Problem running IPA client on IPv6 only connection
by William Muriithi 26 Jul '22

26 Jul '22

Hello, I have an IPA clients that has both IPv4 and IPv6 addresses. One of the IPA client is in the office and hence can reach the IPA server on both IPv4 and IPv6. However, the client outside the LAN can only reach the IPA server over IPv6. I was able to enroll the external client fine over IPv6 and from the logs, all clean. However, when I attempted to ssh, its not able to retreave the user from IPA. The client in the office works fine. I can also make for example LDAP queries and they work over IPv6 fine. It looks like kerberos is somehow however using IPv4. I reached this conclusion after taking a tcpdump when attempting to ssh to the server and the kerberos traffic from the client to IPA is on IPv4. What would I need to do on the IPA client for it to prefer IPv6? I am aware I could remove IPv4 address from DNS, but that would break any communication from IPv4 only systems. Any assistance would be appreaciated.

ssh key issues
by Andrew Meyer 21 Jul '22

21 Jul '22

I recently cleaned up a few server in my home lab. Deleted servers that I no longer needed. However It seems I have a server with an IP address that used previously. FreeIPA is reporting that it is in /var/lib/sss/pubconf/known_hosts but I can't reverse engineer the hostname by doing sshkey -R 1.2.3.4. I have run into this issue previously but it has bee quite some time. When I go to delete the line from /var/lib/sss/pubconf/known_hosts it is gone. If someone could help me that would be great. I didn't see anything on my FreeIPA master that indicated I did anything there.

Could not login with AD user
by Ronald Wimmer 20 Jul '22

20 Jul '22

Today I was not able to log in with an AD user to an IPA client within a test setup. IPA users worked fine. DNS is managed externally. I figured out that the DNS-Record of that particular IPA client has not been created correctly. After having corrected the DNS entry and having dropped the SSSD cache on that client I could login with my AD user. Do you have an explanation for that or was it just a coincidence? Cheers, Ronald

keycloak - the other way around?
by lejeczek 30 Jun '22

30 Jun '22

Hi guys. I've only stumbled upon whole Keycloak thing thus go easy on me please. I wonder if Keycload can be a "provider" to freeIPA in some way? One such a scenario where I think Keycloak might be a golden egg - if it worked that is - is as a "middle-man" for user base between(or from to) AD and freeIPA when full & legit trust is not possible. Does that make sense? many thanks, L.

freeipa/certmonger for openvpn user certificates
by Patrick Spinler 27 Jun '22

27 Jun '22

Hi, I'm setting up an openvpn server and I'd like to use our already existing FreeIPA CA to issue user keys/certs for openvpn's use. Since our OpenVPN box is a freeipa client, I thought it'd be nice to use certmonger to issue and keep up to date these certs. Ergo, I've created a certificate profile: pat@apex-freeipa ~$ ipa certprofile-show --all OpenVPNUserCert dn: cn=OpenVPNUserCert,cn=certprofiles,cn=ca,dc=int,dc=apexmw,dc=com Profile ID: OpenVPNUserCert Profile description: OpenVPN User Certificates Store issued certificates: FALSE objectclass: ipacertprofile, top And also a CA acl. For experimentation (and working vs our test freeipa) I've left this as wide open as I can: [pat@apex-freeipa ~]$ ipa caacl-show --all OpenVPN_User_Certificate_ACL dn: ipaUniqueID=6dde33a6-7849-11e9-aa05-525400b52c7b,cn=caacls,cn=ca,dc=int,dc=apexmw,dc=com ACL name: OpenVPN_User_Certificate_ACL Enabled: TRUE CA category: all Profile category: all User category: all Host category: all Service category: all ipauniqueid: 6dde33a6-7849-11e9-aa05-525400b52c7b objectclass: ipaassociation, ipacaacl Then, on my openvpn server, I ask for a cert for use for one of my users (myself, in this case): root@apex-openvpn:~# ipa-getcert request -f /etc/openvpn/client/pat.crt -k /etc/openvpn/client/pat.key -r -N 'CN=pat,O=INT.APEXMW.COM' -K pat -g 4096 --profile OpenVPNUserCert New signing request "20190603014016" added. But, it fails due to an access err vs the 'userCertificate' attribute of my account: root@apex-openvpn:~# ipa-getcert list (...snippy snip excess...) Request ID '20190603014016': status: CA_REJECTED ca-error: Server at https://apex-freeipa.int.apexmw.com/ipa/xml denied our request, giving up: 2100 (RPC failed at server.

Do I need to go a more traditional route of creating a seperate keystore/certdb, issuing a CSR, and feeding that to FreeIPA to sign? Any advice appreciated, and thanks in advance, -- Pat

Broken ipa replica
by Giulio Casella 08 May '22

08 May '22

Hi everyone, I'm stuck with a broken replica. I had a setup with two ipa server in replica (ipa-server-4.6.4 on CentOS 7.6), let's say "idc01" and "idc02". Due to heavy load idc01 crashed many times, and was not working anymore. So I tried to redo the replica again. At first I tried to "ipa-replica-manage re-initialize", with no success. Now I'm trying to redo from scratch the replica setup: on idc02 I removed the segments (ipa topologysegment-del, for both ca and domain suffix), on idc01 I removed everything (ipa-server-install --uninstall), then I joined domain (ipa-client-install), and everything is working so far. When doing "ipa-replica-install" on idc01 I get: [...] [28/41]: setting up initial replication Starting replication, please wait until this has completed. Update in progress, 22 seconds elapsed [ldap://idc02.my.dom.ain:389] reports: Update failed! Status: [Error (-11) connection error: Unknown connection error (-11) - Total update aborted] And on idc02 (the working server), in /var/log/dirsrv/slapd-MY-DOM-AIN/errors I find lines stating: [20/Mar/2019:09:28:06.545187923 +0100] - INFO - NSMMReplicationPlugin - repl5_tot_run - Beginning total update of replica "agmt="cn=meToidc01.my.dom.ain" (idc01:389)".

DNS record with all IPA servers
by Boris Behrens 11 Apr '22

11 Apr '22

Hi, I am currently trying to cleanup our IPA installation and saw that all our clients only got a single server configured, which doesn't sound good. (we've currently got two IPA servers). Is there some sort of record that can be used? root@host1:/etc/ipa# cat /etc/ipa/default.conf #File modified by ipa-client-install [global] basedn = dc=domain,dc=ca realm = DOMAIN.CA domain = DOMAIN.CA server = ipa1.domain.ca xmlrpc_uri = https://ipa1.domain.ca/ipa/xml enable_ra = True Cheers Boris -- Die Selbsthilfegruppe "UTF-8-Probleme" trifft sich diesmal abweichend im groÃƒ¼en Saal.

certs: SAN without othername / NT Principal name

Hi FreeiPA users, I'm having great fun with a web app that hates the othername/ NT Principal name included with certificates generated with ipa-getcert. I've tried several variations but can't omit this part of the subject alternative name. Is there any way to do so? Thanks in advance, David

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.
