I don’t know, but generally I check my error messages ?

Critical: Check kerberos authenticated DNS update (on DC Master)

I upgraded to 4.3.0 and I checked with System Diagnostic my DC Master server: Critical: Check kerberos authenticated DNS update Errors occured while running `kinit` or `nsupdate`. `kinit` for principal dns-hostname with keytab /var/lib/samba/private/dns.keytab failed. I ckecked with: kinit --password-file=/etc/machine.secret $(hostname)\$ klist and everything is OK Do you think is false positive (like here Critical: Check kerberos authenticated DNS update) even if is on a Master DC role?
