SAML 2.0 with Nginx and WordPress 4.4.2

After migrating from apache to nginx I had a fair bit of difficulty getting this plug-in to work using 4.4.2, nginx and php5-fpm.

Here is the configuration that I got to work.

Webserver configuration – /etc/nginx/sites-enabled/www.conf

server {
...
# add this line to include the file below
include /etc/nginx/global/simple-saml-php.conf;
}

/etc/nginx/global/simple-saml-php.conf

# this replaces the .htaccess file at wp-content/uploads/saml-20-single-
# sign-on/etc/certs called in /lib/classes/saml_settings.php @ line 320
# line 320 of gets commented out to avoid an error message.
location  ~ \.key$ {
   deny all;
}

# this allows the reply url to process properly
location /wp-content/plugins/saml-20-single-sign-on/saml/www/ {
  location ~ \.php(/|$) {
      fastcgi_split_path_info ^(.+?\.php)(/.+)$;
      fastcgi_param PATH_INFO $fastcgi_path_info;
      fastcgi_pass 127.0.0.1:9000;
      fastcgi_index index.php;
      include fastcgi_params;
      fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
  }
}
