Over the weekend I installed Zoneminder from the plugin system, added some cameras, then started following instructions of the setup documentation. Then livestream stopped working. After battling through an uninstall reinstall (hint, you have to restart FreeNAS between) I found this really helpful article to fix the problem. There's something broken in their authentication system. If you enable authentication (OPT_USE_AUTH ) - obviously important - then set you have to set AUTH_RELAY to "none."
