There is no 'local Administrator', the domain user Administrator is
mapped to the local user 'root'. So if the domain user 'Administrator'
has the password 'thispass' and maps to 'root', who has the password
'diffpass', then the user will be rejected because the user is known
(root) and the password is wrong (thispass).
