and I put the proxy:


ProxyPass /SG/ http://192.168.1.36:8088/SG/ retry=30
ProxyPassReverse /SG/ http://192.168.1.36:8088/SG/

the problem is that when I connect I error on the browser:

The system encountered an error at Fri Jan 9 15:24:07 2015

To report this problem, please contact the site administrator at
root at localhost.

Please include the following message in any email:

opensaml::BindingException at (
http://integration.services.net/SG/Shibboleth.sso/SAML2/POST)

Invalid HTTP method (GET).
