Configure DB Login Module in JBoss

Configure DB Login Module in JBoss

Add to conf/login-config.xml:

  • <application-policy name=”MyPolicy”>
  • <authentication>
  • <login-module flag=”required” code=”org.jboss.security.auth.spi.DatabaseServerLoginModule”>
  • <module-option name=”dsJndiName”>java:/AuthorityDB</module-option>
  • <module-option name=”principalsQuery”>SELECT Password FROM Users WHERE Username=?</module-option>
  • <module-option name=”rolesQuery”>SELECT Rolename, “Roles” FROM Roles WHERE Username=?</module-option>
  • </login-module>
  • </authentication>
  • </application-policy>

Application policy name declares a new policy. We will reference this name in each [web] application that wishes to use it.

The required flag means that the login module is required to succeed.

If it succeeds or fails, authentication still continues to proceed down the LoginModule list

Other options are: requisite, sufficient, and optional

Module option dsJndiName:
