         Hi Rüdiger/all
 
         Thanks for the reply 
 
         But is there any workaround available for using NTLM with MPM
worker or a way to turn off connection pooling.
         
         Regards

NTLM currently does not work with httpd 2.2.x and reverse proxy
configurations due to the fact that httpd 2.2.x
uses connection pooling for its backend connections. NTLM does not respect
the fact that HTTP is a stateless
protocol. Thus is fails.

Betreff: Repeated NTLM authentication boxes for OWA 2k3 with Reverse
Proxying Apache 2.2




Hi all 

I have made following setup with Apache 2.2 


Client <---https---> Apache 2.2.3 <--------> OWA 2k3 server 

in my conf I have 

Listen 172.25.12.146:80 
<VirtualHost 172.25.12.146:80> 
   DocumentRoot "/myroot/abc/" 
   ServerName application.owa.com 
        <IfDefine PROXY> 
          ProxyPass        / http://application.owa.com/
<http://application.owa.com/>  

        ProxyPassReverse / http://application.owa.com/
<http://application.owa.com/>  
        ProxyPassReverse / http://application.owa.com:80/
<http://application.owa.com:80/>  
        ProxyPassReverse / http://172.25.11.33/ <http://172.25.11.33/>  
        ProxyPassReverse / http://172.25.11.33:80/ <http://172.25.11.33:80/>

     </IfDefine> 
</VirtualHost> 



but when I try to connect I get repeated NTLM authentication boxes but OWA
resource is available after many attempts.If I click any other link on OWA
it again asks for NTLM authentication. 

Also the very same httpd.conf and network setup is working fine with Apache
2.0.53 hust replacing the httpd 

Is there any change in the two version regarding the same .... 

Or if anyone has experienced this .Please help......... 


Thanks/regards
