SAML SSO Integrations
When you implement SAML single sign-on (SSO), it's important to consider:
Which system(s) will serve as the authoritative source for user profile information if there's ever a conflict between two or more sources.
What user profile attributes each application needs.
How user profile information will be distributed to the systems that need it.
Identity provider-initiated SSO
You typically set up a SAML federation by configuring SSO initiated by the service provider. The service provider returns a browser redirect so that the user authenticates using the IdP. After authentication, the browser redirects the user back to the service provider with a SAML assertion containing information about the authentication status. This is commonly used for consumer-facing scenarios.
You can also configure the IdP to initiate SSO instead of the service provider. In this scenario, the user invokes a URL on the IdP and is prompted to authenticate, then is redirected to the service provider with a SAML assertion. This is commonly used in enterprise scenarios.
