>Description:
The login binary is invoked as "login -p user" once the user enters a 
username within the "login:" prompt to bring up the corresponding 
"password:" prompt for that particular user.

This causes some problems with multiple logins.  login can retry logins 
many times.  However, the same username as the first login attempt shows 
up.

>How-To-Repeat:
In a console, attempt to login with a bogus user/password.  Then, login.
Look at the corresponding login process running as root.  It will show up 
as login -p bogususer instead of the correct user.

>Fix:

Perhaps rewrite argv each time a login is attempted such that it always 
appears correctly.
