What action must the customer's IdP team take if a user is not assigned to the application?

To ensure that a user has the necessary access to a specific application, the customer's Identity Provider (IdP) team must assign permissions to that user. This assignment is critical because it defines what resources and functionalities within the application the user can access. Without the appropriate permissions, even if a user is authenticated, they will not be able to leverage the features or data that the application offers.

In the context of user management and access control within Identity Providers, assigning permissions is a common administrative task that makes sure users are authorized to use the applications relevant to their roles. It establishes the necessary level of access based on the user's responsibilities, thus enhancing security and operational efficiency within an organization.

Additionally, other actions mentioned, such as changing application server settings, resetting passwords, or updating the user's email address, do not directly address the issue of application assignment. These actions may be necessary in different contexts, but they do not solve the core issue of granting application access through permission assignments.
