// Note: For this to work, you'll likely need to update your .htaccess file on your WordPress server.
// Otherwise you'll get this error:
// 
// 401 : Sorry, you are not allowed to create posts as this user

// Your default .htaccess file probably looks like this:
// 
// <IfModule mod_rewrite.c>
// RewriteEngine On
// RewriteBase /
// RewriteRule ^index\.php$ - 
// RewriteCond %{REQUEST_FILENAME} !-f
// RewriteCond %{REQUEST_FILENAME} !-d
// RewriteRule . /index.php 
// </IfModule>
// # END WordPress
// 
// Add the following line immediately after the "RewriteEngine On" line:    RewriteRule .* - [E=REMOTE_USER:%{HTTP:Authorization}]
// Your .htaccess file should look like this after the edit:
// 
// <IfModule mod_rewrite.c>
// RewriteEngine On
// RewriteRule .* - [E=REMOTE_USER:%{HTTP:Authorization}]
