Jetty LdapLoginModule: Login Failure: all modules ignored

问题

I'm getting the below on trying to submit a login form. Does anyone know what causes this? Thanks.

FWIW this is some of the peripheral configuration:

jetty.xml:

<?xml version="1.0"?>
<Configure>
    <Call name="addBean">
        <Arg>
            <New class="org.eclipse.jetty.plus.jaas.JAASLoginService">

                <Set name="loginModuleName">ldaploginmodule</Set>
            </New>
        </Arg>
    </Call>
</Configure>
