AD FS deployment requires a few SSL certificates. In this demonstration, we will use the following:
- *.rebeladmin.com: This is a wildcard SSL certificate for external URLs. This is used for the application and WAP.
- rebeladmin.com: This SSL is for AD FS service communication.
In the lab environment, we can create these certificates using internal Certification Authority (CA). If the domain name is the same, then wildcard certificates are used internally and externally as well. Wildcard certificates simplify certificate management.
