Hello, I change the flag of my CustomIdentityModule from "requisite" to "requred" in the login-config.xml file. | <login-module code = "org.login.CustomIdentityModule" flag="requred" | Unfortunately the behaviour that the SynchronizingLoginModule always invokes and synchronize remains, if the login() -Method of the CustomIdentityModule returns false. That should not be. I don't know what I can do anymore. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4146102#...
