Hi, Apache 2.0.53 with mod_proxy gets Requests from Clients, Requests are send to the Backendsystem. In one case, the User is authenticated by Apache using SSL Clientcertificate. In another case, users without clinetcertificate can use Basic Auth(mod_auth_ldap) for authentication. Authorisation is done completle in the Backendsystem. Apache writes an extra Header "USER_ID" when authentication is done. Value of this header is the username. The Header USER_ID is used by Backendsystem to authorize the User. Now the Problem: Working: RequestHeader set "USER_ID" %{SSL_CLIENT_S_DN_CN}e Not working: RequestHeader set "USER_ID" %{REMOTE_USER}e in this case, the Header USER_ID is set, but value is (null). The Apache ENV Var REMOTE_USER is filled correctly, bacuse i can see the right value in the Log. (RemUser: %{REMOTE_USER}x) So why the Header can't be filled with %{REMOTE_USER}e ?
