I'm currently running 3 Fedora 37 VMs (freeipa01, freeipa02 and freeipa03), running FreeIPA in a cluster. I decided today to upgrade the freeipa03 VM to Fedora 38. After the upgrade, I am no longer able to successfully login to the FreeIPA web GUI on this VM using my account credentials, nor am I able to 'kinit' successfully on the VM either with this account. Using the same account on the other two Fedora 37 VMs still works, so I would like to resolve this issue before upgrading the rest of the cluster. Note that the 'admin' account still works on freeipa03, though, both in the GUI and using 'kinit'. It also seems that pure LDAP authentication is unaffected (i.e. I can log in successfully with my account using the OpenLDAP client).

Suspecting that the problem might be Kerberos-specific, I followed the instructions on this page ( https://www.freeipa.org/page/Troubleshooting/Kerberos ) and ran (user and domain names changed to protect the innocent):

Something I see different between the working Kerberos authentication on freeipa01 and freeipa02 and the non-working one on freeipa03 is the presence of this line in '/var/log/krb5kdc.log' on freeipa03:

-------------- Sep 19 18:09:07 freeipa03.infra.example.com krb5kdc[888](info): AS_REQ (6 etypes {aes256-cts-hmac-sha1-96(18), aes256-cts-hmac-sha384-192(20), camellia256-cts-cmac(26), aes128-cts-hmac-sha256-128(19), aes128-cts-hmac-sha1-96(17), camellia128-cts-cmac(25)}) 192.168.40.133: HANDLE_AUTHDATA: [email protected] for krbtgt/[email protected], No such file or directory --------------

On Fedora 38, I am running FreeIPA 4.10.2, whereas on Fedora 37 I am running 4.10.1.

I found this RedHat article ( https://access.redhat.com/solutions/7015184 "Cannot authenticate using Kerberos after upgrading Red Hat Identity Management") which describes the problem as: "After updating ipa-server to 4.10.1-3 or newer, domain users cannot login anymore with Kerberos" with the exact same 'kinit <user>' error I obtained, and the same error line in '/var/log/krb5kdc.log'.

The article then suggests running the following:

-------------- $ kinit admin $ ipa config-mod --enable-sid --add-sids

Check if a SID has been generated for the user:

$ ipa user-show <user> --all | grep ipantsecurityidentifier ipantsecurityidentifier: S-1-5-21-198193297-2287641477-1368658080-1001 --------------

So, I ran 'ipa config-mod --enable-sid --add-sids', but even after running this command 'ipa user-show buddy --all | grep ipantsecurityidentifier' still shows up empty.

Since this seems to be the exact same problem I have, but it doesn't seem to fix my particular situation, is there anything else I need to do and/or check?

Thank you, -Martin
