Hi all, i'am using apache2 v. 2.4.10 as reverse proxy. Everything works great except for last "location", inside a existent virtual host, i've added
Client side connect, after i gave username and password. It loads pages. Then, when i click on some buttons that redirects on desired feature, sometimes, not always, username and password's prompt appears again.
What is wrong? Why site ask me again credentials?

Here a snippet of code:

Code:
#------SERVICE-------#

<VirtualHost *:443>
    RewriteEngine on
ServerName name.domain.com

    ProxyRequests Off
    ProxyErrorOverride Off
    ProxyPreserveHost On
  #  ProxyReceiveBufferSize 4096
    KeepAlive On
    ProxyTimeout 1200
   

  <IfModule reqtimeout_module>
        RequestReadTimeout header=20-40,MinRate=500 body=20,MinRate=500
  </IfModule>

  SSLEngine on
  SSLProxyEngine on
  SSLProxyVerify none
  SSLProxyCheckPeerCN off
  SSLProxyCheckPeerExpire on
  SSLProtocol all -SSLv2 -SSLv3
  SSLCipherSuite ALL:!ADH:!EXPORT:!SSLv2:RC4+RSA:+HIGH:+MEDIUM:+LOW
  SSLCertificateFile /etc/apache2/certs/wildcard_lw.pem
  SSLCertificateKeyFile /etc/apache2/certs/wildcard_lw.key
  SSLCertificateChainFile /etc/apache2/certs/GoD-intermediate.crt

Hi James.
I resolved yesterday!!! Seems that APACHE does not work properly with NTLM Auth.
Infact i disabled it on IIS8 and enabled BASIC AUTH and now it work perfectly.

Can you confirm that APACHE has problems with NTLM Auth?
Thank you

I got only https://github.com/YvesR/mod_authn_ntlm/ to work. Which is a 3rd party module. Unless you have a big bunch of users who you manage over Windows auth basic is just fine.
