Missing configuration file in SimpleSAML\Error\CriticalConfigurationError::fromException()

[ljt...@gmail.com]

What are you trying to do?

I'm trying to upgrade to v1.15.4.

What have you done?

Describe here the steps you have taken:

• What does your setup look like (e.g. number of servers, virtual hosts and/or domains; load balancers / TLS offloaders; version(s) of SimpleSAMLphp installed; how you configured SimpleSAMLphp --IdP? SP? proxy?; what other software are you using; etc)?
• At this point, I'm running it locally on my MacOS High Serierra
• What documentation are you following if you are following any apart from the official?
• I'm using composer require simpelsamlphp/simplesamlphp
• However, my current setting was:
• The config, metadata, and cert folders are inside the drupalsites/simplesamlphp folder.
• The simplesamlphp is installed is inside the vendor/simplesamlphp folder and created symlinks to ../simplesamlphp/config, ../simplesamlphp/cert, ../simplesamlphp/metadata
• However, my new version installation file structure are:
• composer require simplesamlphp/simplesamlphp
• created symlinks to ../../simplesamlphp/config, ../../simplesamlphp/cert, ../../simplesamlphp/metadata
• Are you using any third-party software (e.g. a Drupal plugin)?
• I'm running drupal 8
• How are you testing your setup?
• I tried accessing the site https://www.dd:8443 works but...
• I tried to go into https://www.dd:8443/simplesaml/ then it errors out
• Fatal error: Cannot redeclare ah_db_current_host() (previously declared in /Users/charlie/Sites/drupalsites/simplesamlphp/config/config.php:942) in /Users/charlie/Sites/drupalsites/simplesamlphp/config/config.php on line 942
  
• Line 942 refers to this function:

• function ah_db_current_host($db_cluster_id) {
      require_once("/usr/share/php/Net/DNS2_wrapper.php");
      try {
          $resolver = new Net_DNS2_Resolver(array('nameservers' => array('127.0.0.1', 'dns-master')));
          $response = $resolver->query("cluster-{$db_cluster_id}.mysql", 'CNAME');
          $cached_id = $response->answer[0]->cname;
      }
      catch (Net_DNS2_Exception $e) {
          $cached_id = "";
      }
      return $cached_id;
  }

• What did you do to debug your problem?
• I typed: drush ws --uri=site1 and it shows the error:

• 120932  05/Mar 10:28  php       error     SimpleSAML\Error\CriticalConfigurationError: The configuration (config/config.php) is invalid: Missing configuration file in SimpleSAML\Error\CriticalConfigurationError::fromException()

• etc

Any help is much appreciated.

Note that you are the administrator, noone else has any use for a
"tracking number" specific to your server.

That seems pretty clear to me. Either config.php is missing or other
config file it depends on?

I got rid of the previous error...now, I got this error the HTTP ERROR 500 when loading mysite.mainsite.com/simplesaml. In the log it showed:

There is no such thing (ah_db_current_host) in the default config.php:
https://github.com/simplesamlphp/simplesamlphp/blob/master/config-templates/config.php
so you must have added that.

I'm following these two documentation.

https://docs.acquia.com/articles/using-simplesamlphp-acquia-cloud-site#configure

https://www.chapterthree.com/blog/how-to-configure-simplesamlphp-for-drupal-8-on-acquia

We're using Acquia's cloud for hosting. The same config works fine with previous version v1.14.17. All I did was composer require simplesamlphp/simplesamlphp but I had to remove drupal/simplesamlphp_auth and require simplesamlphp/simplesamlphp first and then add drupal/simpesamlphp_auth back.

[Chong Lor]

Looks like the issue comes from the Acquia snippet, https://gist.github.com/acquialibrary/8059715. If I commented out this whole snippet, I'm able to load the https://example.prod.acquia-sites.com/simplesaml page. I just can't the default-sp authentication sources yet.

I'm getting this error now.

[ljt...@gmail.com]

This is block of code that SimpleSAML_Error is complaining about.

function SimpleSAML_exception_handler($exception)
{
    SimpleSAML\Module::callHooks('exception_handler', $exception);

    if ($exception instanceof SimpleSAML_Error_Error) {
        $exception->show();
    } elseif ($exception instanceof Exception) {
        $e = new SimpleSAML_Error_Error('UNHANDLEDEXCEPTION', $exception);
        $e->show();
    } else {
        if (class_exists('Error') && $exception instanceof Error) {
            $code = $exception->getCode();
            $errno = ($code > 0) ? $code : E_ERROR;
            $errstr = $exception->getMessage();
            $errfile = $exception->getFile();
            $errline = $exception->getLine();
            SimpleSAML_error_handler($errno, $errstr, $errfile, $errline);
        }
    }
}

I don't see any abnormal about this block of code. Any suggestion is appreciated.

[ljt...@gmail.com]

I put a die("Exception: ".$exception); after the SimpleSAML\Module::callHooks('exception_handler', $exception); line and it shows the following:

Hi Chong, 

Have you got any luck of this?

I got the exact same error as you got.

Any suggestion is appreciated.

Might this help?

Copy the default "config.php" file from "config-templates" into the "config" folder.

This got rid of the missing config file for me.

[Tsegaselassie Tadesse]

If you're using Apache check your Virtual Host configuration. Make sure the SetEnv SIMPLESAMLPHP_CONFIG_DIR is pointed to the exact folder where your config.php file is.

I had a similar issue just now and the above fixed it for me.

[Tim van Dijen]

Hi Chong,

You should check your ' saml:NameIDPolicy' in the default-sp authsource.. It's probably a string, where at some point we started requiring an array.

See Parameters:  https://simplesamlphp.org/docs/stable/saml:sp

Also note that 1.15.4 is extremely old and has several know security issues.. Please be adviced to use the latest stable (v1.18.7)
