Forbidden message in ADS connection test

I face this issue and found the exact solution to fix it.

Error- ADS status Status HTTP Response 403

Solution- 

Open your Visal Admin and to go Security provider and choose the Policy Configuration "com.sap/com.sap.engine.services.webservices.tool~wsnavigator". 

Select the tab "Security Roles". The applied security roles for WSNavigatorRole is most likly "administartors". Please change this to "all" if you want that everyone can at least call the wsnavigator application or restrict it by other criterias, BUT make sure your adsuser can access it! Change your changes

Now test the ADS RFC Connection from SM59. It should work now.
