resolveAwsUniqueIds

Only valid when auth_type is iam. If set to true, the bound_iam_principal_arns are resolved to [AWS Unique

• IDs](http://docs.aws.amazon.com/IAM/latest/UserGuide/reference_identifiers.html#identifiers-unique-ids) for the bound principal ARN. This field is ignored when a bound_iam_principal_arn ends in a wildcard. Resolving to unique IDs more closely mimics the behavior of AWS services in that if an IAM user or role is deleted and a new one is recreated with the same name, those new users or roles won't get access to roles in Vault that were permissioned to the prior principals of the same name. Defaults to true. Once set to true, this cannot be changed to false without recreating the role.
