I was also stuck on how to get a link to the ICS calendar to work since
you always need the username and password. I found a similar problem in
the user letters in the sogo archives and they suggested putting into
cron a script to copy the calendar.ics to a public place. Works nicely
actually.
Then I realized you can always include the username and password in the
link. The format is
http://username:[email protected]/dav/user/Calendar...... It's nice to
avoid using cron.
In the application I am using, this technique works perfectly. I am
showing my calender in my wordpress web page using amr ical events
plugin. Take a look if you want. http://pingsteskilstuna.se/kalender/
