There's a bug in Net_LDAP3 used by Kolab Webadmin
I'm using up2date packages from kolab-webadmin (commit 180a93bcd7d6 ) and php-net-ldap3 (commit 39a754269fe6)
Here's the Fatal Error message
[25-Mar-2025 22:46:58 UTC] PHP Fatal error: Uncaught Error: Cannot access private property LDAP::$domain in /usr/share/php/Net/LDAP3.php:970

thrown in /usr/share/php/Net/LDAP3.php on line 970The Problem:
The method Net_LDAP3::entry_find_by_attribute() tries to access an undefined attribute $this->domain (as for Net_LDAP3).

This attribute ($this->#domain) is defined as private

Variante 1:
A variable used in Net_LDAP3 (which is not an abstract class) should be defined as protected.
Variante 2:
The use of the undefined variable $this->domain in a debug message should be removed or change somehow.
Workaround (lib/Auth/LDAP.php) ... not ideal, but at least it doesn't throw a Fatal Error anymore.
/**
