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/msg05501.html

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.

Any ideia on how to fix this?


PS: Before the workaround named-pkcs11 fails to start with the following error:
