I am running into a strange issue with a few user accounts where logging into the web interface gives them the error message "Login failed due to an unknown reason”. It also prevents them from SSH’ing into IPA bound systems using passwords. Pubkeys work fine (as long as it is manually added to the local accounts) and any services I have bound to it (Gitlab, Mattermost, Owncloud, etc) seem to work fine. I ’think’ this is kerberos related since the only services that are using it is SSH and probably the IPA web interface. Here is the apache error log for it: [Thu Jan 13 09:15:38.688228 2022] [wsgi:error] [pid 579266:tid 139812542121728] [remote xx.xxx.xx.xxx:52162] ipa: INFO: 401 Unauthorized: Major (851968): Unspecified GSS failure. Minor code may provide more information, Minor (2598844948): TGT has been revoked I ’think’ the message "TGT has been revoked” is due to the 401 error, since the user is not showing as being authorized to login. However, this user is enabled and I have tried a number of things to try to fix it: 1. Disable/Re-enable account 2. Reset passwords 3. Kinit username (seems to get a ticket, but logins still do not work) 4. Run the account migration task (using the web gui) 5. Restart the IPA server and services 6. Re-initialize the IPA server from another master Also, I can confirm that the passwords are correct since a failed password error message shows up differently and other services are using it correctly. Going down the Kerberos path, here is the krb5kdc log file: Jan 13 09:15:38 ipa.example.com krb5kdc[579226](info): AS_REQ (7 etypes {aes256-cts-hmac-sha1-96(18), aes256-cts-hmac-sha384-192(20), camellia256-cts-cmac(26), aes128-cts-hmac-sha1-96(17), aes128-cts-hmac-sha256-128(19), camellia128-cts-cmac(25), DEPRECATED:arcfour-hmac(23)}) yy.yy.yy.yy: NEEDED_PREAUTH: WELLKNOWN/ANONYMOUS(a)EXAMPLE.COM for krbtgt/EXAMPLE.COM(a)EXAMPLE.COM, Additional pre-authentication required Jan 13 09:15:38 ipa.example.com krb5kdc[579226](info): closing down fd 12 Jan 13 09:15:38 ipa.example.com krb5kdc[579226](info): AS_REQ (7 etypes {aes256-cts-hmac-sha1-96(18), aes256-cts-hmac-sha384-192(20), camellia256-cts-cmac(26), aes128-cts-hmac-sha1-96(17), aes128-cts-hmac-sha256-128(19), camellia128-cts-cmac(25), DEPRECATED:arcfour-hmac(23)}) yy.yy.yy.yy: ISSUE: authtime 1642094138, etypes {rep=aes256-cts-hmac-sha1-96(18), tkt=aes256-cts-hmac-sha1-96(18), ses=aes256-cts-hmac-sha1-96(18)}, WELLKNOWN/ANONYMOUS(a)EXAMPLE.COM for krbtgt/EXAMPLE.COM(a)EXAMPLE.COM Jan 13 09:15:38 ipa.example.com krb5kdc[579226](info): closing down fd 12 Jan 13 09:15:38 ipa.example.com krb5kdc[579225](info): AS_REQ (7 etypes {aes256-cts-hmac-sha1-96(18), aes256-cts-hmac-sha384-192(20), camellia256-cts-cmac(26), aes128-cts-hmac-sha1-96(17), aes128-cts-hmac-sha256-128(19), camellia128-cts-cmac(25), DEPRECATED:arcfour-hmac(23)}) yy.yy.yy.yy: NEEDED_PREAUTH: testuser(a)EXAMPLE.COM for krbtgt/EXAMPLE.COM(a)EXAMPLE.COM, Additional pre-authentication required Jan 13 09:15:38 ipa.example.com krb5kdc[579225](info): closing down fd 12 Jan 13 09:15:38 ipa.example.com krb5kdc[579225](info): AS_REQ (7 etypes {aes256-cts-hmac-sha1-96(18), aes256-cts-hmac-sha384-192(20), camellia256-cts-cmac(26), aes128-cts-hmac-sha1-96(17), aes128-cts-hmac-sha256-128(19), camellia128-cts-cmac(25), DEPRECATED:arcfour-hmac(23)}) yy.yy.yy.yy: ISSUE: authtime 1642094138, etypes {rep=aes256-cts-hmac-sha1-96(18), tkt=aes256-cts-hmac-sha1-96(18), ses=aes256-cts-hmac-sha1-96(18)}, testuser(a)EXAMPLE.COM for krbtgt/EXAMPLE.COM(a)EXAMPLE.COM Jan 13 09:15:38 ipa.example.com krb5kdc[579225](info): closing down fd 12 Jan 13 09:15:38 ipa.example.com krb5kdc[579226](Error): PAC issue: PAC record claims domain SID different to local domain SID or any trusted domain SID: local [S-1-5-21-997841278-3584560916-1456654135], PAC [S-1-5-21-2108153867-2082035330-3701898995] Jan 13 09:15:38 ipa.example.com krb5kdc[579226](info): TGS_REQ : handle_authdata (-1765328364) Jan 13 09:15:38 ipa.example.com krb5kdc[579226](info): TGS_REQ (7 etypes {aes256-cts-hmac-sha1-96(18), aes256-cts-hmac-sha384-192(20), camellia256-cts-cmac(26), aes128-cts-hmac-sha1-96(17), aes128-cts-hmac-sha256-128(19), camellia128-cts-cmac(25), DEPRECATED:arcfour-hmac(23)}) yy.yy.yy.yy: HANDLE_AUTHDATA: authtime 1642094138, etypes {rep=UNSUPPORTED:(0)} testuser(a)EXAMPLE.COM for HTTP/ipa.example.com(a)EXAMPLE.COM, TGT has been revoked Jan 13 09:15:38 ipa.example.com krb5kdc[579226](info): closing down fd 12 Jan 13 09:15:38 ipa.example.com krb5kdc[579226](Error): PAC issue: PAC record claims domain SID different to local domain SID or any trusted domain SID: local [S-1-5-21-997841278-3584560916-1456654135], PAC [S-1-5-21-2108153867-2082035330-3701898995] Jan 13 09:15:38 ipa.example.com krb5kdc[579226](info): TGS_REQ : handle_authdata (-1765328364) Jan 13 09:15:38 ipa.example.com krb5kdc[579226](info): TGS_REQ (7 etypes {aes256-cts-hmac-sha1-96(18), aes256-cts-hmac-sha384-192(20), camellia256-cts-cmac(26), aes128-cts-hmac-sha1-96(17), aes128-cts-hmac-sha256-128(19), camellia128-cts-cmac(25), DEPRECATED:arcfour-hmac(23)}) yy.yy.yy.yy: HANDLE_AUTHDATA: authtime 1642094138, etypes {rep=UNSUPPORTED:(0)} testuser(a)EXAMPLE.COM for HTTP/ipa.example.com(a)EXAMPLE.COM, TGT has been revoked I only see two errors that might be related: "PAC record claims domain SID different to local domain SID or any trusted domain SID” "DEPRECATED:arcfour-hmac(23)” However, those might just be red herrings or something else that is unrelated. So far, there are only a small number of accounts that have this problem, but more seem to be popping up on a daily basis. The only fix I have found is the nuclear option, where I completely remove the account and then add it back in with the same UID/GID, group memberships and policies. After that it seems to work fine. However, I would rather not want to do this to all accounts since that would be a logistical nightmare. Are there any suggestions for either troubleshooting or fixing this problem with a lighter approach? Is it possible to reset or regenerate the users kerberos authentication?

certmonger error on ubuntu
by Robson Francisco de Souza 07 Feb '24

07 Feb '24

Hello! I've been running FreeIPA 4.3.1 on Ubuntu 16.04 for almost two years and most certificates should expire within three weeks. As this deadline approaches, I noticed certmonger has been unable to renew certificates due to the error below. After googling for two days, I found this issue has been observed by many people before, mostly after expiration of the certificates, as in https://tinyurl.com/vajmocw Still, I couldn't find a solution to this problem. If it is impossible to fix this issue while using FreeIPA 4.3.1, I would like to: 1) Find a way to renew all certificates even if certmonger can't be fixed. This would allow me to postpone the solution to after the next OS and/or FreeIPA upgrade 2) Find out what version of FreeIPA I should upgrade to while the operating system remains Ubuntu 16.04 Any help would be appreciated! Thanks!

Greenfield FreeIPA deployment - is it OK to put FreeIPA at the domain apex, or a "best practice" to put it in a subdomain?
by Braden McGrath 11 Jan '24

11 Jan '24

Hello FreeIPA-users. The Subject line is the core of my question here; I'll provide a bit more detail below. I work for what is (effectively) a startup, non-profit internet provider. I have an extensive Windows background, and "know enough to be dangerous" with Linux & BSD (have been tinkering with GNU/Linux on and off since Slackware 3.0 or 3.1). I'm very familiar with Windows Active Directory, but the org does not have any AD infrastructure right now (and being nonprofit, are trying to avoid spending money for MS, especially when all of the other VMs will be Linux or BSD anyway). Given the nonprofit nature, I discovered FreeIPA when looking for a free centralized directory system. The goal is to consolidate all credentials for *other* Linux VMs (customer-facing DNS, CRM web server, SNMP/network graphing servers, etc) as well as provide a back-end for RADIUS for management of network equipment (switches, routers, P2P wireless, etc). Simplifying DNS management and replication is also appealing, I'd rather administrate one system than two or three. In case it changes your opinion of the plan at all - all of the network equipment and VMs will be on *private* (10.x) IPv4 space and behind one or more firewalls, at least initially. We do want to add public IPv6, but do not have that yet. We only have a small allocation (/26) of public v4 from our upstream that will be NATed through a firewall and not directly on any devices. The traffic to FreeIPA is going to be internal-only, I do not plan on exposing FreeIPA's DNS "to the world" at all. Even customer-facing internal DNS will likely be through separate caching forwarders pointing back to FreeIPA. I have a completely unused, publicly registered domain (let's just call it "example.net" for this thread) available to dedicate to this system. We also own "example.org" and are using that for our public web presence, and I intend to keep that entirely standalone. Given that I have no current "interoperability" concerns, is there anything "wrong" with putting FreeIPA directly at the root of example.net? Or would it be more wise, from an interop, security, or manageability standpoint (i.e. a "best practice"), to root FreeIPA at something like auth.example.net or ipa.example.net and then have a separate set of nameservers handling the base domain? If I put FreeIPA's root (and Kerberos realm) in a subdomain, is it possible to *also* have it manage the parent domain's DNS entries? I've read through the Quick Start Guide and Deployment Recommendations (https://www.freeipa.org/page/Deployment_Recommendations) which is part of how I've come to the decisions I've made thus far. I couldn't really find guidance one way or the other on whether FreeIPA "should" be in a subdomain or not, hence this posting. I would appreciate any insight the community can provide!

Auto cleanup old enrolled hosts
by Russ Long 01 Dec '23

01 Dec '23

We're adding FreeIPA to an immutable, often rotated environment (AWS ECS Hosts). These hosts are spun up and down at least daily. Is there a way to check FreeIPA to see when a host has last communicated with the FreeIPA Cluster? I'd like to use this information to auto-delete hosts that have not reported in from the FreeIPA host list.

Allow sysaccount to view its own entry
by Adam Bishop 09 Nov '23

09 Nov '23

I have a piece of software that tries to look up its own uid to check that LDAP is correctly configured. This check fails because the sysaccount cannot view anything under cn=etc,cn=sysaccounts. Is there an existing permission/privilege that I can use to allow it to read the sysaccounts tree (or better, just its own entry)? Many Thanks, Adam Bishop

kinit: KDC can't fulfill requested option while renewing credentials - which approach?
by Pieter Baele 19 Sep '23

19 Sep '23

I tried various approached to get Renewable tickets : modifying the kdc modifying krb5.conf using kadmin.local on every replica to modify the principal; which is not working - as designed (?)- in IPA What should I do to get a ticket with the correct R flag from IPA ? I don't think this is SSSD related (the service needing the renewable ticket this way is Apache Storm) Thanks a lot!

Limiting access to GUI
by Entrepreneur AJ 10 Jul '23

10 Jul '23

Hey all, I have a wan facing install due to many of my team operating with mobile phone hotspots whilst visiting customers. An Issue I'm having is I want to restrict the GUI to only our admin team's IP address but editing the Apache Config with; # webUI is now completely static, and served out of that directory Alias /ipa/ui "/usr/share/ipa/ui" <Directory "/usr/share/ipa/ui"> SetHandler None AllowOverride None Satisfy Any Require all granted ExpiresActive On ExpiresDefault "access plus 1 year" <FilesMatch "(index.html|loader.js|login.html|reset_password.html)"> ExpiresDefault "access plus 0 seconds" </FilesMatch> Order allow,deny Allow from <ADMIN IP RANGE> </Directory> Is still allowing anyone with a browser to reach the IPA gui. We have Keycloak in place for staff and users to update their passwords. Any pointers? I would personally prefer to firewall it off but that effects other IPA features.

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
