I want to create a login page in HTML which is hosted on apache server.
The login page first authenticate the user and then directed to a form which in turn run a script on the server.
I want to make login page without php or jsp.
Please advice.

one option is to use Perl and CGI

what if I dont want to use either.. cant I do only using HTML page and some scripts in unix...
Please discuss the code.

You can. Apache doesn't care what language CGI programs are written in, as long as the execute. I think I even saw a complete blog written in nothing but bash. But the question is: Even if you can, why would you want to? As a learning exercise? Because there's nothing available on the machine better suited for the task?

I want to make a login page and use shell script to authenticate but I dont know if user want to change his password then how wil he do it.
I couldnt able to write the code for authentication. Would I have to hard code it??

As I said, CGI can be written in anything runnable, leaving me with the question "What exactly do you want to do"? Could you flesh out your specifications a bit, and tell us what points you have problems with?

only want to make a login page, which authenticate the user and user can change its password when he wants to. Admin can be able to add users too.
Do you need more information?? I am a new user in this field so I told you what I want to do.
I had some html forms which user can be alble to access only after authentication i.e after login in.
can you discuss some code in shell scripts for this purpose.
