I set up an apache http reverse proxy and load balance.

I already know that Reverse Proxying will break NTLM dialog, and leads to something like Basic Auth against Active Directory, which is sufficient for me.

NTLM is supported by jCIFS on my JBoss, and is working fine when:

  • I use my JBoss address directly (
  • I use my apache RP address ( without a 2nd member

But since adding second member to load balancing, it don't work at all !

<VirtualHost *:80>

  ServerAlias myapp-homintranet

  ProxyRequests Off
  ProxyPass /myapp balancer://jbosscluster/myapp stickysession=JSESSIONID nofailover=On
  ProxyPassReverse /myapp

  #Conf load-balancing Jboss
  <Proxy balancer://jbosscluster>
    ProxySet lbmethod=byrequests


If I remove the second member (server 02), it works again.

I don't know how to solve this. Can someone help me ?

PS : If there is a way to highlight apache/conf syntax, tell me !

My workers conf, in case ...

# Define list of workers that will be used
# for mapping requests

# Define Node1 = server01
# modify the host as your host IP or DNS name.

# Define Node2 = server02
# modify the host as your host IP or DNS name.

# Load-balancing behaviour

# Status worker for managing load balancer

I didn't find any real solution to this issue. We just changed our auth method (using Kerberos and mod_auth_kerb, which were painful to configure).

I think there was an issue between the virtual IP and the Windows realm. We also encountered this problem with Kerberos. But we have not tested it again.

I hope this will help someone.
