To enable this, you must have a registered account on the server and have a premium account [An paid account bought from the official Minecraft website].
Do not use the auto-login feature if you have a cracked account. We will not assist in recovering your account under any circumstance should you fail to ignore this warning.
Once registration is complete, a GUI will open and you can simply click the respective blocks labelled Premium or Cracked. If this GUI does not open, try re-logging.
