Is there a way to add Dav addressbooks inside Usermin?
or/also:
Is there a WebDav server integrated with Virtualmin, that can be used for contacts or calendars?
(I tried following this guide, but I don’t seem to have a “Dav login plugin” listed among server features, nor any of the other entries indicated in the guide)
You definitely don’t want the old Virtualmin DAV plugin. It used Apache mod_dav, which is simply not fit for purpose (for anything).
Nope. But, Virtualmin Pro has a NextCloud installer, which does have WebDAV support, and seems to be what most Virtualmin users use when they need calendar and similar.
It would certainly be a great feature. Would allow me not to install any extra webmail client such as Roundcube or Rainloop. Usermin has got everything I need, except for this.
