Dears,

I try to connect the iCal on MacOs an it won't work. I receive the following logs:

Attached is the mac os configuration dialog. I'm using mac os 10.14.3 (18D42).
Any suggestions on what I'm doing wrong? Username and password should be correct, as it works perfectly with E-Mail!

Thanks!

Looks like you have a trailing space in your settings:
PROPFIND /%20 HTTP/1.1

Make sure you remove it

Unfortunately this doesn't change anything :(

Well, after the initial request your client is supposed to provide credentials...

[markus.seidl@nttdata.com]

Hi!
The first description shows the Screenshot of the calendar application, which I'm using. The username and password fields are filled. Maybe I should have said something in the text.
So I'm using the standard Mac Os Calendar and the settings from the documentation, as shown in the screenshot. Username and password are filled.

Maybe you can give me an additional pointer?

[Mickael Guessant]

I wouln't be surprised that iCal blocks basis authentication on cleartext HTTP.
=> we should probably try to enable SSL in DavMail settings

You may also want to try with Thunderbird to confirm your settings and/or try to access calendar in a simple browser.

Hi!

Thanks! I tried it and it now works fine. Should have realised it sooner - thanks for the solution!

For anyone having the same experience, I did the following:
1) Executed "hostname" in the terminal and noted down the hostname returned
2) http://davmail.sourceforge.net/sslsetup.html chapter "Server keystore (Client to DavMail)" and replaced cn=davmailhostname.company.com with my hostname.
3) Updated the settings of davmail and started it
4) Accessed https://localhost:1080 with Safari (!) and forced it to visit the page. Which in turn will trust the self signed certificate on your system.
5) Finally connected with Calendar

Hope this helps someone else having the problem!

Thanks again!

[Mickael Guessant]

Thanks for your feedback.
