Are u able to access the ONTAP S3 User/Buckets configuration. Also, do you have permissions to create an ONTAP S3 User. That is the first step. I assume that you are able to do so. Coming back to your question on how to query S3 User keys, there is no way you can do so. Infact, you can't get the keys using GET call. Instead, you will either need to create a new user that will give you a new access keys, or you need to use PATCH API of S3 Users where you can 'regenerate' new pair of keys for the existing user. So, basically given the security concerns, you will be able to see the user keys only at the time you create a new user or you regenerate the user keys. Once that is done, we can't do a query on the keys.
