AuthSettingsController: assume 'auth_plugins' option exists In formglobals, the provided 'auth_plugins' default value is always replaced with the real database value, returned along with other plugin settings by Setting.get_auth_settings. We can safely assume that the database value exists, since not only does db_manage initialize the 'auth_plugins' option upon database creation, but other authentication modules already assume its existence. For instance, Settings.get_auth_plugins() is equivalent to Settings.get_auth_settings()['auth_plugins'] except that get_auth_plugins will throw AttributeError, not KeyError, if the 'auth_plugins' key does not exist in the database.
