Authentication thru SAML

Hi All,

We are upgrading environment from version 7.0 to 7.8/7.10. Currently we are using the AD authentication for spotfire. However, we need to move to SAML authentication. 

One way I read was thru installtion of an example with Shibboleth. But this needs a seperate installation of the service provider. Is there any other way to do it?

Quick inputs appreciated.
