We have a application with SharePoint 2013.
We have other external application with a users authentications (names, passwords, and other properties).
The external application its responsible to the user authentication at all system of company. Now we have to use this same application to manage the permissions of access at SharePoint 2013 site. In other words, we will not use the permission levels in sites, lists and libraries inside SharePoint, but we will use the assigned permissions at external service. The Administrator will set at the external system if a user has read permission ou colaboration at a determined site and when the user authenticate, the user will use that assigned access permissions.
Is it possible to break the default role permission of SharePoint and do this permission management using na API provides from the web servisse and/or using custom SharePoint Apps?
The same question: Can I control the permission level of users in a Team Site of SharePoint 2013 getting the permission level from a external system consulting a web service.
We are disposed to use FBA, NTLM but we need the control the permission outside SharePoint not the authentication method.
Thanks for any advice!
