[xwiki-devs] anonymous user / custom authentication

Hi devs, In writing my own auth plugin I want the ability to run XWiki in anonymous browsing mode as well as the login request triggering my particular auth jar (much like xwiki.org - you can many pages w/out actually authenticating). I have two resulting questions. 1) Is there a magic user name in the form of XWiki."anonymous"/Guest etc.. that I can return in my checkAuth? OR am I thinking about this incorrectly and xwiki already knows that this user is who the context is representing.. 2) I see in reading the xwiki.cfg and tutuorials on how to run your own authentication code that there is a way to override the login page within the config. Is there also a way to "override" the call to the login? I know in (cough,cough) confluence they have a seraph mechanism that you can override what the login action is... looking for something similar here.. I've thought of perhaps using an apache rewrite rule on the login/XWikiLogin page to trigger my auth Thanks guys.. ------ thanks kevin.foote
