title: "Last signed in" property in DomainUser class (Google Apps script)
body: <p>I wonder why I can't find the "Last signed in" property in the new and very useful Domain services of Google Apps Script.
  In the administrator console of Google Apps Education, every user is listed with a "last signed in" column, but no trace of this property in the DomainUser class !
  Any ideas ?
  Thanx
