I bought a wildcard certificate on Azure for my projects * .mydomain.com. I need the certificate to work with my resources. Resources are of the form * .dev.mydomain.com * .stage.mydomain.com * .test.mydomain.com. As I understand it, I need to add a subject alternative name (SAN) to the certificate. How can i do this? Is it possible to add or change a SAN for a certificate on Azure?

    Hi @Anonymous ,

    Since your certificate is a wildcard, you don't need to use a SAN for each of your app services. If you're using Azure for DNS, all you need to do is add the CNAME records for your app service, validate, and then bind your wildcard cert to it. Bada-bing bada-boom. But do let me know if you have any issues with a comment below. Also, apologies for getting a response days after.
