Message text

Cannot set group (GID %d) for user %s (UID %d)

Description

A proxy is typically started with root privileges in order to be able to bind privileged ports. After binding sockets, the user identity (real and effective UID and GID as well as the list of supplementary groups) is changed to some unprivileged user. If giving up root privileges fails, the proxy cannot continue.
