Linux : Unable to configure Multi-User : 'Test Connection' buttons stay deactivated

[Touffman78]

Hi,

Autopsy v4.22.1 in Ubuntu 22.04
Wanting to test Multi-User cases on Linux, I can't configure things in the Multi-User configuration Dialog : even after entering parameters, the 'Test Connection' buttons remains deactivated and thus the OK button also remains deactivated :

As the configuration is OK under Windows, I then copied the 'ExternalServicePreferences.properties' file from Windows to Ubuntu as-is and the configuration Dialog is now OK and Test buttons are activated (and multi-iser cases are usable).
