[ZendTo] LDAP authentication

Ken,

The UseSSL setting was for running it on a different port.
It turns out the ldaps://server_ip_address option (should use port 636 
by default) is better. And as it's a ldap*s* URL, it will use SSL/TLS 
anyway.
So you can safely leave authLDAPUseSSL set to false. It's over-ridden by 
the use of an ldaps URL.

Cheers,
Jules.
