IdPv3 jetty9 back-channel setup help needed

[Francesco Malvezzi]

Hi all,

Having tried it hard for a couple of days, I have to admit I am unable
to setup correctly a IdPv3 with jetty 9.2, java 1.8, Debian GNU/Linux.

The problem is attribute authority which always fails as if payload
would be empty:

2015-01-21 13:39:32,685 - ERROR

So client receives a fairly generic error:
<?xml version="1.0" encoding="UTF-8"?>
<soap11:Envelope
xmlns:soap11="http://schemas.xmlsoap.org/soap/envelope/"><soap11:Body><saml1p:Response

jetty-base is the jetty-base dir in the idp unzipped source.

In jetty-base I modified only a few properties about the back-channel
port, and about back-channel keystore (location, password and so like).

Naively, I suspect it's something connected to jetty9-dta-ssl-1.0.0.jar,
but I can't have any logline about: net.shibboleth.utilities.jetty9, nor
in shib logs, neither in jetty logs.

Whence should I start to pinpoint my error?

Do you need a log of the installing procedure? Or some of the
configuration files?

The attribute request client command (curl) does work if the target is
idpv2.

Thank you in advance for your time,

Francesco
