The setup consist of:
...
For the purpose of this pilot, we have enabled federated access to the dashboard of a demo OpenStack Cloud deployment and we are using a set of dummy users registered in the testbed IdP. Specifically, the pilot IdP proxy has been configured to authenticate users and communicate the result of the authentication to an OpenStack's Identity service (Keystone) using SAML assertions. Before passing the authentication results to OpenStack, the pilot IdP proxy contacts a COmanage instance, on which it some collaborations (COCOs) have been created that have a corresponding project in OpenStack for properly the mapping the of users: it attaches any additional entitlement regarding the users user's membership of the COs to the SAML assertion. At this point the new SAML assertion is passed to OpenStack and it is mapped to keystone user groups, based on which, the authenticating authenticated user can access cloud resources using their his/her federated ID.
There was no need to create local accounts on the cloud framework, ephemeral users are used instead: it was creates we created a set of mapping rules that, depending on the entitlements provided by COmanage (ownership to the managing COs with a precise roleand groups with users having specific rules in the CO), associate the external users to the right group defined into openstack, and after which each of them can access to a particular OpenStack project with different user rights (either admin or simple user).

| 3. | Enter your login credentials to authenticate yourself with the IdP of your Home Organisation. We will show three cases: a) an user belonging to aarc-yellow CO with admin role b) an user belonging to aarc-yellow CO with no particular roles c) an user belonging to aarc-blue CO with admin role |  | 4a|||||||
