Dear Maintainer,

Fresh installation of Debian Trixie with phpldapadmin.

The main frame body is not rendered. The following error is logged:

PHP Deprecated: htmlspecialchars(): Passing null to parameter #1 ($string) of type string is deprecated in /usr/share/phpldapadmin/lib/HTMLTree.php on line 101

Workaround: Change line 101 in /usr/share/phpldapadmin/lib/HTMLTree.php from:

htmlspecialchars($server->getContainer($base->getDN()))

to:

htmlspecialchars($server->getContainer($base->getDN()) ?? '')

After this change, the main frame renders correctly.
