You managed to sort this one? out? I have exactly the same problem. All works fine on JBoss 3.0.6 but when deployed in JBoss 3.2.2 Datasource and EJB's are fine but login fails with no error messages.
Hey, I could not manage to sorti this problem out yet,
yours is the only answer I got... :(
I'm still hoping to get somehow the right answer...
could you send me login-config.xml and <security-domain> tag fromyour jboss-web.xml ?
