Limit number of SSH connections per user to 1

I want to successfully limit the number of SSH concurrent connections to 1 per user.

(without having to setup this limit on the port).

Maxsessions and maxlogins don't work.

All linux distro seems to allow concurrent ssh connections, unless you use iptables on a specific port.

I need to use 1 port only, and set this limit per user (basically for every user, except the root).

So John can have 1 concurrent connection max.

Lucy 1 concurrent connection max.
