coturn cannot open log file

[Sven Dörflinger]

Hello,

I want to save my coturn logfiles in the follow directory:
/var/log/turnserver

In the config /etc/turnserver.conf I set this:
log-file=/var/log/turnserver/turn.log

Follow log entry I can see in journalctl -u coturn:
ERROR: Cannot open log file for writing: /var/log/turnserver/turn.log

The directory has the rights:
drwxr-xr-x 2 root root

The package coturn has this version:
4.5.1.1-1.1ubuntu0.20.04.2

I use Ubuntu-Server:
Description: Ubuntu 20.04.3 LTS
Release: 20.04

My expectation is that coturn wright the logfile which like set in the configfile

Err, on this Ubuntu version coturn runs as the user 'turnserver'.
chgrp turnserver /var/log/turnserver should fix it.
And no, coturn should not create a directory in /var/log.
So this bug is not valid IMO.
