Hello OH community,
after I have deployed the latest image.
(SUCCESS: openHAB updated from 4.1.1 to 4.3.3)
OH4 is running without any problems, except that my administration user and password in the UI do not work anymore.
Are user/password (/auth) stored in the container or on the volume?
What did I do wrong during the upgrade?
Many thanks and greetings
Sebastian
It depends on what volumes you’ve mounted. If you’ve followed the docs, they should be stored in a volume. Inside the container you can find the files they are stored in under /openhab/userdata/jsondb/users.json.
If that file is missing or corrupt, you can find an automatically created backup under /openhab/userdata/jsondb/backup. By default OH will make a backup of any file in the JSONDB folder upon a change and keep up to five versions of each file.
Hello Rich,
Thank you so much for your help.
I am so ashamed after checking the users.json file as you describe.
I realized that the username is lower case. 
What can I say, everything is working as desired.
Thanks again for your help.
Greetings
Sebastian
