[HR][/HR] Hello. Apache2.2.22/Tomcat6 on Centos 5.5. I authenticate users in Apache using kerberos. In tomcat I can recover user using next configuration in Apache: ... AuthType Kerberos AuthName Autenticacion require valid-user RewriteEngine On RewriteRule .* - [E=RU:%{REMOTE_USER}] RequestHeader set X_REMOTE_USER %{RU}e But I'd like to send username as parameter: Ex: If receive /application/login.jsp Apache will rewrite the query and send Tomcat: /application/login.jsp?user=username I've tried with rewrite: <IfModule mod_rewrite.c> RewriteEngine On RewriteRule ^/application/login\.jsp$ /application/login.jsp?user1=%{REMOTE_USER}&host=%{REMOTE_HOST}&ident=%{REMOTE_IDENT}&user2=%{RU}e [PT] </IfModule> I receive host with the remote host, but the other parameters are empty. I've alto tried to include the rule below the kerberos section, but it doesn't work Whats wrong in the rule? Thanks
