What step should be taken after the IdP redirect in the authentication flow?

In the authentication flow involving an Identity Provider (IdP) redirect, the step that follows the redirect is the transmission of the authentication token back to the client connector. When a user is redirected to the IdP for authentication, they typically enter their credentials and, upon successful verification, the IdP generates an authentication token. This token is crucial as it contains the information needed to identify the user and grant them access.

The Zscaler Client Connector then receives this authentication token, which it uses to verify the user's identity and establish a secure session. This process ensures that the user's access to resources is based on validated credentials, maintaining security and appropriate access controls.

The other options suggest actions that either don’t fit the flow after the IdP redirect or are unrelated to the process of obtaining the authentication token. For instance, logging out and re-attempting authentication or entering a new password would not occur immediately after the IdP redirect; rather, these actions would be responses to failed authentication attempts or session management issues. By focusing on the authentication token's retrieval and its use by the client connector, the process aligns with the intended security framework established by the integration of the Zscaler solution with IdP systems.
