Release Sales Order from web service

Hi Team,

I have been trying to use the relase action in the ManageSalesOrder web service to no avail.  Everytime I use the xml to SOAPUI to send the request with sales order id, it kicks back saying not authorized.

I am using the ManageSalesOrder to do multiple other things through SOAPUI, this one seems to be the only stickler.

1. I can create the sales order just fine.

2. I can set the price of the item

3. Various other things.

Any thoughts would be greatly appreciated!!
