I would be surprised if someone hasn't encountered this already, but I
haven't found any discussion of the nature of this problem.  I run RehHat
5.0.  If a user makes a mistake in the login process such as the
following:

login:  mistake
password: xxx
Login incorrect!

login:  username
password xxxx

bash$

a ps will show, among other things,

2333 /bin/login --mistake.

Since some users accidentally type their password at the login prompt,
this is a concern.

Is this a well known problem and what should I do to fix it.

Thanks.
