I cannot restart guacd right nog as the server is in use.

I'll update when this has solved my problem.

Though you'll still need to wait for the server to not be in use, what you need to restart is Guacamole (by restarting Tomcat), not guacd. Restarting guacd will have no impact on auth; it is independent of that.
