Cause
The issue has to do with the python built-in ConfigParser. It fails to parse multi-lined property vales unless there is a space added to the beginning of the additional lines

Solution
Fix the call to the ConfigParser to add the missing spaces (for internal use only). The data in the relevant config files are not altered
While making changes fix the logic in the Atlas security_status method to properly determine security status.
