dubble authentication + reverse proxy + apache + owa 2003

[nootgevallen]

Hi ,

I've setup up a reverse proxy with apache 2 to my exchange 2003 server (OWA) . This works fine!
BUT...

I want a extra authentication before they get authenticated to my active directory.

I Implemented a authentication but that only works with a username and password that has the same user and password on active directory. I don't want that.

has anybody a solution that it doesn't has to be the same username and password as active directory??

thanx

the authentication in my httpd.conf :

AuthType Basic
AuthName "Fill in your Username and password"
AuthUserFile /etc/httpd/.htpasswd
require valid-user
AllowOverride None

Order deny,allow
Deny from all
Allow from all
