[Samba] Problem since upgrade to 4.5.1

Just a though as I was passing in the neighbourhood:
does your Terminal Server have related SPN (ServicePrincipalName) created
on computer objects?

servicePrincipalName: HOST/W7AD-02
servicePrincipalName: HOST/W7AD-02.ad.domain.tld
servicePrincipalName: TERMSRV/W7AD-02.ad.domain.tld
servicePrincipalName: TERMSRV/W7AD-02

HOST/<hostname> should exist on all computers, that's just to be
thorough.
TERMSRV/<hostname> should exist on Windows you want to access through RDP
(if my little understanding regarding SPN is correct)
