I have configured and installed shibboleth Idp and sp on a Ubuntu machine locally. The Idp is configured with LDAP.
I am trying to access the secure.html file which hosted in Apache and secured by shibboleth sp, So when I try to access the page it would redirect to Idp login page for authentication. When login with the correct username and password I get the following error message:
opensaml::FatalProfileException The system encountered an error at Wed Oct 15 18:54:04 2014 To report this problem, please contact the site administrator at root@localhost. Please include the following message in any email: opensaml::FatalProfileException at (https://idp.example.org:553/Shibboleth.sso/SAML2/POST) SAML response contained an error.

What can cause this error?
