LDAPS

Hi hackers,

I've run into a few requests for $SUBJECT in the field.  I understand
that this is a bit controversial: LDAP + StartTLS (what we already
support) is better than LDAPS because it's a proper standard, and LDAP
auth in general is not as good as some other authentication methods
that we should be encouraging.  I don't actually have a strong view on
whether we should support it myself, but I took a swing at it to see
if there would be any technical obstacles.  I did not find any.  That
said, I've only tested the attached lightly on FreeBSD + OpenLDAP and
don't know if it'll work elsewhere.  Thoughts?
