Description

 Web Application Proxy provides reverse proxy functionality for web applications within a corporate network.Web Application Proxy (WAP) works in conjunction with Active Directory Federation Services (AD FS) which is an application developed by Microsoft that provides users with single sign-on access to systems and applications located across organizational boundaries. It uses a claims-based access-control authorization model to maintain application security and implement federation identity.

Prerequisites:

One or more certificates must be installed on the Web Application Proxy Server. 
1. A certificate must be installed on the WAP server for AD FS to utilize. See related articles for more information on the installation and configuration of Active Directory Federation Services (AD FS).
2. Certificate(s) must be installed on the WAP server for all published URLs when SSL is to be used.
3. The Web Application Proxy server (WAP) must be configured to act as a Delegate for backend servers that will use AD FS as it pre-authentication method.
 -  Active Directory Users and Computers 
 - Web Application Proxy computer object (properties) 
 - Delegation tab
 - Add backend server with Service Type (HTTP) and choose 'Trust this computer for delegation to specified services only - Use any authentication protocol'
