[xwiki-users] adding a custom jar / code

Hi all, I'm trying to extend the XWikiAuthServiceImpl as described here[1][2] to make use of local SSO. Here are the steps I'm following but xwiki will not startup.. Do I have somethings out of place in my steps? 1. Place my jar in ${XWIKI_HOME}/WEB-INF/lib jar named org.my.authenticator 2. Edit ${XWIKI_HOME/WEB-INF/xwiki.cfg inserting xwiki.authentication.authclass=org.my.authenticator.UserAuth 3. Start xwiki .. this fails! Do I have the jar in the correct place? Do I need to tell xwiki to enable the use of this "new" jar? My code does not do anything of importance right now.. It gets a Log object and writes one entry.
