InfluxDB max user`s password length

Apparently Microsoft is not alone when it comes to utterly retarded design decisions. A few years ago when signing up for a Microsoft account I discovered that for some reason they enforce a maximum password lenght of 16 characters or something around that. Well, InfluxDB not only does the same thing but also silently fails to create the user account when the password is considered too long. Took me at least half an hour to figure out why this piece of trash kept vomiting {"error":"authorization failed"}. …

This might be useful to keep power consumption under control but is actually harmful for disks that run 24/7 (WD Red for example).
