{@link PropertyFileLoginModule} authenticates against a properties file.
The credentials should be stored in the format {username}={password} in the properties file.
The absolute path of the file needs to specified using the option <b>file</b>

<p><b>NOTE: This implementation is NOT intended to be used in production since the credentials are stored in PLAINTEXT in the
properties file.</b>
