Sharepoint 2013 - ADFS - Azure Access Control

Hi.

I have deployed a Sharepoint 2013 site as an RP of an ADFS 2.1 (Windows server 2012).

ADFS is configured with two claim provider trust: Active directory ad Azure Acess Control (with Google as Identity Provider)

I can succesfully open sharepoint, after the authentication against ADFS>AD provider but I have the following error if I try to authenticate against the ADFS>Google provider:

A SamlAssertion requires at least one statement.  Ensure that you have added at least one SamlStatement to the SamlAssertion you are creating.

I think that ACS and ADFS are configured correctly because in the same ADFS I have a sencond RP (CRM 2013) and in it I can succesfully login after the Google authentication.

Anyone have an idea from where the error came from?

Thank you in advance.
