/**

|
* 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
