Empty SAML Info (Windows IIS Host)

Have you checked the file path it mentions to see if the certificate file is there?

Well it actually looks like two paths concatenated together:

C:\inetpub\development\content\plugins\saml-20-single-sign-on\saml/cert/C:\inetpub\development/content/uploads/saml-20-single-sign-on/etc/certs/1/1.cer

The first of the paths is invalid, there is not a cert directory, instead it is certs.

The certificate and key exist at:

C:\inetpub\development\content\uploads\saml-20-single-sign-on\etc\certs\1

And are IIS readable.

Are you setting the custom content directory with a directive in wp-config.php? Would you mind sharing that line if so? it’s kind of an edge case, so I probably haven’t fully accounted for the way you’re using it.

Sure. Here’s the entry in the wp-config:

define( 'WP_CONTENT_DIR', $_SERVER['DOCUMENT_ROOT'] . '/content' );
define( 'WP_CONTENT_URL', 'https://'.DOMAIN_CURRENT_SITE.'/content');

Hey Aaron,

The problem you were having is from deep in the SimpleSAMLPHP Library, which has a function that assumes absolute paths will only ever begin with a forward slash. This is true for Linux, but not Windows.

I’ll patch this soon, but in the meantime, you could apply the patch yourself in /content/plugins/saml-20-single-sign-on/saml/lib/SimpleSAML/Utilities.php, line 1088 or so.

Replace the if/else structure you find in that function with this:

/* Check for absolute path. */
		if(substr($path, 0, 1) === '/') {
			/* Absolute path. */
			return $path;
		}
		/* Check for Windows absolute path. */
		elseif( preg_match('/([a-zA-Z]:|\\\\[a-zA-Z0-9])/', substr($path, 0, 3) ) ) {
			/* Either a a drive letter or Windows Share */
			return $path;
		}
		else {
			/* Path relative to base. */
			$ret = $base;
		}

I’ve just quickly tested this in an AWS instance I threw together today, so I would appreciate your feedback on whether this works for you or not.

For what it’s worth, I had exactly the same problem today with the missing SAML info. Replacing that line in the Utilities.php file does seem to have fixed it for me.
