Yes, they validate an asuid. subdomain as a TXT record. Also asuid.www. assuming you are also using the www. subdomin on your website. I always have a primary domain redirect on my applications if they only need to serve a single primary domain. Possibly I could see this being an issue if you are creating subdomains per-tenant, or something of that nature. Maybe I'm not understanding the issue correctly, but I've always had to validate my DNS records with Azure before I could assign a domain name to a resource such as an App Service.
