Carbon Black App Control (formerly Cb Protection)


  • After completing authentication with the Identity Provider (IdP) an HTTP Error 500 is encountered on the URL:
  • Errors in the PHPErrors log similar to:
    PHP Fatal error:  Uncaught Error: Class "SimpleSAML\Error\Assertion" not found in C:\Program Files (x86)\Bit9\Parity Console\WebUI\simplesamlphp\www\_include.php:7
    Stack trace:
    #0 C:\Program Files (x86)\Bit9\Parity Console\WebUI\simplesamlphp\www\module.php(8): require_once()
    #1 {main}
      thrown in C:\Program Files (x86)\Bit9\Parity Console\WebUI\simplesamlphp\www\_include.php on line 7


  • App Control Server: 8.10.2
  • SAML Integration


This issue was tracked and investigated under EA-24309.


This issue was addressed with the release of Server 8.10.4 (EP-20492).

Additional Information

Previously the workaround to restore SAML was:
  1. Log in to the application server hosting the Console as the Carbon Black Service Account.
  2. Use an administrative command prompt to issue the following two commands:
    C:\WINDOWS\sysWOW64\inetsrv\appcmd.exe delete vdir /"Parity Console Web"/"SimpleSAML"
    C:\WINDOWS\sysWOW64\inetsrv\appcmd.exe add vdir /"Parity Console Web/" /path:/SimpleSAML /physicalPath:"C:\Program Files (x86)\Bit9\Parity Console\WebUI\simplesamlphp\public"
