    // The SHAREPOINT_NTLM_DOMAIN would be "mycompany.com"
    // The SHAREPOINT_HTTPS_DOMAIN would be "xyzoffice.mycompany.com"
    // Also, the SHAREPOINT_USERNAME would be just the name, not a full email address.
    // for example, "chilkat" instead of "chilkat@mycompany.com"

    // Login, Password, LoginDomain, and NtlmAuth properties.

    // -------------------------------------------------------------------------
    // The more common case is to use SharePoint Online authentication (via the SPOIDCRL cookie).
    // If so, do not set Login, Password, LoginDomain, and NtlmAuth, and instead
    // establish the cookie as shown at SharePoint Online Authentication
