The backend extension that provides SAML as authentication mechanism is introduced via optional packages:
* A virtual package open-xchange-saml which depends on two other packages open-xchange-saml-core and open-xchange-saml-backend.
* open-xchange-saml-core is provided by Open-Xchange as a binary package and contains a new bundle com.openexchange.saml. It
provides the general support for SAML authentication.
* open-xchange-saml-backend is environment-specific and needs to be provided by the operating party.

To use SAML in production, extensive configuration as well as development efforts are needed. An comprehensive integration guide will emerge at http://oxpedia.org/wiki/index.php?title=AppSuite:SAML_SSO_Integration.
