hi, the problem is : login module class must be in system class path. happy news is that you can use ProxyLoginModule instead of directly declaring your class. look at the config file : <login-module code="org.jboss.security.auth.spi.ProxyLoginModule" flag="required"> | <module-option name="moduleName">org.jboss.portal.core.identity.MyLoginModule</module-option> | <module-option name="unauthenticatedIdentity">guest</module-option> | <module-option name="userModuleJNDIName">java:/portal/UserModule</module-option> | <module-option name="roleModuleJNDIName">java:/portal/RoleModule</module-option> | <module-option name="userProfileModuleJNDIName">java:/portal/UserProfileModule</module-option> | <module-option name="membershipModuleJNDIName">java:/portal/MembershipModule</module-option> | <module-option name="additionalRole">Authenticated</module-option> | </login-module> for further : http://docs.jboss.org/jbossas/admindevel326/html/ch8.chapter.html best regards View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4171145#...
