TLS CA cert verification support

[Ken Coar]

Is adding more support for certificate processing in the roadmap?

I have a requirement to verify the CA cert that signed the LDAP server's
cert, but that granularity doesn't appear to have been reached yet.

Someone roughed out an initial pass
at https://gist.github.com/mintuhouse/9931865 but I don't know how it would
fit into the upstream code.

I'm looking for something like Python's

ldap.set_option(ldap.OPT_X_TLS_CACERTFILE,'/etc/pki/tls/certs/cacert.crt')

Thanks!

I see now that someone has already submitted a pull request for this as
issue # 87 https://github.com/ruby-ldap/ruby-net-ldap/pull/87

I haven't tested that, but I hope someone in the net-ldap project can vet
it and merge it..

Thanks!
