Hello Community, this my first post around here because owncloud worked like a charm on my two windows devices and my Linux Mint xfce device… I hope you can help me solving my problem 
Expected behaviour
Owncloud should ask for password and username once and then store them.
Actual behaviour
After a reboot of the computer the client always wants to authorizes through the browser. (When setting up the client, It did not ask me for username or password, only for the server address).
There is an entry in my kdewallet (Contents tab) but in the Applications tab there is an entry only in the upper field (“These applications are currently connected to this wallet”) and not the lower one (“These applications are authorized to acess this wallet”). This is weird, because I actually granted access to owncloud multiple times.
Syncing of my folders works fine once authorized.
Steps to reproduce
- (Re)boot the computer
- (start the owncloud client/wait for it to start)
