net.shibboleth.idp.authn logging

You're not sending any categories that exist to that appender.

> <logger name="net.shibboleth.idp.authn"
> level="${idp.loglevel.idp.authn:-INFO}"/>

That's your logger, no appender included (so it goes to the default/parent category's appender).

> <logger name="Shibboleth-Authn" level="ALL">
>      <appender-ref ref="${idp.authn.appender:-IDP_AUTHN}"/>
> </logger>

And that part is meaningless, because there is no such category.
