Thank you but that is already in place. I have the same issue on both Windows 10 and Windows Server 2016 and 2019.
You need user-level access control, using
Password file = ...
what are the pre-requisites to automatically fill the Author and Author Email fields. The documented method:
Subst Author = $long_name from $remote_host
Subst Email = $user_email
in the elogd.cfg file does not seem to work.
(I see it works here on this platform)
