[This is the first of several messages that have been in my backlog.
With changing jobs and trying to get net feeds established, I haven't
had time to do mod.os.unix (soon to be renamed something like comp.unix).
My apologies for the long delay.  I will include a "Posted:" header line
to indicate the date the posting originated for the backlog messages.

I am attempting to write a new getty to run on an IBM RT running
AIX ( SYSV ).  The client for our package wants a friendlier logon
screen based upon curses.  They want two methods of logging on.  
If they give a userid/passwd combo then they will enter into our 
package. If they enter UNIX for the userid they want to get a 
regular unix login.  
 
My problem is that when I exec '/bin/login', login only prompts 
for the userid, and always lets the user in without asking for
a passwd.  The best I can tell is that '/dev/tty' is not being 
associated with the control group.  The reason that the user is
not prompted for a passwd is that 'getpass' tries to open '/dev/tty'
and when it can't it return's NULL which login is not expecting.

Can any body validate my observations, and hopely tell me how
to attach '/dev/tty' to the control group.
