If the certificate is being certified for free it's worth
about that much.
While I agree with most of what other people have said in this
thread, I don't think you can take the above as a blanket statement.
I buy SSL certificates for my public facing websites.
For everything else that is internal, chat, mail, web, ldap, I have
my own CA.
If you do this properly, and deploy your CA certificate as part of
your client image, then there's no need to go and buy certificates
for everything. Free self-signed certificates are worth more than
zero for internal purposes...
