Hello,
I still not sure of what is happening but, I got some interesting error message on
ipa-healthcheck:
[root@neumann2 keytabs]# ipa-healthcheck --failures-only --output-type human
CRITICAL: ipahealthcheck.ipa.dna.IPADNARangeCheck: Insufficient access: Invalid
credentials

I tried to search for the critical message but nothing comes up. There’s a lot of GSSAPI
errors on all logs.
I tried to regenerate all keytabs of the system but it was a no go either:

Hello,
FreeIPA on CentOS 7.8 just stopped working and I’m unable to fix it by myself. After
reading a lot of threads here on the list, it appears that I’ve the same issue as this
topic:
https://www.mail-archive.com/freeipa-users@lists.fedorahosted.org/msg0550...
Since Kerberos is apparently not working as expected, I cannot use FreeIPA and none of the
services are working correctly. Following the debug guide I was able to at least start
named with single authentication to further debug. (Workaround 1 of
https://docs.pagure.org/bind-dyndb-ldap/BIND9/NamedCannotStart.html)
And now I’m stuck on item 5 of the same manual.
