> {code}
> *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.
