Unable to delete Amazon RDS instance

Question

I am unable to delete a RDS instance in my account.

The error message shows:

IAM Database Authentication is enabled in the DB Instance but it is not supported for the new configuration from the request. (Service: AmazonRDS; Status Code: 400; Error Code: InvalidParameterCombination; Request ID: 332fe09b-d6a0-47c8-84bc-d1f6881f34d2)

Answer 1

Have you tried disabling IAM Authentication before deleting the instance?
