This is the part 3 of the series of articles which explains about the AD FS and configuration. If you still not read the part 1 and 2 you can find it here.
In this post let’s see how we can install AD FS web application proxy. As I explain on part 1 of the series, web application proxy need to be installed in perimeter network. Using it we can authenticate AD FS users before allow access to published application in corporate network.
Installation of Web Application Proxy
External DNS record
To access the web service from external it needs valid external DNS record which can use to connect from internet. If your organization DNS hosted in external make sure you create appropriate records and allow time for DNS propagation before proceed with the installation.
In here for the demo I have created DNS entry for host name adfsproxy.contoso.com and point it to the server which will use for the service install.
To allow the HTTPS communication it is must to have valid SSL certificate in place to use with the proxy server. It can be from external SSL provider or via company CA. it needs to match with the DNS entry we created on previous step.
In demo I have created self-signed SSL and deploy it on the server.
To start the installation, log in to the server you choose as domain admin or enterprise admin.
1) Load Server Manager > Add Roles and Features
2) It will open up the add roles and features wizard. Click next to continue.
3) In next window keep selection as “Role-based or feature-based installation” and click next to continue.
