Security in directory Root

Dear guys, this is my question.

In my server, when i put a password in my root path, and try to access
a sub path by the network, all the sub path request password that
corresponding of the password from root path. So, if i set a sub path
with password, it`s request the password from root path and next, the
password from the path that i set. I would like to make a password
just for the subpath without request the password from the root path.
Is there anyway?!

Thanks who can help me!


Regards.
