All Implemented Interfaces:

LoginModule

public class SQLLoginModule
extends Object
implements LoginModule

A login module that loads security information from a SQL database. Expects to be run by a GenericSecurityRealm (doesn't work on its own).

This requires database connectivity information (either 1: a dataSourceName and optional dataSourceApplication or 2: a JDBC driver, URL, username, and password) and 2 SQL queries.

The userSelect query should return 2 values, the username and the password in that order. It should include one PreparedStatement parameter (a ?) which will be filled in with the username. In other words, the query should look like: SELECT user, password FROM credentials WHERE username=?

The groupSelect query should return 2 values, the username and the group name in that order (but it may return multiple rows, one per group). It should include one PreparedStatement parameter (a ?) which will be filled in with the username. In other words, the query should look like: SELECT user, role FROM user_roles WHERE username=?

This login module checks security credentials so the lifecycle methods must return true to indicate success or throw LoginException to indicate failure.
