[Zope] Best way to integrate Apache and Zope authentication realms?

[Tony McDonald]

Hi,
I have almost all my stuff in Zope, but we have a large package written in
PHP that I need to integrate into our Zope system. Our stuff is frontended
with Apache using the excellent VHM and some RewriteRules.

I authenticate in Zope using UserDB against a MySQL database.
The authentication in the PHP package is against MySQL too.

Anyone know how can I get people to authenticate using the Zope interface
(ie nice login box in the page) and be able to pass the authentication
information to this PHP subsystem?

I've got complete control over the realms used, the Zope server, the PHP
code (ah, the power!).

TIA
Tone.
