Failure to Grant Permissions to Create & Manage Access Keys on AWS console

Question

I wanted to allow a general user to create and manage access key on AWS console. To grant those permissions to that user, I created 2 IAM  policies below referring to https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_access-keys.html .

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "CreateOwnAccessKeys",
            "Effect": "Allow",
            "Action": [
                "iam:CreateAccessKey",
                "iam:GetUser",
                "iam:ListAccessKeys"
            ],
            "Resource": "arn:aws:iam::*:user/${aws:username}"
        }
    ]
}

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "ManageOwnAccessKeys",
            "Effect": "Allow",
            "Action": [
                "iam:CreateAccessKey",
                "iam:DeleteAccessKey",
                "iam:GetAccessKeyLastUsed",
                "iam:GetUser",
                "iam:ListAccessKeys",
                "iam:UpdateAccessKey"
            ],
            "Resource": "arn:aws:iam::*:user/${aws:username}"
        }
    ]
}

With the 2 IAM policies, still, that user could not create and manage access key on AWS console and found error messages as follows.

User: arn:aws:iam::711268734740:user/testuser is not authorized to perform: iam:ListAccessKeys on resource: user testuser with an explicit deny in an identity-based policy

How do I grant permissions to that user to create and manage own access keys?

Accepted Answer

Explicitly created deny statements take precedence over any allow rules for same action. Are you creating a statement such as "Action: iam:*, Effect: Deny" other than the two policies? The error message indicates that there is an explicit deny rule for "iam:ListAccessKeys".
