Sabre/dav - CalDAV and CardDAV server, alternative to Radicale.

[girish]

I use the one in nextcloud and it's being working OK for a couple of years now.

[necrevistonnezr]

@girish Does it reliably sent invitations via email if I add someone to a calendar event? Both on the web and when using mobile apps that sync to the NC calendar?

[d19dotca]

@girish I don’t necessarily want to have to deploy the full resources of NextCloud though just for one specific feature. But it’s an option for sure.

[yusf]

Why another one? SOGo works flawless for me and is already in the app store.

[d19dotca]

@yusf Because it’s always good to have options. Plus maybe it’s just me but I much prefer to have dedicated apps for tasks rather than deploying apps only to use the secondary feature set. Lastly, Sogo doesn’t work the way I want it to and I’m not entirely sure if it’s even fully RFC compliant either based on my experiences with it so far in testing. It does not work well for me with macOS or iOS standard apps, it is difficult to delete a calendar through the Calendar app for example if Sogo is the backend, but works fine with any other DAV server I’ve tried. Plus the example below:

Example with Sogo for all DAV needs:

• I can create different calendars but must use these same calendars for groups of Reminders/Tasks. I cannot have separate groups of Reminders/Tasks.

Example with Radicale for all DAV needs:

• I can create different calendars and can create separate groups for Reminders/Tasks, they are properly independent of each other.

I have to test this. Usually, I just use the calendar for myself.

For me it has worked flawlessly for years. I never have to sign in to the actual SOGo web interface, I just use macOS stock apps. It does however seem to link regular Calendar calendars with Reminder calendars though.

@yusf Does it reliably sent invitations via email if I add someone to a calendar event? Both on the web and when using mobile apps that sync to the SoGo calendar? Many caldav servers still have a problem with this quite basic feature.

I agree, it'd be great to have a robust CalDAV server that handles invite emails robustly. If that option is Baikal, I'm all for it. I definitely prefer SOGo for GUI but that bugs with invites mangling events (making the organize null) when I add an invitee and then not sending the email is very frustrating.

[christiaan]

Is Sabre/Baikal the same thing??

Yes, Baikal is sabre with a an admin ui

"Baïkal is powered by sabre/dav, while offering an administrative interface for easy management."

It sounds to me that if Sabre/dav is to be added, Cloudron should add the full Sabre/dav | Baikal stack with GUI. We are using Fruux (who are the main users/sponsors of Sabre/dav | Baikal) and have been having all kinds of issues with syncing of CardDAV. CalDAV has been quite a bit better for us (production quality) but with complaints from the team of occasional issues.

Part of the issue is Apple's deliberate sabotaging of CardDAV/CalDAV to drive users to iCloud. We are never going to use iCloud (sharing our calendars directly with the NSA/CIA/FBI).

Even if it's not the fault of Fruux/Baikal developers, we still need working MacOS and iOS sync. This means we are looking for a CalDAV/CardDAV stack which programs defensively for iOS and MacOS. I'm going to ask NextCloud users again about reliability of NextCloud with Apple devices.

If Sabre/dav | Baikal won't work any better than Fruux, I'd vote against adding this stack as I know it doesn't sync reliably.

Nextcloud is also just using Sabredav under the hood, so the probability of it working differently are slim.

As a macOS and iOS user myself, that is why I suggested this CalDAV/CardDAV stack (Sabre/dav) because from my readings at least (at the time I suggested this) it seemed to be the most compatible and complete DAV solution. The current Radicale stack states explicitly that it does not intend to support the full RFC for CalDAV and CardDAV and wants to remain as "simple" as possible, which unfortunately causes issues for those who need some extra features like calendar sharing and better support for more devices / apps. If you're aware of others that are better, please add them to the App Wishlist.

Works fine here without hiccups.

[ruihildt]

I would definitely welcome a solution which is working without Nextcloud, especially as Cubby matures.

I tried Radicale and ran into problems. Went back to using Nextcloud which we find very reliable, apart from this alert badge in Calendar on Macs. The thing is it doesn't seem to actually affect anything. Everything works as expected despite this message.

The server responded with an error.
The request for account “beehive.archi” failed.

The server responded with
“501”
to operation CalDAVUpdateShareesQueuableOperation.
Try Again | OK

@foliovision actually I do seem to need to click on the alert I'm getting and click OK to get it to sync properly.
