I have a problem which I think might be a bug. I have setup Apache as a Reverse proxy and it works fine! The backend Web server is IIS. For some of the web pages a user has to enter their Windows credentials to reach the web page. This also works fine! The Problem: What is required is first a general authentication so that one can reach the backend server, which means that one authenticates first at the proxy and then a second time to access the protected IIS web pages. The first authenticate to grant access through the proxy works fine, but the IIS authentication part doesn't. If I look at the error log Apache is trying to authenticate the user instead of passing it through. Why? Is there a simple answer? The relevant configuration: <VirtualHost *:443> ServerAdmin webmaster@localhost ServerName proxy.xxxxxx.com SSLEngine On SSLProxyEngine on SSLCertificateFile /etc/ssl/xxxxxxCA/www-cert.pem SSLCertificateKeyFile /etc/ssl/xxxxxCA/www-key.pem ProxyRequests Off <Location /> AuthType Basic AuthAuthoritative Off AuthName "Restricted Area - PharmaPart only" AuthLDAPAuthoritative Off AuthLDAPURL ldap://ldap.xxxxx.net/ou=people,dc=xxxxxx,dc=com?mail?sub?(objectClass=*) Require valid-user ProxyPass http://ppzhsr02.xxxxxxx.net/ ProxyPassReverse http://ppzhsr02.xxxxxx.net/ </Location> <Proxy *> Order deny,allow Allow from all </Proxy> Like I've stated - take the Authxxxx part away and the IIS authentication works fine. It appears to me that when I put the Authxxxx statements in place that the Proxy wants to do all authentications rather than just the first access authentication. Can anyone help?
