[xwiki-users] xwiki-authentication-headers

Hi list, I'm trying to use the XWikiHeadersAuthenticator from xwiki-contrib. I'm new to XWiki as you will see. I built it with maven and put the jar in /usr/lib/xwiki/WEB-INF/lib. Now I can see it in the core plugins : "xwiki-authentication-headers", "default install". I put XWiki behind an Apache reverse-proxy that set http headers, but nothing special happened. I put <logger name="org.xwiki" level="debug"/> in /usr/lib/xwiki/WEB-INF/classes/logback.xml, but I never see the "Headers auth started" banner that comes from this plugin's CheckAuth() Is there anything special to do to register it ? Docs refer to XAR plugins. So I added this in the pom.xml : <packaging>xar</packaging> <build> <extensions> <extension> <groupId>com.xwiki.authentication</groupId> <artifactId>xwiki-authentication-headers</artifactId> <version>1.0-SNAPSHOT</version> </extension> </extensions> </build> Now I've got a xwiki-authentication-headers.xar, but I don't know what to do with it. Any help will be greatly appreciated ! Thanks, Sam.
