Thanks for Peter so much. (most of my question are answered by you, thank you) Actually, I want to config the LDAP authentication. However, I get failure and it is hard to trace what's wrong. Do you have more example about LDAP Auth config? Or how to trace this auth error? At the original design of our LDAP server, no role is designed; not for this purpose. Therefore, I just want to skip this role checking in LDAP auth. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4232923#...
