A realm is the name of a database that contains encryption keys of user
and service principals. A domain is the name of a database that contains
all persistent information about users (minus their encryption keys).

There is a 1:1 mapping between a user principal name and a SAM account
name but the realm and domain are not required to be the same. For example
in a large company you might divide up your domains by department with
a single realm.
I'm not sure if one form is to be favored over the other though.
