Re: [Samba] samba 4.6.0 dc provisioning fails with exception


I found the cause. It was the default kerberos config on CentOS: /etc/krb5.conf

Please add to the wiki page:


that before provisioning we should remove this file.

It wasn't confusing only for me, as the resolution I found was in bugzilla:


Maybe you could add some error description for this exception during provisioning, so the installing person is not totally in the dark?

Best regards,

Below is the output. I would have filled bug report, but the "New Account" in bugzilla is not working also :(
