Hi there, clients are having trouble with kerberos authentication:
$ kinit -V user
Using existing cache: xxxxxxxxxx:yyyyy
Using principal: user(a)SUB.EXAMPLE.COM <roberto(a)SUB.EXAMPLE.COM>
Password for user(a)SUB.EXAMPLE.COM <roberto(a)SUB.EXAMPLE.COM>:
kinit: Generic error (see e-text) while getting initial credentials
On the ipa server, /var/log/krb5kdc.log says:

There are 2 ipa servers, ipa01 (Rocky 9.3, ipa 4.10.2) and ipa02 (Rock 9.1,
ipa4.10.0), both with CA and DNS. ipa02 is CRL master.
On both, ipa-healthcheck doesn't find any issue.
Also: kinit fails from within ipa01, succeeds from within ipa02.
The issue seems to be in ipa01, and I have already tried to reinstall it
from scratch. One thing that is different is the version.
Could you please help me figure out what's wrong?
Best regards,
Roberto
