Troubleshooting Amazon Database Migration Service identity and access
Use the following information to help you diagnose and fix common issues that you might encounter when working with Amazon DMS and IAM.
Topics
I am not authorized to perform an action in Amazon DMS
If the Amazon Web Services Management Console tells you that you're not authorized to perform an action, then you must contact your administrator for assistance. Your administrator is the person that provided you with your user name and password.
The following example error occurs when the mateojackson IAM user
tries to use the console to view details about an Amazon DMS endpoint but does not have
dms: DescribeEndpoint permissions.
User: arn:aws-cn:iam::123456789012:user/mateojackson is not authorized to perform: dms:DescribeEndpoint on resource: my-postgresql-target
In this case, Mateo asks his administrator to update his policies to allow him to
access the my-postgresql-target endpoint resource using the
dms:DescribeEndpoint action.
I am not authorized to perform iam:PassRole
If you receive an error that you're not authorized to perform the iam:PassRole action, your policies must be updated to allow you to pass a role to Amazon DMS.
Some Amazon Web Services allow you to pass an existing role to that service instead of creating a new service role or service-linked role. To do this, you must have permissions to pass the role to the service.
The following example error occurs when an IAM user named marymajor tries to use the console to perform an action in
Amazon DMS. However, the action requires the service to have permissions that are granted by a service role. Mary does not have permissions to pass the
role to the service.
User: arn:aws-cn:iam::123456789012:user/marymajoris not authorized to perform: iam:PassRole
In this case, Mary's policies must be updated to allow her to perform the iam:PassRole action.
If you need help, contact your Amazon administrator. Your administrator is the person who provided you with your sign-in credentials.
I'm an administrator and want to allow others to access Amazon DMS
To allow others to access Amazon DMS, you must create an IAM entity (user or role) for the person or application that needs access. They will use the credentials for that entity to access Amazon. You must then attach a policy to the entity that grants them the correct permissions in Amazon DMS.
To get started right away, see Creating your first IAM delegated user and group in the IAM User Guide.
I want to allow people outside of my Amazon account to access my Amazon DMS resources
You can create a role that users in other accounts or people outside of your organization can use to access your resources. You can specify who is trusted to assume the role. For services that support resource-based policies or access control lists (ACLs), you can use those policies to grant people access to your resources.
