I am running two simplesamplephp instances (one for SP and one for IdP) and playing around with SSO. My IdP uses openLDAP for authorization.
I started from the following php code by putting them in an example.php file, put the example.php file in apache httpd and visit it from browser:
$as = new SimpleSAML_Auth_Simple('example-sp');
$as->requireAuth();
$attr = $as->getAttributes();
print ………..
It appears that the authentication request was able to be sent from sp to Idp and here is the sp log:
Jul 06 19:56:06 simplesamlphp DEBUG [a08a5cff76] Session: 'example-sp' not valid because we are not authenticated.

Then in the Idp log I see the following (appears that IdP was able to receive the request):
Jul 06 19:56:06 simplesamlphp INFO [37f32bab7b] SAML2.0 - IdP.SSOService: Accessing SAML 2.0 IdP endpoint SSOService

Then in the sp log I see the following:

But in my browser I got the following error:

It may be down for maintenance or configured incorrectly.
Note 1 - I am not sure why in the sp log it said "Session: 'example-sp' not valid because we are not authenticated". Maybe at that point the security context hasn't been established yet and that 's exactly why we need to execute $as->requireAuth() for?
Note 2 - What does the error in browser indicate? Does it mean I have to set up some additional html file or form to enter user name / password for LDAP validation? Any clues on how to set things up?
Note 3 - I followed most of the config changes according to the simplesamlphp SP and IdP guides except that I didn't change the 'certFingerprint' value. Will that possibly be the issue? I have copies of goDaddy.com signed SSLs for my IdP and SP - should I use them?
I actually expects SSOService.php to direct sp to loginuserpass.php but not sure why it didn't. I am thinking I may miss a setup somewhere but not sure exactly where...
thanks!
