Can you check if the certificate in /var/kerberos/krb5kdc/kdc.crt has been
renewed?
# sudo openssl x509 -noout -text -in /var/kerberos/krb5kdc/kdc.crt
and check the values for Validity: Not before / not after.

The page https://www.freeipa.org/page/Troubleshooting/PrivilegeSeparation
provides troubleshooting steps that could help you narrow down the issue.
