Mohamed,
You need to install the SP software on the app you want to create SSO with, then you can use the Gluu GUI to configure SSO and release attributes from your IDP.
Please see the documentation: [http://www.gluu.org/docs/admin-guide/saml/saml-sp-configuration/#install-shibolleth-sp-package](http://www.gluu.org/docs/admin-guide/saml/saml-sp-configuration/#install-shibolleth-sp-package)
Thanks.
