Bad URLs in Advance User Guide (Web Page)

Authorization section on Directory ApacheDS Advance User Guide points to a wrong URL. accessing the directory I saw that the actual link is:
http://directory.apache.org/apacheds/advanced-ug/4.5-authorization.html
And it is listed as:
http://directory.apache.org/apacheds/advanced-ug/4.2-authorization.html

All nested resources in Authorization section. also point to 4.2 while the resource is named 4.5. According to the guide it should be 4.2 though.

Would recommend revising the whole guide though.
