Endless Login loop

Steps:

1. I open Ground Control from the System-Preferences menu.
2. I enter my launchpad username and login data
3. The launchpad seems to log me in, shows the launchpad page for about one second, then closes and goes back to the login screen.
4. If I enter my username and login the application continues in an endless loop.
