[cisco-voip] Field Notice from Cisco making Secure LDAP mandatory

[Anthony Holloway]

Well, slap my ass and call me Sally.  I change an existing secure LDAP
setup from FQDN to IP Address and it still works.

I'd be curious to know why it functions this way.  Seems like an
opportunity to exploit the Authentication facet of SSL.

*"In addition to encryption, a proper SSL certificate also provides
authentication. This means you can be sure that you are sending information
to the right server and not to an imposter trying to steal your
information."*
