LDAP Integration of xwiki

Hello, Can someone please guide me on how to do the LDAP integration of xwiki. I am trying to integrate it with our company LDAP. I have gone through the url in http://www.xwiki.org/xwiki/bin/view/Dev/LDAPIntegrationAD My specific questions are 1) Are the only changes required in xwiki.cfg file or should we use the LDAP plugin code as well? 2) Once the changes are done, how does it work? If I access the home page, will it throw a popup for login?
