•  Installation Guide updated to include instructions for configuring MyProxy as a SimpleCA and PAM interface to target site specific authentication system.

[pjkersha]

The documentation needs to be revised as recent changes mean that the installation process is simplified:

• a paster template can be used to create the configuration for a deployment instead of the need to use the ndg-security-install script or manual copying of files and directories.
• The Session Manager authentication plugin means that MyProxy is no longer a required component. Instructions for MyProxy installation can be moved to an Appendix.
