List of calendars without login

Hi!

I was playing around with DAVdroid on my phone and my calendars on Nextcloud. I tried to add a new account in DAVdroid. There I noticed, that I get a list of all my calendars in the debug log, even when I had a typo in my password. So I tried again with an arbitrary (non-existent) username and password. Even in this case, I got a list of the calendars on my Nextcloud.
Is this the expected behavior? I don’t think, I want anybody to see the names of all my calendars.

What do you think?
Thanks for your input!

Can you share this on https://github.com/nextcloud/server/issues and share also your configuration?

Thanks for your reply. I will share it there.
Which configuration exactly should I give?
