<p>
The relay state parameter name supported by the SAML 2.0 identity provider (IdP). When the end user is redirected
to the user access URL from the WorkSpaces client application, this relay state parameter name is appended as a
query parameter to the URL along with the relay state endpoint to return the user to the client application
session.

<p>
To use SAML 2.0 authentication with WorkSpaces, the IdP must support IdP-initiated deep linking for the relay
state URL. Consult your IdP documentation for more information.
