<span style="font-size:10.0pt;color:#002060">I am implementing an SP initiated web browser SAML 2.0 SSO profile.<br>
I am using Shibboleth IDP for testing.<br>
When I send an unsigned AuthenRequest everything works fine. The IDP excepts the request and logs me in.<br>
Now I am trying to add a signature to the AuthnRequest.<span class="apple-converted-space"> </span><br>
Surprisingly, it works fine in FireFox and Chrome, but when using IE I get an error page with message "</span><span style="font-size:10.0pt;color:#7030A0">Error decoding authentication request message</span><span style="font-size:10.0pt;color:#002060">".<br>
In the IDP log I see an error "</span><span style="font-size:10.0pt;color:#7030A0">Invalid XML</span><span style="font-size:10.0pt;color:#002060">" --> "</span><span style="font-size:10.0pt;color:#7030A0">Encountered error parsing message into its DOM representation</span><span style="font-size:10.0pt;color:#002060">".<br>
This error doesn't exist when using FF/Chrome.<br>
Do you have an idea what might be the cause for this behavior?<o:p></o:p></span></p>
