LDAP: In Distributed/MSP Setups, Test AD/LDAP Connections on the Effective Remote Site

In distributed and MSP environments, it is currently not possible to test the effective LDAP connection of a remote site from the central site. This becomes problematic when the central site itself has no network access to the LDAP server (e.g. Active Directory).

Background: If the configuration is set so that the remote site itself establishes the LDAP connection, there is no way to test whether this connection is working as expected from the central site. If the remote site is also located in a different network segment and only the remote site can reach the AD/LDAP server, administrators are effectively left without any way to validate or troubleshoot the connection other than checking the log files directly on the remote site.

Every AD/LDAP connection should be tested from the location where it is actually established.

Proposed improvement: Add the ability to execute the LDAP connection test directly on the configured remote site and return the result to the central site UI. This would significantly simplify troubleshooting and validation in distributed environments.
