sabnzbd not using USER

[MechEng70]

Have been able to get the openvpn portion running, however the error is local to the sabnzbd user.

Here is the command to start the docker:
sudo docker run -d --name sabnzbdvpn -v /home/plex/.sabnzbd:/config -v /etc/openvpn:/etc/openvpn -v /etc/localtime:/etc/localtime:ro -v /etc/passwd:/etc/passwd:ro -v /etc/group:/etc/group:ro --device=/dev/net/tun -p 8800:8800 -e "LOCAL_NETWORK=172.16.4.1/23" -e USER_NAME=plex -e PUID=1001 -e PGID=1001 -e DOWNLOAD_DIR="/home/plex/Downloads/complete" -e INCOMPLETE_DIR="/home/plex/Downloads/incomplete" -e OPENVPN_CONFIG="torguardSF_UDP.conf" --cap-add=NET_ADMIN mumiehub/sabnzbdvpn

Here is the log:
`adding route to local network 172.16.4.1/23 via 172.17.0.1 dev eth0,
Error: Invalid prefix for given prefix length.,
Setting owner for Folder paths to 1001:1001,
,

Sabnzbd will run as

User name: plex
User uid: 1001
User gid: 1001

OPEN VPN WORKING

The 'abc' user is hard coded, shouldn't this be overwritten by the plex user that is set?

[MechEng70]

how can I hard code the 'abc' user on ubuntu?
