Problem Description: 

30-Nov-92 Bug Fix 1031926 and refit to 4.1.2 4.1.3.
REXD/ON CAN DEADLOCK AND HANG

08-Nov-91 bugfix 1073436 Rev -02 
Any application using the syscall getlogin()  as executed from 'on -i' 
fails to retrieve user login from /etc/utmp  on 4.1.1 system.

04-Nov-91 bugfix 1069208 Rev -01
Since 4.0 rpc.rexd fails to log utmp entry properly. 
This causes syscalls which get user info on the server to return NULL, and 
programs which extract user information from /etc/utmp are useless. You 
can't tell who is on the system without doing a 'ps ax' and your can't tell
from which system they are coming from. System accounting utilities can't
tell what users are using their systems.
