MacBook Wireless Borked Again, Still, etc.

The way to do this is to add Subject Alternative Names (SAN) to the certificate. This enables you to access the website in different ways, e.g.;

  • Access a webmail host from the internet based on its official FQDN (
  • Access the same webmail host from the inside of the corporate lan based on its internal name (https://webmail.acme.local)
  • And access the host from legacy DNS-unaware software on its IP address (
