Hi, I?m trying to install reverse proxy with Apache. But ldap authentication doen?t seem to work. When I directly access to the internal website (web.newdomain.com) : no problem, I have an authentication popup. When I access via reverse proxy, there is no authentication popup and it doesn?t work. I don?t understand why I don?t have authentication popup with reverse proxy. I can see to logs the ?GET /? in both situations? Someone can help me ?
