Probably a bug - I don't recall if/when anyone actually tested that code path. I'll have a look...probably in the hostfile parser.
What version are you using?

Oops sorry I made the test too fast: it still does not work properly with several logins:
I start on user1's machine:
mpirun -np 2 --machinefile machinefile.txt MyProgram
and I got :
user1@machine2 password prompt ?! (there is no user1 account on machine2...)
My problem is still open... why is there a connection attempt to machine2 with user1 ...
Has somebody an explanation ?

OK, it works now thanks. I forgot to add the slots information in the machinefile.

It is the exact same syntax inside of the machinefile:
