Assume that I am having several domain names ( *.domain1.com, *.domain2.com and *.domain2.com). All these wildcard domains pointing single web application and site can access through multiple subdomains. Eg: sub1.domain1.com, sub2.domain2.com, sub1.domain2.com).
Question: Now we need to protect these domains through SSL. So Can I use single SAN certificates to protect all those wildcard domains? (Instead of buying separate wildcard SSL for each domain)
EG: Single SAN certificate for *.domain1.com, *.domain2.com and *.domain2.com and serve to https://<any subdomain>.domain1.com, https://<any subdomain>.domain2.com, etc..
Hi @pubudu28, thanks for posting.
When using a UCC (SAN) SSL certificate, you cannot include wildcards. You can only specify distinct FQDNs. If you want to secure multiple wildcards across multiple domains, you would need to use multiple wildcard SSLs.
