This works for me under 3.3 and 3.4.  It also worked for the person
who asked the original question.  True, the manual does not document
the ".username" part of the argument.  In fact, it even gets the
description wrong of what name has to be in which .rhosts file.
Unless this feature is new in 3.3, I don't know why it didn't work
for you.
