-- Returns information about the access key IDs associated with the specified IAM user. If there are none, the operation returns an empty list.
--
--
-- Although each user is limited to a small number of keys, you can still paginate the results using the @MaxItems@ and @Marker@ parameters.
--
-- If the @UserName@ field is not specified, the user name is determined implicitly based on the AWS access key ID used to sign the request. Because this operation works for access keys under the AWS account, you can use this operation to manage AWS account root user credentials even if the AWS account has no associated users.
--
--
-- This operation returns paginated results.

-- | Creates a value of 'ListAccessKeys' with the minimum fields required to make a request.
--
-- Use one of the following lenses to modify other fields as desired:
--
-- * 'lakUserName' - The name of the user. This parameter allows (per its <http://wikipedia.org/wiki/regex regex pattern> ) a string of characters consisting of upper and lowercase alphanumeric characters with no spaces. You can also include any of the following characters: _+=,.@-
--
-- * 'lakMarker' - Use this parameter only when paginating results and only after you receive a response indicating that the results are truncated. Set it to the value of the @Marker@ element in the response that you received to indicate where the next call should start.
--
-- * 'lakMaxItems' - (Optional) Use this only when paginating results to indicate the maximum number of items you want in the response. If additional items exist beyond the maximum you specify, the @IsTruncated@ response element is @true@ . If you do not include this parameter, it defaults to 100. Note that IAM might return fewer results, even when there are more results available. In that case, the @IsTruncated@ response element returns @true@ and @Marker@ contains a value to include in the subsequent call that tells the service where to continue from.
