Hi Pritha, thanks for the answer. Even changing to Principal I still get the MalformedPolicyDocument. I tested with aws cli versions 1 and 2, both returning the error message. I put JSON in several validators to see if there were any errors and it seems to be okay. I don't know if I'm missing something in the aws cli configuration, my credentials are: [default] aws_access_key_id = < admin-api-user key > aws_secret_access_key = < admin-api-user secret > And my config: [default] region = US output = json And I checked that no rule with the same same exists. With the example python from the page https://docs.ceph.com/en/latest/radosgw/STS/ it worked (it has an extra "]" that needs to be removed in the policy_document variable). Thanks again, Marcelo.

I'm having a hard time trying to get the STS to work. I want to give a user "someuser" the ability to assumerole. I don't know if I got it wrong how to do it, or if my json is spelled wrong.
