Here it is (the summary). I have collected enough responses to tell that
/sbin/sulogin is not dangerous despite its ominous name, only its messages are

Thanks to Casper Dik, domahony, yann, Salehi Michael E, Iain Rae, David
Mitchell, Ronald Loftin, Tim Carlson, Richard Butler.

To the latter goes the prize for clarity about the message :

which I do get on our 2,5.1 systems with standard security (other said on 2.7
only root can issue it, but we have good reasons to stay with 2.5.1).
