Do keytabs expire?
by Ronald Wimmer 07 Jun '23

07 Jun '23

Hi, today I found out that some entries in a keytab file seemed to have expired: Request ticket server HTTP/mwc.linux.mydomain.at(a)LINUX.MYDOMAIN.AT kvno 4 not found in keytab; keytab is likely out of date Fetching the keytab again with ipa-getkeytab fixed the problem. But why is this happening? Do keytab entries expire? I have not set any custom password or ticket policies. Regards, Ronald

IPA CA allow CSR SAN names in external domains
by Steve Dainard 15 Mar '22

15 Mar '22

Hello I have a RHEL7 IPA server installed as a subordinate CA. I'd like to be able to add SAN's for a different dns domain than exists in the IPA realm. The dns for 'otherdomain.com' is handled by active directory which my IPA server has a cross-forest trust with. ie: host: client1.ipadomain.com certificate: CN = client1.ipadomain.com, SAN = client1.ipadomain.com, servicename.otherdomain.com When I try to submit this CSR with 'ipa-getcert request' the IPA server denies with: "The service principal for subject alt name servicename.otherdomain.com in certificate request does not exist" It seems that the default CAACL enforces a profile named 'caIPAserviceCert', but I'm having some trouble determining what can be modified (or cloned and changed in a new profile) that would allow the CA to sign a CSR that contains *.ipadomain.com and *.otherdomain.com in the SAN. This is the only section in the profile that contains SAN: policyset.serverCertSet.12.constraint.class_id=noConstraintImpl policyset.serverCertSet.12.constraint.name=No Constraint policyset.serverCertSet.12.default.class_id=commonNameToSANDefaultImpl policyset.serverCertSet.12.default.name=Copy Common Name to Subject Alternative Name Thanks, Steve

freeipa with sudo and 2FA (OTP)
by John Ratliff 31 Jan '22

31 Jan '22

I'm trying to setup freeipa with OTP. I created a TOTP under my user in freeipa and updated my user to use 2FA (password + OTP). When I try to do sudo, it only asks for my password and it fails every time (presumably because it isn't getting the OTP first). I didn't see anything useful in the sss_sudo logs, even after adding debug_level = 6 in the config. What can I do to further troubleshoot this? Thanks.

kinit -n asking for password on clients
by John Ratliff 13 Jul '20

13 Jul '20

When trying to do pkinit, if I do kinit -n on one of the IdM servers, it works fine. If I try on a client machine, it asks me for the password for WELLKNOWN/ANONYMOUS@REALM. I have the pkinit_anchors setup for the realm. As I'm trying to do anonymous pkinit, I think I don't need a client certificate. On the server, I get this: $ KRB5_TRACE="/dev/stderr" kinit -n [13061] 1518402857.924212: Getting initial credentials for WELLKNOWN/ANONYMOUS(a)IDM.EXAMPLE.COM [13061] 1518402857.929673: Sending request (200 bytes) to IDM.EXAMPLE.COM [13061] 1518402857.931830: Initiating TCP connection to stream 10.77.9.101:88 [13061] 1518402857.932241: Sending TCP request to stream 10.77.9.101:88 [13061] 1518402857.939162: Received answer (359 bytes) from stream 10.77.9.101:88 [13061] 1518402857.939180: Terminating TCP connection to stream 10.77.9.101:88 [13061] 1518402857.939284: Response was from master KDC [13061] 1518402857.939380: Received error from KDC: -1765328359/Additional pre-authentication required [13061] 1518402857.939474: Processing preauth types: 16, 15, 14, 136, 19, 147, 2, 133 [13061] 1518402857.939499: Selected etype info: etype aes256-cts, salt "IDM.EXAMPLE.COMWELLKNOWNANONYMOUS", params "" [13061] 1518402857.939509: Received cookie: MIT [13061] 1518402857.939563: Preauth module pkinit (147) (info) returned: 0/Success [13061] 1518402857.940352: PKINIT client computed kdc-req-body checksum 9/D98A0144E7E4ACC66B63EBCA98379AB9F055D143 [13061] 1518402857.940369: PKINIT client making DH request [13061] 1518402858.935: Preauth module pkinit (16) (real) returned: 0/Success [13061] 1518402858.956: Produced preauth for next request: 133, 16 [13061] 1518402858.994: Sending request (1408 bytes) to IDM.EXAMPLE.COM [13061] 1518402858.1091: Initiating TCP connection to stream 10.77.9.101:88 [13061] 1518402858.1187: Sending TCP request to stream 10.77.9.101:88 [13061] 1518402858.43063: Received answer (2880 bytes) from stream 10.77.9.101:88 [13061] 1518402858.43088: Terminating TCP connection to stream 10.77.9.101:88 [13061] 1518402858.43198: Response was from master KDC [13061] 1518402858.43258: Processing preauth types: 17, 19, 147 [13061] 1518402858.43273: Selected etype info: etype aes256-cts, salt "IDM.EXAMPLE.COMWELLKNOWNANONYMOUS", params "" [13061] 1518402858.43300: Preauth module pkinit (147) (info) returned: 0/Success [13061] 1518402858.44150: PKINIT client verified DH reply [13061] 1518402858.44189: PKINIT client found id-pkinit-san in KDC cert: krbtgt/IDM.EXAMPLE.COM(a)IDM.EXAMPLE.COM [13061] 1518402858.44199: PKINIT client matched KDC principal krbtgt/IDM.EXAMPLE.COM(a)IDM.EXAMPLE.COM against id-pkinit-san; no EKU check required [13061] 1518402858.62345: PKINIT client used KDF 2B06010502030602 to compute reply key aes256-cts/00E0 [13061] 1518402858.62395: Preauth module pkinit (17) (real) returned: 0/Success [13061] 1518402858.62402: Produced preauth for next request: (empty) [13061] 1518402858.62414: AS key determined by preauth: aes256-cts/00E0 [13061] 1518402858.62547: Decrypted AS reply; session key is: aes256-cts/96F0 [13061] 1518402858.62589: FAST negotiation: available [13061] 1518402858.62692: Initializing KEYRING:persistent:760400007:krb_ccache_f3PFEy1 with default princ WELLKNOWN/ANONYMOUS@WELLKNOWN:ANONYMOUS [13061] 1518402858.62770: Storing WELLKNOWN/ANONYMOUS@WELLKNOWN:ANONYMOUS -> krbtgt/IDM.EXAMPLE.COM(a)IDM.EXAMPLE.COM in KEYRING:persistent:760400007:krb_ccache_f3PFEy1 [13061] 1518402858.62846: Storing config in KEYRING:persistent:760400007:krb_ccache_f3PFEy1 for krbtgt/IDM.EXAMPLE.COM(a)IDM.EXAMPLE.COM: fast_avail: yes [13061] 1518402858.62878: Storing WELLKNOWN/ANONYMOUS@WELLKNOWN:ANONYMOUS -> krb5_ccache_conf_data/fast_avail/krbtgt\/IDM.EXAMPLE.COM\@IDM.EXAMPLE.COM@X-CACHECONF: in KEYRING:persistent:760400007:krb_ccache_f3PFEy1 [13061] 1518402858.62933: Storing config in KEYRING:persistent:760400007:krb_ccache_f3PFEy1 for krbtgt/IDM.EXAMPLE.COM(a)IDM.EXAMPLE.COM: pa_type: 16 [13061] 1518402858.62954: Storing WELLKNOWN/ANONYMOUS@WELLKNOWN:ANONYMOUS -> krb5_ccache_conf_data/pa_type/krbtgt\/IDM.EXAMPLE.COM\@IDM.EXAMPLE.COM@X-CACHECONF: in KEYRING:persistent:760400007:krb_ccache_f3PFEy1 But on the client, I get this: $ KRB5_TRACE="/dev/stderr" kinit -n [2941] 1518402820.155827: Getting initial credentials for WELLKNOWN/ANONYMOUS(a)IDM.EXAMPLE.COM [2941] 1518402820.156298: Sending request (200 bytes) to IDM.EXAMPLE.COM [2941] 1518402820.158723: Resolving hostname paine.example.com.

FreeIPA v4.5.0 install lost topology suffixes
by Gavin Williams 19 Aug '19

19 Aug '19

Afternoon all I’ve got a slightly strange one with one of our FreeIPA clusters, whereby the topology suffixes appear to have disappeared. From what I can see, this is causing replication issues between the hosts, which is causing us issues with bootstrapping new clients against FreeIPA. I’m not aware of any config changes that have happened on the FreeIPA hosts that could have caused this issue, so am a bit stumped atm. Is someone able to advise next steps on how to investigate the cause and correct the configuration? Regards Gavin

DNS A Record Disappears after IPA Server reboot
by Mariusz Stolarczyk 27 Jul '19

27 Jul '19

Hi all, Whenever I have to reboot my IPA server I loose one of my IPA client's DNS A Record. Curiously all of the IPA client related SSHFP records are intact as well as the reverse lookup record. The only thing that was slightly different about this client is at some point the IP address was changed. I did however change the IP address on a different client with no problems. Thanks, -Mark

IPA users and local groups question
by Jeff Goddard 11 Jun '19

11 Jun '19

First off thanks to everyone who makes FreeIPA. Its an awesome product that we love. We're working at breaking our application up into micro services and using docker containers and deployment automation. As part of this I have a deploy user in IPA and a rundeck server that performs tasks as this user. However, we need this user to be part of the local docker hosts "docker" group. Is this something I have to do manually per host? Is it possible to create a docker IPA group that will substitute for the local docker group and do it all in IPA? Our IPA version is 4.4. The servers are Centos 7.2 and the clients are ubuntu 16.04 LTS. Thanks for the insight, references and help, Jeff

Hi guys, Anyone got this working? And if so, how did you do it? I know I can monitor the components separately, but if you know of anything that can do it easier I'd be happy to know about it. /tony -- -- Tony Albers Systems administrator, IT-development Royal Danish Library, Victor Albecks Vej 1, 8000 Aarhus C, Denmark.

ipa-getkeytab: PrincipalName not found
by Harald Dunkel 26 Apr '19

26 Apr '19

Hi folks, maybe I missed something, but shouldn't admin have sufficient privileges to run # ipa-client-install --hostname stretch1.vs.example.de --no-ssh --no-sshd --no-nisdomain --no-sudo --no-ntp --no-dns-sshfp # reboot : : # kinit admin # ipa-getkeytab -s ipa1.example.de -p HTTP/stretch1.vs.example.de -k /etc/apache2/apache2.keytab ? ipa-getkeytab failed with Failed to parse result: PrincipalName not found. I would have expected it to create the principal on the fly. "admin" was created at freeipa install time on the first server, AFAIR. It is member of the "admins" and "trust admins" groups. I am concerned that I corrupted something. Every helpful comment is highly appreciated. Harri
