I'm trying to sync with a yahoo calendar (beta) via calDAV, following
the note here:
<http://help.yahoo.com/l/us/yahoo/calendar/yahoocalendar/sync/sync-05.html>
but the calendar in Lightning is said to be "momentarily unavailable",
and sometimes a window pops up to ask a Zimbra username and password.
Lightning 0.9
TBird 2.0.23
MacOS 10.6.1
Does it ring a bell ?
The following post has additional hints, maybe they help:

Unfortunately no.
As it turns out, I am not prompted for my password upon finishing the
creation steps.
