You might have misconstrued about Wildcard SSL functionality. Let me elaborate below in depth, Wildcard SSL certificate works on asterisk (*). You can assume of any sub domain in the place of asterisk.

Example 1: If you have issued SSL certificate *.domain.com, it will secure,

https://domain.com
https://www.domain.com
https://mail.domain.com
https://video.domain.com
https://anything.domain.com

But it won’t secure second level sub-domain.

Example 2: Now if you have issued cert on *.sub.domain.com, it will secure,

https://sub.domain.com
https://mail.sub.domain.com
https://photo.sub.domain.com
https://anything.sub.domain.com

Wildcard SSL issued on *.sub.domain.com will not secure any URLs under Example 1.

Now if you want to secure all the above URLs (Example 1 + 2), than you should go with Multi Domain Wildcard certificate. It will give you a facility to protect multiple level sub-domains with single certificate.

Discussing about Wildcard SSL Certificate in details.

The main function of Wildcard SSL is to secure website and its unlimited number of sub-domains.

But there are some limitation, you can only secure Level-1 Wildcard domains.

For Example if your Wildcard SSL certificate is for *.domain-name.com, you are allowed to secure Lelve-1 sub-domains as

  • blog.domain-name.com
  • login.domain-name.com
  • anything.domain-name.com

Now What if you wish to secure the sub-domain of a particular sub-domain? - This is your case.

And here, the Wildcard SSL for *.domain-name.com will not work. The ultimate solution is, you need to but Wildcard SSL Certificate for that particular sub-domain. This is called Second Level sub-domain security.

So if you wish to secure 2nd Level sub-domains of blog.domain-name.com, you need to purchase wildcard SSL certificate for *.blog.domian-name.com. Now you are allowed to secure following type of sub-domains as..

  • user1.blog.domain-name.com
  • user2.blog.domain-name.com
  • user3.blog.domain-name.com
  • user4.blog.domain-name.com

A wildcard certificate for *.domain.com (first domain sub domain) is not valid for www.sub.domain.com (second level sub domain). You will need a wilcard certificate for *.sub.domain.com.
