I am also using jBoss-4.2.1-GA and JBoss_Portal_2_6_1 Pretty sure I didn't miss anything...I went through it a couple of times. Here's what I did notice: * If I attempt to login with an id that is not in AD, I get the expected "Invalid user ID/Password" message. * If I attempt to login with an id that is in AD, I get the error message I posted. It appears that it is able to search LDAP and find users. It just seems like it does not like the shape of my LDAP entry that it finds, resulting in the error: Caused by: javax.security.auth.login.LoginException: org.jboss.portal.identity.IdentityException: Co | uldn't create LDAPUserImpl object from ldap entry (SearchResult) Is the code that builds the LDAPUser looking for specific fields in LDAP that I do not have? How do I know what is required? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4072584#...
