Login problems with System V/386 3.0e

[David Kozinn]

I seem to have run into a strange problem with logins on my System
V/386 (version 3.0e) system. I have no problem logging in to any
account from any of the consoles, but I can't seem to log in on any
account that has a password when dialing in remotely. What I try to
do that, I get the usual "Login incorrect" message but BEFORE I even
get the Password: prompt.

A bit of further experimentation showed that when I dialed in
remotely (on an unpassworded account) and tried to even su to a
passworded account, the su just came back immediately without an
error message, without asking me for the password, and without
changing users.

Is there some security feature that I've inadvertently turned on?
This makes leaving the system up for me to dial into remotely just a
wee bit difficult. Thanks in advance.
