Well I managed to make some progress by writing a custom 'TomCat Value'. The Tomcat Value (which extends ValueBase) successfully set's the 'request's' Principal to the desired user (the Portal shows the messgage 'Logged in as : xxxxxxx') ! However, I'm logging in as 'admin' (curretly hardcoded in the custom Value class) and am setting all the roles of the user to 'Admin','User' and 'Authenticated'. But I can't access the 'Dashboard'. It's thorwing up a '403' - Access Denied error. Not sure where to go from here ! Thanks for info ! Groove View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4115542#...
