In the case that I want to set-up two CalDav calendars in Thunderbird, which reside on the same server but in different paths as they belong different users (e.g. https://xx.xx.xx/abc/calendar and https://xx.xx.xx/def/calendar), Thunderbird uses the same user credentials for both calendars. This is fine, if one has access two both paths, however if the paths are associated with different user accounts, the second calendar is not assigned. Any suggestions?
