I coulnd’t find a similar issue yet, so please bear with me on this.
When trying to connect to the CardDAV folder on our CommuniGate server via https, i get a reproducible “error 401 access to this account is disabled” failure. (regardless of Preemtive auth or not).
The URL and login credentials i am using are correct and working flawlessly when syncing contacts with a Thunderbird Carddav-plugin.
Is this a general incompatibility between DavDroid and this kind of server, or is there anything that can be done on the client side to get the login to work?
