[Samba] Kerberos Authentication Problem with MacOS

[Mark Cogan]

I've run into the same issue.  Current Samba and MacOS will connect with
username / password from my MacOS Finder, but Kerberos doesn't accept the
connection.  I do see the Kerberos ticket getting generated.  The same
MacOS system will connect via Samba to older versions, so I'm wondering
what the disconnect is or if there is a new configuration parameter I need.
