AUTH

[kappsegla]

This server is supposed to sit on a secure network and not being exposed on internet. Therefore the communication will by default happen on an unencrypted TCP connection. If we want to have some form of security we can add a password that must be sent on a connection before issuing any commands.
AUTH

If the password is valid return
+OK\r\n
When password is invalid return
an error

Password could be configured from a config file or from an environment variable for docker support. If no password is set, no AUTH command should be needed before sending other commands on a newly opened connection to the server.
