[horde] CalDAV setup

[Harlan]

Hello,

   I've been trying to get remote access to my calendars working.

   If I go to this URL:  https://www.mydomain.com/webmail/rpc/

     I get a listing of "services" that Horde thinks are available:

principals     Collection         2018-01-23T21:37:56+00:00
calendars     Collection         2018-01-23T21:37:56+00:00
addressbooks     Collection         2018-01-23T21:37:56+00:00
kronolith     Collection         2018-01-23T21:37:56+00:00
turba     Collection         2018-01-23T21:37:56+00:00
nag     Collection         2018-01-23T21:37:56+00:00
ansel     Collection         2018-01-23T21:37:56+00:00
whups     Collection         2018-01-23T21:37:56+00:00
gollem     Collection         2018-01-23T21:37:56+00:00

   However, when I click on the the link (name) for any of them, all I 
get is a 404/Not found error.


   Obviously, something in my settings are not correct.


   What do I need to change to make these work????

   What specific settings files you do you need to see to help answer 
this question????


Thanks,

Harlan...
