/*
* tree.php
* This script displays the LDAP tree for all the servers that you have
* in config.php. We read the session variable 'tree' to know which
* dns are expanded or collapsed. No query string parameters are expected,
* however, you can use a '#' offset to scroll to a given dn. The syntax is
* tree.php#<server_id>_<rawurlencoded dn>, so if I wanted to scroll to
* dc=example,dc=com for server 3, the URL would be:
* tree.php#3_dc%3Dexample%2Cdc%3Dcom
