdate: ERROR: ca_find ipa.ipaclient.ipa_certupdate.CertUpdate: ERROR: The ipa-certupdate command failed. We have recently migrated to using an external CA and that went smoothly other than this. We had not tried prior to that to run this command. So far this is happening on all of the nodes we have tried. It does seem our server version (4.2.0) and client version (4.4.0) are out of sync. Would that be the cause, or is there something else I should be looking at. Thanks! Jeff

{ possibly offtopic } -- can sssd.conf alone be configured to copy the custom AD ID Ranges used by IPA server?
by Chris Dagdigian 29 Jun '17

29 Jun '17

Hi folks, I have a set of servers that CANNOT become enrolled IDM clients due to a vendor refusing to support this type of config. This server fleet is directly bound to an AD system via the standard non-IPA "realm join ..." type commands Since I can't bring these servers "into the fold" so to speak at the very least I would love to offset at least one potential future problem by seeing if I can help them configure sssd.conf on their local machines to use the same AD SID-to-UID algorithm (complete with custom ID Range values that we have enabled on the IPA master) so that they at least get the same UID and GID values for their AD users as the same user would get if they logged into the much larger fleet of IDM-managed servers. Hope I'm asking the question properly -- in a nutshell I'm wondering how to trick a standalone sssd.conf file so that it uses the same SID-to-UID algorithm that an IDM master would use. This would at least let me get consistent UID/GID values across my fleet of enrolled vs. non-enrolled IDM clients ! Tips or advice appreciated even if the response is "heck no; you can't do that .. " Regards, Chris
