I don't know if this bug has ben discussed before but i found it by chance the day before...so her
e it goes:
Let's say u have two accounts in one system which is running sun 4.x .
You login with the first one and then you do this: /bin/login -p (the second account).
it asks for the pass,u give it you login and you exit.
The result is that the first account becomes invisible and the second one is stck doing nothing an
d u are in with the first one..

[ try keeping your lines to 70 or so cols ]

Yep, that's why Solaris 2.x login will complain "no utmpx entry, must login
from the lowest shell level" or some such.

A simple fix for SunOS 4.x is:
        chmod u-s /bin/login

(Let people use rlogin/su if they want to use another account temporarily)
