The authorization header contains a token with a wrong audience

[prabhugsp]

I tried to use the tool to obtain the token for certain time.

I am not sure what should be the publisher and hubname so I left them empty and generated the token,

The Header looks like this in my request,

	<set-header name="Authorization" exists-action="skip">
		<value><![CDATA[SharedAccessSignature sr=https%3a%2f%2fenterpriseabc.servicebus.windows.net%2fpublishers%2f%2fmessages&sig=lkBJfO43mmYtWhwJcNxdK9YC2%2b1lXOWXpXdNdftnG90%3d&se=1498963116&skn=RootManageSharedAccessKey]]></value>
		<!-- for multiple headers with the same name add additional value elements -->
	</set-header>

Now when I test this using Developer Portal, I get this below error -

401 InvalidAudience: The authorization header contains a token with a wrong audience. TrackingId:0a8bdd15-e087-446f-bd69-4a08e9a34ce4_G31, SystemTracker:enterpriseabc.servicebus.windows.net:myendpoint/Order, Timestamp:6/11/2017 6:34:56 AM

When I removed the "%2fpublishers%2f%2fmessages" part from the header like shown below: I get a different error:

	<set-header name="Authorization" exists-action="skip">
		<value><![CDATA[SharedAccessSignature sr=https%3a%2f%2fenterpriseabc.servicebus.windows.net&sig=lkBJfO43mmYtWhwJcNxdK9YC2%2b1lXOWXpXdNdftnG90%3d&se=1498963116&skn=RootManageSharedAccessKey]]></value>
		<!-- for multiple headers with the same name add additional value elements -->
	</set-header>

401 InvalidSignature: The token has an invalid signature. TrackingId:799c3ad2-bb4e-4a55-bffd-f90c885023b8_G31, SystemTracker:enterpriseabc.servicebus.windows.net:myendpoint/Order, Timestamp:6/11/2017 6:37:29 AM

Is the Publisher and HubName Mandatory? If it isnt so what I am missing here..
Thank you!
