SSO Single sign-on allows you to login using your Organization credentials. CircleHD single sign-on (SSO) is based on SAML 2.0. CircleHD acts as the Service Provider (SP), and offers automatic user provisioning. You do not need to register explicitly to be a user on CircleHD Portal. Once CircleHD receives a SAML response from the Identity Provider (IdP), it checks if this user exists. If the user does not exist, CircleHD creates a user account automatically with the received name ID provided this is enabled in Portal Security Settings. CircleHD can also work with other Service Providers such as PingOne, Okta, Centrify, Shibboleth, Gluu, OneLogin, Fugen and Symplified and ADFS 2.0 SAML implementation.
