I'll not give you concrete Apache config because

(1) I cannot test it from my environment
(2) I do not wish to encourage excessive spoon-feeding

Using authentication is a pretty basic area of Apache administration. You should be able to dig it up from other resources for exact details. I'll just give you pointers.

The main idea is, you first need to select the authentication mechanism - basic or digest authentication.

If your pages are served over HTTPS, that having a password essentially unencrypted will not be captured by eavesdropping, you can probably get by using basic authentication:
mod_auth_basic - Apache HTTP Server

If you need a bit more security, but a bit more tedious to set up, use digest authentication:
mod_auth_digest - Apache HTTP Server

Then you just plug one of the password stores for use with the authentication, in your case the LDAP one. You will then need configuration specific to LDAP.

This page essentially covers most of what you should know (concepts - you will need to find LDAP-specific info in other pages):
Authentication, Authorization and Access Control - Apache HTTP Server

Finally, in your Perl pages, check the REMOTE_USER environment variable. According to the CGI Specification, Apache should pass this username to you in case the user has been authenticated successfully. Do confirm this yourself.

If you use CGI object, you may retrieve it by $cgi->remote_user().

Template::Plugin::CGI(3)				User Contributed Perl Documentation				  Template::Plugin::CGI(3)

NAME

       Template::Plugin::CGI - Interface to the CGI module

SYNOPSIS

	   [% USE CGI %]
	   [% CGI.param('parameter') %]

	   [% USE things = CGI %]
	   [% things.param('name') %]

	   # see CGI docs for other methods provided by the CGI object

DESCRIPTION

       This is a very simple Template Toolkit Plugin interface to the "CGI" module.  A "CGI" object will be instantiated via the following
       directive:

	   [% USE CGI %]

       "CGI" methods may then be called as follows:

	   [% CGI.header %]
	   [% CGI.param('parameter') %]

       An alias can be used to provide an alternate name by which the object should be identified.

	   [% USE mycgi = CGI %]
	   [% mycgi.start_form %]
	   [% mycgi.popup_menu({ Name	=> 'Color'
				 Values => [ 'Green' 'Black' 'Brown' ] }) %]

       Parenthesised parameters to the "USE" directive will be passed to the plugin constructor:

	   [% USE cgiprm = CGI('uid=abw&name=Andy+Wardley') %]
	   [% cgiprm.param('uid') %]

METHODS

       In addition to all the methods supported by the "CGI" module, this plugin defines the following.

   params()
       This method returns a reference to a hash of all the "CGI" parameters.  Any parameters that have multiple values will be returned as lists.

	   [% USE CGI('user=abw&item=foo&item=bar') %]
	   [% CGI.params.user %]	    # abw
	   [% CGI.params.item.join(', ') %] # foo, bar
