Question

Please help me out for the below mentioned scenario….

applicationContext-security.xml

<authentication-manager>
  <authentication-provider>
     <jdbc-user-service data-source-ref="dataSource"
         users-by-username-query="SELECT username, password FROM myLibrary.user WHERE username=?" />
  </authentication-provider>
</authentication-manager>

database-end(MySQL)

CREATE TABLE `myLibrary`.`user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
    `enabled` bit(1) DEFAULT NULL,
  `fullName` varchar(255) DEFAULT NULL,
  `password` varchar(120) DEFAULT NULL,
  `username` varchar(40) NOT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `id` (`id`),
  UNIQUE KEY `username` (`username`)
);

xml-user

<user-service>
    <user name="admin" password="amdin" authorities="supervisor, user" />
    <user name="counter1" password="counter1" authorities="user" /> 
</user-service>

“dataSource”; values as perfect too…!!! And there is no exception in any logs….which means library integration is perfect. In fact while using XML based user definitions it works great….but in database access it falis.

My login page sticks to the same; i mean login fails. Pls help friends….!!!!

Sorry for the delay….!!! so the problem is at the table responsible for users and that must have to be users. And it’s running awesome…..!!! thanks friends…..thanks a lot…!!!!

<authentication-manager>   <authentication-provider>      <jdbc-user-service data-source-ref="dataSource"/>   </authentication-provider> </authentication-manager>

Before the above xml-lines; make sure the table for the users must have to be users and also another table authorities must exists with foreign key to users - username. Ok..allow me to put the database part too..!!

CREATE TABLE `myLibrary`.`users` (     `id` int(11) NOT NULL AUTO_INCREMENT,       `enabled` bit(1) DEFAULT NULL,     `fullName` varchar(255) DEFAULT NULL,     `password` varchar(120) DEFAULT NULL,     `username` varchar(40) NOT NULL,     PRIMARY KEY (`id`),     UNIQUE KEY `id` (`id`),     UNIQUE KEY `username` (`username`)   );

CREATE TABLE `myLibrary`.`authorities` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `authority` varchar(255) NOT NULL,
  `username` varchar(255) NOT NULL,
  `allowed` bit(1) DEFAULT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `id` (`id`),
  KEY `fk_username` (`username`),
  CONSTRAINT `fk_username` FOREIGN KEY (`username`) REFERENCES `users` (`username`) ON DELETE NO ACTION ON UPDATE NO ACTION
) ;

Please note that; authorities(allowed) is not mandatory….it’s part of my code..as i want to show the user….all of it’s authorities regardless of it’s permission to use.

I am using hibernate and so i am getting ID field…and off-course it’s upto you as fas as it’s usability is concerned.

Have a nice day…!!!!
