3.2. HTTP Authentication Overview

All requests to the Satellite API require a valid Satellite user name and password. The API uses HTTP Basic Authentication to encode these credentials and add to the Authorization header. For more information about Basic Authentication, see RFC 2617 HTTP Authentication: Basic and Digest Access Authentication. If a request does not include an appropriate Authorization header, the API returns a 401 Authorization Required error

Some base64 libraries break encoded credentials into multiple lines and terminate each line with a newline character. This invalidates the header and causes a faulty request. The Authorization header requires that the encoded credentials be on a single line within the header.
