[ale] Adding a new document root

[Chris Fowler]

I'm trying to add a document root to an existing CentOS 5.X box that is
running tomcat and some JSP (not my stuff).  I've done this before but
in this case I want to add htpasswd authentication.   Can someone give
me a pointer on what to modify in this conf file?

Alias /li /opt/link-interface   
Alias /link-interface /opt/link-interface   
<Directory /opt/link-interface>
    AllowOverride All
    AddHandler cgi-script .pl
    Options ExecCGI Includes FollowSymlinks
    Order Allow,Deny
    Allow from All
</Directory>
