## API Request Parameters

### LDAPUsername

Is AD/LDAP username to login. Application must ask user for this value to successfully obtain rotating access credentials from AssumeRoleWithLDAPIdentity.

	return nil
}

// Sign given request using Signature V2.
func signRequestV2(req *http.Request, accessKey, secretKey string) error {
	signer.SignV2(*req, accessKey, secretKey, false)
	return nil
}

// Sign given request using Signature V4.
func signRequestV4(req *http.Request, accessKey, secretKey string) error {
	// Get hashed payload.
	hashedPayload := req.Header.Get("x-amz-content-sha256")

This includes adding the description of the changes to the `accepted-public-api-changes.json` file, and providing a reason for each change.
You can add the changes to any place in the file, e.g. at the top.

3. Make sure the file with accepted changes is sorted.\
Use the `./gradlew :architecture-test:sortAcceptedApiChanges` task to sort the file.

        // Threshold of 0 should be accepted
        request.threshold(0);

        assertEquals(0, request.threshold());
    }

    @Test
    public void testThresholdWithNegative() {
        CurlRequest request = new CurlRequest(Method.GET, "https://example.com");

        // Negative threshold should be accepted (though may not make sense)
        request.threshold(-1);

				m[key] = strings.Join(value, ",")
				break
			}
		}
	}
	return nil
}

// Returns access credentials in the request Authorization header.
func getReqAccessCred(r *http.Request, region string) (cred auth.Credentials) {
	cred, _, _ = getReqAccessKeyV4(r, region, serviceS3)
	if cred.AccessKey == "" {
		cred, _, _ = getReqAccessKeyV2(r)
	}
	return cred
}

- **S3Client**: AWS SDK v2, `s3://bucket/path`, properties: `endpoint`, `accessKey`, `secretKey`, `region`
- **GcsClient**: Google Cloud SDK, `gcs://bucket/path`, properties: `projectId`, `credentialsFile`, `endpoint`
- **StorageClient**: MinIO SDK, `storage://bucket/path`

### Services

- **UrlQueueService**: URL queue management (FIFO), duplicate detection
- **DataService**: Access result persistence, iteration

* Processing data:
    * For example, let's say you receive a file that must go through a slow process, you can return a response of "Accepted" (HTTP 202) and process the file in the background.
