This derived key token's parent cannot be found

[Sreedhar]

Hi,

I am working on the Application which will use wse2.0 to get the data from
the server and when I hosted in sharepoint which has wse3.0, I am getting the
following error after some period of time.

Unknown exception
System.Web.Services.Protocols.SoapHeaderException:
Microsoft.Web.Services2.Security.SecurityFault: The specified source for the
derivation is unknown ---> System.Exception: WSE512: This derived key token's
parent cannot be found. The reference to the parent token follows:
<wsse:SecurityTokenReference
