Can't configure DAVDroid account with Synology

---

I don’t have a lot of time, but I will first have to run some test on other clients. It’s an account with access to WebDav/CalDav on my Syno you need, right ? If so, no problem. I’ll do my test, and then, I’ll send it to you.

Hi,
Any help is welcome, but don’t feel rushed by me. I’m using your issue to add information about mine.

I was checking whether my issue was already posted before writing a new one. Yours seemed similar due to the error message.
Since rfc2822 was asking for more information and a test account, I thought it might be helpfull to make one for my issue as well.
Maybe our issues are related and my test account can help solving them.

Hi,

Little update
Sorry, it’s a bit late, but I didn’t had time to do it before.

I ran some test, and it’s working fine on Thunderbird (with Lightning), but I still got the same error with DavDroid.

After testing a Synology device, I found out that for some reason, the current-user-principal is not returned, so that auto-detection of resources is not possible (and DAVdroid only supports resources which are automatically detectable).

I have looked for a way to report/discuss that with Synology, but I couldn’t find any way to contact them electronically except the contact form, which I can’t use because I actually don’t have an own Synology device and can’t register without serial number etc.

Follow up: https://twitter.com/davdroidapp/status/450018678957158400 & waiting for a response…

I have also read that it is possible to install OwnCloud (maybe even other CalDAV/CardDAV servers?) to Synology devices, which would work around this problem.

Also see https://twitter.com/davdroidapp/status/471652913082023936

Closing this for now, please report further problems directly to Synology.

Any news following this issue ? Did you received any feedback from Synology?
I’m actually in a similar situation: bought the davdroid app but can’t get it working due to this Synology issue.

Regards,

DAVdroid 0.6.12 now supports Synology, we have changed the detection code so that it doesn’t require current-user-principal support.

Thanks a lot, it will be useful

I wish Synology had corrected the bug on their side, though.

@TheDoctorII yes, would have been a lot easier if they did…
@henry-nicolas Can you maybe test the new version 0.6.12 (see https://davdroid.bitfire.at/configuration for configuration details) and tell us if it works for you?
