LDAP Authentication Debug

I have recently installed v6.4.2 in a dev environment as I was particularly interested in being able to debug LDAP issues. The instructions that you have for using LDAP Debug View are not very clear as to how to use this. Can you perhaps elaborate on the LDAP Debug View? The images are also not showing on that page. Thanks.

I’m noticing the same thing: I can’t find the LDAP Debug area on my OpenSource installation. What are the steps to make it appear?
