First try typing
login /?
and see if it is possible to specify the
password on the command line. No decent
system should allow it!

Next, try creating a file with EXACTLY the
keystrokes you need to enter in order to
log in. On my system (using Netware 4), we
can specify server and user name on the
command line. All I have to do is enter
my password and hit "Enter". So the first
thing I do is create a file named "login.txt"
with nothing but my password and a carriage
return:

---------
PaSsWoRd

---------

Then I create the batch file which logs me in.
It "pipes" the login.txt file into the actual
login command. Basically, this forces the login
command to take it's input from the login.txt
file INSTEAD of from the keyboard:

---------
type login.txt | login sanwfs1/ericp
---------

In the above example, sanwfs1 is my server,
and ericp is my user name. Now, if something
goes wrong with your login (say it tells you
your password expired and asks you for a new
one), you are screwed. Nothing you do to the
keyboard will work because the login command
ONLY looks at what you've typed into the
login.txt file. So you better type everything
you think you MIGHT need in there. You might
want to put a couple "N" characters in there
to answer "No" to any questions. Frankly, no
decent system should allow you to automate
your login! Any GOOD system will AT A MINIMUM
clear the keyboard buffer and flush STDIN to
force password entry from the actual keyboard.

Because your problem won't be as easy to solve
as the above suggestion, you might also want to
take a look at the "sendkeys.txt" file in this
same directory for more suggestions.
