Tvheadend

Hi,

I've installed Tvheadend inside a docker container from the docker hub, on my Raspberry Pi 2.
Please find more information about the container here, if needed: https://hub.docker.com/r/forumi0721alpinearmhf/alpine-armhf-tvheadend/
My docker host system is OSMC (https://osmc.tv). I use the docker container, because I would like to have a portable version from Tvheadend, for example if I have to rebuild the host system or to transfer it easy to another Raspberry Pi. The persistent Tvheadend data will be saved outside the container in a mounted Folder from the host system conf.d (-v /conf.d:/conf.d \).

My problem is that, after I've set a password I can't login again on the web Interface with the created user. I've read here in the forum that this can be a problem with the access permissions, so I changed the access permissions inside the docker container and also in the host system for the conf.d folder, but in vain.

in the host system for the conf.d folder
chmod 755 conf.d -R -v
.
.
mode of 'conf.d/tvheadend/passwd' changed from 0700 (rwx------) to 0755 (rwxr-xr-x)
mode of 'conf.d/tvheadend/passwd/7006a89da0ba0969941e8b912de9749a' changed from 0600 (rw-------) to 0755 (rwxr-xr-x)
