I just ran some tests, and yes there is definitely some slightly odd interaction going on between the various ways of enforcing ssl and surgeweb calendaring. You actually do not need to put any port numbers in g_url_alias, but doing so does change the behaviour / reported errors as you have found.
There is a surgeweb level setting to enforce ssl on surgeweb web requests:
https_required true
If this is set surgeweb will detect the need for ssl and connect to caldav / user.cgi etc using ssl. This can be set on surgeweb customisation page or any of the surgeweb config_*.dat files.
As it stands if this is not set and just g_ssl_require_web is used then surgeweb tries to connect to caldav on the non ssl port and it fails with a variety of ssl related and seemingly unrelated error messages.
If you use just https_required and do not use g_ssl_require_web at the surgeweb level any incoming requests on the http port will be automatically redirected to the https port. This configuration would mean that you do not have strict ssl enforcement on the other surgemail web interfaces.
Anyway, let me know if the addition of "https_required true" does the trick in solving your calendaring issues.

I've gotten past the first error message now (550 Secure https: link required for webmail) when trying to access the CalDAV calendars in SurgeWeb.
Previously, the "Ports" field was empty for all the alias entries on the g_url_alias page. I never thought to change that, as SurgeWeb webmail has been working fine AFAICS.
I changed various settings, but it was after I put "443" (my secure SurgeWeb port) in all of the fields that the original error (Secure https: link required) went away.
Now I get a different error when I click on the "Calendar" link in the left column in SurgeWeb, or the "Configure" button in the left Calendar pane:
Cal Request Failed: Error downloading
/usr/local/surgemail/surgeweb/work/ferebee.net/c/f/cf/tmp_xxx_xxxxxxxxx_20270873 0/4096 (1)
Again, the right pane shows "CalDAV calendars" and an empty list of "Your Calendars" and "Shared Calendars". My primary need at this point is to be able to configure the sharing.
Best,

I'm trying to set up CalDAV for Mac and iOS users on SurgeMail 6.3d72.
To grant shared access to calendars, I understand that we need to use the Calendars pane in SurgeWeb. However, it doesn't display any calendars. Instead, it shows the error message
Cal Request Failed: 550 Secure https: link required for webmail - change http to https in url
This is undoubtedly caused by the fact that I have set up my server to redirect all HTTP requests to the webserver domain to the HTTPS login page.
Calendar sync for a single user between OS X 10.8.3 and iOS 6.1.3 seems to work fine with automatic setup. Access to webmail also works as expected.
Where can I change the URL for calendar access from SurgeWeb, as suggested in the error message?
