It is touched on here:

https://wiki.samba.org/index.php/Setting_up_Samba_as_an_Active_Directory_Domain_Controller#Parameter_Explanation

It is quite simple, the realm is the DNS domain name in uppercase, so
in your case, the DNS domain appears to be 'duck', so the realm must be
'DUCK'

You don't appear to have provisioned with the realm 'DUCK', so it will
probably be easier to re-provision.
