Multiple Caldav calendars in Thunderbird Lightning auth problem

If you try setup multiple caldav calendars with Thunderbird Lightning hosted at the same CalDAV server you might get into trouble, because Thunderbird does not seperate the auth ( user/pass ) for each calendar url.

The workaround is to set parameter calendar.network.multirealm in Thunderbirds config editor
