* This script displays the LDAP tree for all the servers that you have
2009-06-30 09:24:29 +00:00
* 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:
*
2009-06-30 08:05:37 +00:00
* tree.php#3_dc%3Dexample%2Cdc%3Dcom
