HI Marek,
Thanks for your reply.
Here are the two uses cases I want to test

OS: Ubuntu 14.04 LTS/ Openstack Juno

Use Case # 1: . I aim to test  an OS-FEDERATION where a Keystone is 
acting  as a Service Provider(Ks-SP)  and a Shibboleth installation  
that is acting as an Identity Provider(IdP) .
                         When a user authentication is issued on the 
Ks-SP then the Ks-SP asks the IdP(Shibboleth) to identifty this user.
                         Once the user is correctly identified then a 
token is generated by the Ks-SP.  I tried to configure the shibboleth by 
following the tutos from openstack website but I still have issue with 
the metadata on the Service Provider.
                         Any advice or idea is welcome. I am sure there 
is something I 'm doing bad but where:-(


Use Case # 2: The second step will be testing a Keystone2Keystone 
authentication. One Keystone  acting as an Identity Provider(Ks-IdP) and 
the another one acting as a Service Provider(Ks-SP). But for this purpose
as I understood using Keystone as an IdP is not possible before the Kilo 
version. But this use case is not urgent for the moment.

Thanks
Regards
Alexis
