Problems with LMS in Docker and Library Permissions

Hello. I am having problems with permissions on my LMS setup inside a docker container. I know enough to figure out that it is because of permissions but not enough to figure out how to fix it.

The setup that I have is LMS running in a docker container on a Raspberry Pi. The Raspberry Pi has an automatic mount of a Samba share from a hard drive attached to my router that is set up in fstab and works well on the Pi. I can access and open all shared files including the music directory and all the albums in it. The location on the Pi is /home/pi/ddwrt/ for the samba share.

The docker container for LMS has a volume mount from the music folder on the samba share to the /music folder inside the container (/home/pi/ddwrt/Music:/music). When I exec into the container (using the console feature in Portainer because its easier) as root user, I can access the /music folder. However if I exec into the container as the squeezeboxserver user, permission is denied to the /music folder.

When I run a music scan from LMS via the settings, I get an error. The line from the log is:
I've tried adding the squeezeboxserver user to the root group with but this didnt fix the issue.

One workaround that I found was to edit the /etc/passwd file and to change the squeezeboxserver user line to: but I dont think this is a good idea because I get warnings in the log telling me that Logitec Media Server should not be run as root and to try using squeezeboxserver user instead. Will or could this cause any issues? I dont want to run it this way becasue of the warning and I am worried that I might cause other problems.

Thanks in advance for the assistance.
