I have mod_proxy configured on a FC8 box (httpd-2.2.8-1.fc8) and can't seem to get RPC/HTTP for Exchange working. I keep getting prompt for authentication. OWA is working (I had to disable Integrated Authentication on IIS). I'm not using SSL. Here is my settings in /etc/httpd/conf/httpd.conf:
NameVirtualHost *:80
<VirtualHost *:80>
ServerName webmail.dennischarley.com
SetEnv force-proxy-request-1.0 1
SetEnv proxy-nokeepalive 1
ProxyPass / http://webmail.domain.com/
ProxyPassReverse / http://webmail.domain.com/
</VirtualHost>
Thanks,
