passing user credentials in SOAP header

Hi

I have a scenario where I have to invoke the login web service first and then the createData webservice. The sessionID returned from the login web service, I have to send it as part SOAP header for the createData webservice.

Or,

I have to pass the user crendentials in the SOAP header

Example, like <s:Authentication>

<s:userid>USER</s:userid>

<s:password>USER</s:password>

</s:Authentication>

Any help appreciated.
