Nextcloud/SSO with FreeIPA
by Daniel Pätzold 06 Dec '24

06 Dec '24

Hello, i have setup Freeipa (on Docker) and was able to logon via pam / SSSD on some host. Klist shows a valid Ticket and in Firefox i am able to log into FreeIPAs WebUI using SSO/Kerberos as the User i am logged in. I would like to have Nextcloud (also on Docker) use SSO Kerberos. There are many Apps in Nextcloud and i don't know howto start: SSO/SAML, Social Logon, Backend LDAP, OpenID, OAuth... I only found one Documentation an SSO in Nextcloud but its behind a paywall (and our Company is too small to get a subscription). Does anybody got this working? Which Nextcloud Apps should be used and how would they be configured? -- -- Mit freundlichen Grüßen Daniel Pätzold

Two-way trusts and AD Linux client.
by Aleksandr Sabirov 04 Dec '24

04 Dec '24

Hello, Suppose we have: Machine - with the full name ws16.ad16.loc - MS AD. Windows Server 2016 Machine - with the full name ipasrv-1.ipadomain.loc - IdM AD version 4.8.10. Linux Debian Machine - with the full name adclient-1.ad16.loc - AD Client. Linux Debian Bidirectional trust relationships between IPA and AD are configured. The third machine is joined to the AD domain using sssd 2.4.0. Can I somehow authenticate on the AD client (third machine) using IdM users via the bidirectional trust relationships? That is, I don't mean the case where we make the AD client partially integrated into IdM by adding settings in sssd.conf for the second domain ([domain/ipadomain.loc]) and updating krb5.keytab. I mean, how can I make it so that the request goes specifically through AD (i.e., via the trust relationships) and not directly to IdM? And is this possible? Thanks.

Crashes in bind9 name.c:667: REQUIRE((name1->attributes & 0x00000001) == (name2->attributes & 0x00000001))
by Kees Bakker 02 Dec '24

Hi, After a scheduled power down on and power up on one of our IPA servers named crashed. I remember I saw this before and that it was "solved" by restarting named. This time however it took about 12 retries before named finally continued. This is the error it produces ../../../lib/dns/name.c:667: REQUIRE((name1->attributes & 0x00000001) == (name2->attributes & 0x00000001)) failed, back trace bind9 is quite drastic when it hits a failing REQUIRE. It immediately stops with a coredump. But it doesn't tell which names are failing the comparison. Of course I can (or should) report this to the bind developers. However, I'm sure they are going to say that this is an old version and that I should ask CentOS/RH devs. If anybody here on the list has an idea, then please let me know. Some more details Version info: * os: CentOS 9-Stream * ipa packages 4.12.0-4.el9 * bind9 packages 32:9.16.23-15.el9 * bind-libdyndb-ldap 11.9.8-el9 Stack trace: Stack trace of thread 6432: #0 0x00007fb5a348b94c __pthread_kill_implementation (libc.so.6 + 0x8b94c) #1 0x00007fb5a343e646 raise (libc.so.6 + 0x3e646) #2 0x00007fb5a34287f3 abort (libc.so.6 + 0x287f3) #3 0x00005570cbbea5b5 assertion_failed.cold (named + 0x1c5b5) #4 0x00007fb5a433d420 isc_assertion_failed (libisc-9.16.23-RH.so + 0x1c420) #5 0x00007fb5a409f9ca dns_name_equal (libdns-9.16.23-RH.so + 0x9f9ca) #6 0x00007fb5a40b48ec dns_order_find (libdns-9.16.23-RH.so + 0xb48ec) #7 0x00007fb5a4429de8 query_addrrset.lto_priv.0 (libns-9.16.23-RH.so + 0x1dde8) #8 0x00007fb5a442eece query_gotanswer (libns-9.16.23-RH.so + 0x22ece) #9 0x00007fb5a4432b8b fetch_callback (libns-9.16.23-RH.so + 0x26b8b) #10 0x00007fb5a43781bd isc_task_run (libisc-9.16.23-RH.so + 0x571bd) #11 0x00007fb5a43632a9 process_netievent (libisc-9.16.23-RH.so + 0x422a9) #12 0x00007fb5a4363425 process_queue (libisc-9.16.23-RH.so + 0x42425) #13 0x00007fb5a4363c17 async_cb (libisc-9.16.23-RH.so + 0x42c17) #14 0x00007fb5a4285afd uv__async_io.part.0 (libuv.so.1 + 0xaafd) #15 0x00007fb5a42a185e uv__io_poll.part.0 (libuv.so.1 + 0x2685e) #16 0x00007fb5a428b568 uv_run (libuv.so.1 + 0x10568) #17 0x00007fb5a43634db nm_thread (libisc-9.16.23-RH.so + 0x424db) #18 0x00007fb5a4375f9a isc__trampoline_run (libisc-9.16.23-RH.so + 0x54f9a) #19 0x00007fb5a3489c02 start_thread (libc.so.6 + 0x89c02) #20 0x00007fb5a350ec40 __clone3 (libc.so.6 + 0x10ec40) -- Kees

If I try to set the userPassword attribute to some value with an LDAP browser and chose "plaintext" the value gets hashed immediately. I do see {PBKDF2_SHA256}. As a consequence the user cannot be activated. What am I doing wrong? I tried to enable migration mode and wanted to try it again but now I cannot connect to IPA's LDAP directory at all anymore...

Problem updating IPA
by Sava Savchev 22 Nov '24

22 Nov '24

I am running two IPA servers in replication on Oraclelinux8 with version ipa-server-4.9.13-10.0.1 and 389-ds version 1.4.3.39-8 When I try to update IPA to ipa-server-4.9.13-12.0.2 it fails on ipa-server-upgrade due to dirsrv not starting: ipa-server-upgrade Upgrading IPA:. Estimated time: 1 minute 30 seconds [1/9]: saving configuration [2/9]: disabling listeners [3/9]: enabling DS global lock [4/9]: disabling Schema Compat [5/9]: starting directory server [error] CalledProcessError: CalledProcessError(Command ['/bin/systemctl', 'start', 'dirsrv@.service'] returned non-zero exit status 1: 'Job for dirsrv@.service failed because the control process exited with error code.\nSee "systemctl status dirsrv@.service" and "journalctl -xe" for details.\n') [cleanup]: stopping directory server [cleanup]: restoring configuration IPA server upgrade failed: Inspect /var/log/ipaupgrade.log and run command ipa-server-upgrade manually. Unexpected error - see /var/log/ipaupgrade.log for details: CalledProcessError: CalledProcessError(Command ['/bin/systemctl', 'start', 'dirsrv@.service'] returned non-zero exit status 1: 'Job for dirsrv@.service failed because the control process exited with error code.\nSee "systemctl status dirsrv@.service" and "journalctl -xe" for details.\n') The ipa-server-upgrade command failed. See /var/log/ipaupgrade.log for more information In dirsrv logs there is: ERR - NSMMReplicationPlugin - changelog program - changelog5_init: failed to start changelog at /var/lib/dirsrv/slapd/cldb When I revert back to the original version, everything is back to normal. I have another cluster with the same configuration and I successfully updated. The only difference is that on the failing one I have enabled changelog encryption. I don't know if this is the correct list to report this problem, but since it is emerging when I update IPA, I guess this is the right one :)

Free User Certificates - EC certificstes
by Winfried de Heiden 21 Nov '24

21 Nov '24

Hi all, Previously, in another post, I mentioned slowness using Aventra MyEID PKI cards for login, sudo etc. I tried another solution, using EC (Elastic Curve) keys. Speed should benefit, since EC keys are much smaller, keeping the same degree of security. Shoter key = loading faster. Hoever, I seems FreeIPA will not accept and EC key, omly RSA when trying to sing an EC CSR? Would it be possible though to use Elastic Curve certificates? Thanks! Winfried

SRV and URI records are not cleaned after ipa server-del
by Kees Bakker 18 Nov '24

18 Nov '24

Hi, After I did a "ipa server-del" I was expecting that the SRV and URI records were cleaned up as well. But they weren't. I'm talking about DNS records like _kerberos.example.com _kerberos_tcp.example.com _ldap_tcp.example.com etc Is this a known issue? Am I expected to cleanup these entries myself? after a ipa server-del -- Kees

Disabling "kinit admin" on all machines
by Dominik Vogt 18 Nov '24

18 Nov '24

What is the correct way to disable "kinit admin" on all ipa clients? In our setup, becoming admin should only possible on the ipa server. (Everything is done by scripts runn through ssh; nobody ever logs in to the server directly.) Ciao Dominik ^_^ ^_^ -- Dominik Vogt
