<p class="MsoNormal"><span style="font-size:11.0pt">Hello,<br>
<br>
I upgraded a machine with a very old Debian OS version to a newer, but<br>
still old Debian version, thereby going from shibboleth 2.6.0 to 3.0.4.<br>
Unfortunately, though shibd starts with the old configuration file, the<br>
apache does not work like expected anymore, but the corresponding web<br>
page shows in the browser:<br>
<br>
Unknown or Unusable Identity Provider<br>
<br>
The identity provider supplying your login credentials is not<br>
authorized for use with this service or does not support the necessary<br>
capabilities.<br>
<br>
To report this problem, please contact the site administrator at<br>
root@localhost.<br>
<br>
Please include the following error message in any email:<br>
<br>
Identity provider lookup failed at<br>
(<a href="https://example.tu-dortmund.de/otrs/index.pl/index.pl">https://example.tu-dortmund.de/otrs/index.pl/index.pl</a>)<br>
<br>
EntityID: <a href="https://idp.example.org/idp/shibboleth">https://idp.example.org/idp/shibboleth</a><br>
<br>
opensaml::saml2md::MetadataException: Unable to locate metadata for<br>
identity provider (<a href="https://idp.example.org/idp/shibboleth">https://idp.example.org/idp/shibboleth</a>)<br>
<br>
Please help. I attached the configuration file (with DNS names<br>
replaced), I hope that it helps to understand how the whole thing<br>
should work ..<br>
<br>
Regards<br>
Christoph <o:p></o:p></span></p>
