[Samba] Kerberos errors during ads operations

[Ryan Bair]

I was attempting to view enctypes of various principals on my domain after
getting some errors like "KDC has no support for encryption type" on a DC
running Samba 4.7.6 with MIT KDC .

Running `net ads enctypes list MACHINEACCOUNT$` gives an error:
kinit: Client 'WORKGROUP at AD.DOMAIN.NAME' not found in Kerberos database
while getting initial credentials

What could cause this error?
