It’s IMHO poorly documented (in terms of visibility).

Since it is not enabled by default, you have to edit your config file with the ‘[sharing]’ section. There are two types, by map and token to conform to different usecases. There are also two different storage types, csv and files. Personally i chose map and csv way.

After adding your config and restarting the server, in the gui you can find a new button to share next to your calendar / carddav and in the bottom right menu an entry to accept invites issued by others.

I previously shared with the symlink too but since this update i got rid of it and used this new system and, well, it works for me (i’m sharing ro only calendar but you can assing [limited] permissions too).

Well, it was officially and well supported before. It is just awfully complicated and unintuitive. So much that I decided to vibecode a GUI to manage my sharings with family members.

Now that I did that, Radicale’s native sharing and permissions system makes more sense but is still unusable by most people in need of a simple sharing / editing / per user permission management.

Here’s an example:

[admin-root]
user = user1
collection = 
permissions = R

[admin-principal]
user = user1
collection = user1
permissions = RrWw

[admin-full]
user = user1
collection = user1/.*
permissions = RrWw

[admin-read-user2-root]
user = user1
collection = user2
permissions = R

[admin-read-user2-cal1]
user = user1
collection = user2/cal1
permissions = Rr

[admin-read-user2-cal2]
user = user1
collection = user2/cal2
permissions = Rr

[user2-root]
user = user2
collection = 
permissions = R

[user2-principal]
user = user2
collection = user2
permissions = RrWw

[user2-full]
user = user2
collection = user2/.*
permissions = RrWw

[user2-read-write-user1-cal3]
user = user2
collection = user1/cal3
permissions = RrWw

[user2-read-user1-cal4]
user = user2
collection = user1/cal4
permissions = Rr

[user2-read-user1-cal5]
user = user2
collection = user1/cal5
permissions = Rr

[user2-read-user1-cal6]
user = user2
collection = user1/cal6
permissions = Rr

For anyone curious about my vibecoded thingy, I just switched the repo to “public”. It’s in French, but can be instructive for anyone willing to understand more about how sharing and permissions work.

As for Radicale v3.7, I’ll need to check what has changed. Thanks for sharing

I have been using the link to share… Its not a weird thing, just a filesystem link between radicale users…

But if now it’s easier to manage, good to know… Let us know!
