"Authentication not in correct format" when setting Azure Blob Service Properties (REST API)

Question

I am trying to set CORS rules on my Azure Blob Storage account by following these instructions.

This is the error I receive after making my request:

400 Authentication information is not given in the correct format. Check the value of Authorization header

Request URL:

PUT https://[MyAccountName].blob.core.windows.net/?restype=service&comp=properties

Request header:

x-ms-version: 2013-08-15
x-ms-date: Tue, 25 Feb 2014 13:02:00 GMT
Authorization: SharedKey
[MyAccountName]: [MyAccountKey]
Content-Length: 329
Host: [MyAccountName].blob.core.windows.net

Request body:

<?xml version="1.0" encoding="utf-8"?>
<StorageServiceProperties>
    <Cors>   
          <CorsRule>
                <AllowedOrigins>http://www.example.com</AllowedOrigins>
                <AllowedMethods>GET</AllowedMethods>
                <ExposedHeaders>x-ms-meta-data*,x-ms-meta*</ExposedHeaders>
                <AllowedHeaders>x-ms-meta-target*,x-ms-meta*</AllowedHeaders>
                <MaxAgeInSeconds>200</MaxAgeInSeconds>
        </CorsRule>
    <Cors>
</StorageServiceProperties>

For people reaching this page and wondering why you get this error even though you are using a Shared Access Signature URL, then you most likely are sending YOUR APP token to Azure. Make sure to NOT include the Authorization header in this case.
