Hi all, I'm really trying to do something that allows my users w/ assigned
roles to login w/ passwd through a servlet using the databaseServerLoginModule,
but having a hard time understanding what to do w/ so little documentation.
Here's what I've done so far and if someone could point me in the right
direction w/ more steps, much appreciated.
I've created tables in my postgresql database as such ...
| CREATE SEQUENCE principals_seq;
| CREATE TABLE Principals(
| principalId INT PRIMARY KEY,
| principalName VARCHAR(64)
| password VARCHAR(32)
| );
|
| CREATE SEQUENCE roles_seq;
| CREATE TABLE Roles(
| roleId INT PRIMARY KEY,
| roleName VARCHAR(32),
| roleGroup VARCHAR(32)
| );
|
And I have a ~/WEB-INF/login-config.xml file like this ...
| <application-policy name="myAppName">
| <authentication>
| <login-module
| code="org.jboss.security.auth.spi.DatabaseServerLoginModule"
| flag="required">
| <module-option name="unauthenticatedIdentity">
| guest
| </module-option>
| <module-option name="dsJndiName">
| java:/PostgresDS
| </module-option>
| <module-option name="principalsQuery">
| SELECT password FROM Users WHERE principalId=?
| </module-option>
| <module-option name="rolesQuery">
| SELECT roleId,'Roles' FROM Roles WHERE userId=?
| </module-option>
| </login-module>
| </authentication>
| </application-policy>
|
I'm not sure about how to use callbacks within a servlet but I think I'm
supposed to do this in my apps MVC controller. I made a LoginController, but as
you can see, I don't really understand the details here yet.
| CallbackHandler handler = new MyHandler();
| LoginContext lc = new LoginContext("some-config", handler);
|
| try {
| lc.login();
| Subject subject = lc.getSubject();
| }
| catch (LoginException le) {
| System.out.println("authentication failed");
| e.printStackTrace();
| }
|
Any more details here? Any help much appreciated.
