Windows authentication

For Windows authentication, there is no need to define the <UserName> and <Password> tag in the property list.

Example

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
   <SOAP-ENV:Header>
      <XA:BeginSession xmlns:XA="urn:schemas-microsoft-com:xml-analysis" mustUnderstand="1"/>
   </SOAP-ENV:Header>
   <SOAP-ENV:Body>
   ...
      <Properties>
         <PropertyList>
         ...
         </PropertyList>
      </Properties>
   ...
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
