Thanks jaikiran! I solved my problems! But I wondered that: If I write my login-config.xml: <?xml version="1.0" encoding="UTF-8"?> | | <policy> | <application-policy name = "DB-Domain"> | <authentication> | <login-module code = "org.jboss.security.auth.spi.DatabaseServerLoginModule" | flag = "required"> | <module-option name = "unauthenticatedIdentity">guest</module-option> | <module-option name = "dsJndiName">java:/DefaultDS</module-option> | <module-option name = "principalsQuery">SELECT PASSWD FROM USERS WHERE USERID=?</module-option> | <module-option name = "rolesQuery">SELECT ROLEID, 'Roles' FROM ROLES WHERE USERID=?</module-option> | </login-module> | </authentication> | </application-policy> | </policy> When the authentication will fail! But if I use login-config.xml inside \server\default\conf and add some informations (above) the authentication success! Why ?( If I want myself write my login-config.xml) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4024553#...
