The database user is mapped 1:1 to the source Identity and Access Management (IAM) identity. For more information about IAM identities, see IAM Identities (users, user groups, and roles) in the Amazon Web Services Identity and Access Management User Guide.

The Identity and Access Management (IAM) identity that runs this operation must have an IAM policy attached that allows access to all necessary actions and resources. For more information about permissions, see Using identity-based policies (IAM policies) in the Amazon Redshift Cluster Management Guide.
