Specifying Settings for IAM Role
[This step applies if you selected the IAM Role from current account option]
At the Role Settings step of the wizard, specify the name of the IAM role that you want to add. You must specify the name that the IAM role has in AWS.
If the IAM role was created with a path, you must specify the complete path and the name of the IAM role. For example, dept_1/s3_role.
