The INDIGO Identity and Access Management service

The INDIGO Identity and Access Management Service provides a layer where identities, enrollment, group membership and other attributes and authorization policies on distributed resources can be managed in an homogeneous way, supporting identity federations and other authentication mechanisms (X.509 certificates and social logins).

The IAM service has been succesfully integrated with many off-the-shelf components like Openstack, Kubernetes, Atlassian JIRA and Confluence, Grafana and with key Grid computing middleware services (FTS, dCache, StoRM).


  • Authentication: The IAM supports authentication via SAML IdPs or identity federations, OpenID Connect providers and X.509 certificates.
  • Enrollment: The IAM provides enrollment and registration functionalities, so that users can join groups/collaborations according to well-defined flows.
  • Attribute and identity management: The IAM provides services to manage group membership, attributes assignment and account linking functionality.
  • User provisioning: the IAM provides endpoints to provision information about users identities to other services, so that consistent local account provisioning, for example, can be implemented.

Service access options

IAM as a service

INFN provides IAM as a service to partner research communities. In this scenario, a dedicated IAM instance is deployed on the INFN infrastructure and configured according to the community needs. INFN takes care of keeping the service operational and up-to-date, while administrative control on the IAM instance is granted to the community.
