<div>Do you intend to do a back channel query? If you don’t and it’s only happening on this box, that suggests attribute acceptance problems, so the error you observe would be incidental(that query would be expected to fail anyway).</div>
<div><br class="">
</div>
<div>If the query is intentional, then I’d start by trying to connect from the command line on the host with logging at a higher level. My suspicions would be intermediate network boxes that were munging the connection.</div>

<div class="gmail_default" style="font-family:garamond,serif">Would this be an issue because the version of the IDP server is a bit old? I see the latest release is: 2.4.3. (2014/11/03) and the version </div>

<div>This in particular, probably not. I would be fairly concerned about the security issues disclosed in earlier releases, though.</div>
