Hi there,

I'm investigating the possibilities of building a company intranet on an external Linux/Apache server (LAMP stack). I'd like to be able to restrict access to just internal company computers (and with no explicit login required).

All internal traffic goes through a proxy server, but it is an external third-party proxy which is also used by countless other corporate clients throughout the world.

Should I be looking at htaccess black-magic, or is it best to authenticate against our Active Directory at the application level (php), using something like LDAP? Are there any other options? Is it even possible to use LDAP across an externally hosted application?
