Part I. Red Hat OpenStack Platform identity providers

You can deploy one of two methods to authenticate for a user to authenticate to an identity provider (IdP):

  • You can connect the Red Hat OpenStack Platform (RHOSP) Identity service (keystone) to an IdP using LDAP (Lightweight Directory Access Protocol)
  • You can use federation, in which the IdP sends an assertion to the Identity service granting the user access to the cloud.

While LDAP is used as a central authority for identity management and authentication, federation can be used to build single sign-on solutions.

For information on connecting RHOSP services to an LDAP directory service by using either Active Directory (AD) or Red Hat Identity Manager (IdM), see the following resources:

For information on connecting RHOSP to IdM using Red Hat’s single sign-on (SSO) for a federated solution, see the following resources:
