使用ADFS配置SimpleSamlPhp的问题

Question

I'm having some difficulties to configure SimpleSamlPhp with ADFS.

Here is the procedure that I have followed:

SimpleSAML is installed and configured on my web server Apache (example.com) and ADFS2 is installed on your federation server (myadfs).

• Open a browser and go to URL https://myadfs/Federationmetadata/2007-06/FederationMetadata.xml
• Save as FederationMetadata.xml.
• Open a browser and go to https://example.com/simplesaml
• Select Federation tab
• Click on Convert XML Metadata to simpleSAML.php
• Paste the content of the previous file (FederationMetadata.xml)
• Click on Analyse
• On saml20-idp-remote section, select all text and copy it
• Edit the file <document_root>/simplesamlphp/metadata/saml20-idp-remote.php (save a copy like saml20-idp-remote.bak)
• Delete all text between <?php … ?> (keep the <?php and ?>)
• Paste the previous selected text between <?php and ?>
• Under entityid line, add following line: 'sign.logout' => TRUE,

• Save saml20-idp-remote.php

• Edit the file <document_root>/simplesamlphp/config/ authsources.php. In the $config array add an entry like

  'myauth' => array( 
      'saml:SP', 
      'idp' => 'http://www.myadfs.com/adfs/services/trust', 
      'privatekey' => '001-mysite.key', 
      'certificate' => '001-mysite.crt', 
  ), 
  

Then I sent my Metadata to my network administrator for him to authorize my connection.

Unfortunately when I try to connect I directly get the ADFS error without being able to input my credentials.

My Network Administrator told me that the error was the following:

The data at the root level is invalid. Line 1, position 1.

Apparently he cannot read the certificate on a windows server but we have successfully installed Wordpress SSO on Microsoft Azure using a plugin that use this exact same PHP Plugin and it has been working fine.

Does someone have any idea how to fix it? Thanks!
