SAML2 IDP Initiated SSO

Background

PicketLink IDP supports SAML2 SP-Initiated SSO and SAML 1.1 IDP-Initiated SSO. There is a requirement to support SAML2 IDP-Initiated SSO.

Right now, in the absence of SAML2 request/response, the IDP moves to a SAML 1.1 workflow as described in https://docs.jboss.org/author/display/PLINK/SAML+v1.1

A change would be to make it configurable at the IDP to use SAML2 IDP initiated workflow in the absence of SAML2 request/response payload.

Available in 2.6.0.CR1 and later.

Targeted for PicketLink v2.6.0.Final
