How I can I access login information (including password) sent from an EJB client using a custom login module?

Issue

• I have a custom LoginModule within I would like to access the password from an ejb client. Unfortunately I didn't manage to access the orignal password provided from the ejb client. I only get an instance of org.jboss.as.security.remoting.RemotingConnectionCredential or a string containing the class name.

• What is the correct way to access the password (clear text) so that it's sent to the custom LoginModule?

• Our custom EJB security domain in standalone.xml is:

                <security-domain name="custom-ejb-domain" cache-type="default">
                    <authentication>
                        <login-module code="Remoting" flag="optional">
                            <module-option name="password-stacking" value="useFirstPass"/>
                        </login-module>
                        <login-module name="OneCustomLoginModule" code="com.case.loginmodule.OneCustomLoginModule" flag="sufficient" module="ejbcustom"/>
                        <login-module name="EJBCustomAuthenticatorLoginModule" code="com.case.loginmodule.EJBCustomAuthenticatorLoginModule" flag="sufficient" module="ejbcustom"/>
                    </authentication>
                </security-domain>
