Sometimes (as in my case) the email of a user cannot be easily constructed from the SVN login name or the active directory login name. When using AD as the authentication mechanism, it would be nice to look up the user's email address from it for all notifications sent out.

This avoids requiring people from configuring LDAP Email Plugin as a helper to get this working properly which admittedly defeats the whole purpose of having a nice simple AD plugin so we don't have to deal with the nightmare of configuring LDAP against AD.
