In a production situation, we recommend using the same SSL certificate for the WAP. Additionally, we strongly recommend using the same SSL certificate across all nodes of your AD FS farm as well as the WAPs in your AD FS farm. Wildcard and multi-name certificates will work, but it's best to keep things simple and use a standard SSL certificate in a production situation. Make sure that the common name matches the AD FS server farm name.
