Check_MK Werk 5944: Fixed broken HTTP header auth for not yet existing users

ID: 5944 Title: Fixed broken HTTP header auth for not yet existing users Component: Multisite Level: 1 Class: Bug fix Version: 1.5.0i4 This was broken since ~1.5.0i3. When a user which has not been created in Check_MK before is being authenticated using the optional HTTP header authentication and logged in using the "default user profile", some host- and service views were not working as expected. They were showing some exception like "KeyError: u'<USER>'". A workaround in the affected versions is to create the user accounts before the user try to access the GUI.
