Why not use the actual hostname?

It really has to do with CNAME or server aliases in /etc/hosts. Say one box is also known as '', '', '', '', etc... My understanding is the '*' CN prevents any potential conflict from a cert standpoint when SSL/TLS authentication is invoked from the different servers (ssh, sftp, saslauthd, https, etc...)

I've never really gotten a concise "why?" answer, but that is my best guestimate at the legitimate reason why...

Anybody else with more info on this, please chime in, I'm curious as well...
