# @mainpage  SSP Cloud Auth module for OpenNebula Sunstone

#

# @section desc Description

# This is a new authentication module for OpenNebula Sunstone. In its name SSP means 

# Simple SAML PHP (http://simplesamlphp.org/).

# SSP Cloud Auth module is useful, when a SingleSignOn is login needed, which service is realised 

# with SimpleSAMLphp. In this case, login handled by SimpleSAMLphp and so the Sunstone 

# auth module (this one) makes only the identification of the users. \n

# If new user wants to login, this module creates a new account for the user.

# 

# @section conf Configuration

# Configuration file is at the end of the main Sunstone configuration file (sunstone-server.conf).
