BSSV error

Hi All,

When we are testing BSSV, getting following error:

=====

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmln                                                                  s:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsd="http://www.w3.o                                                                  rg/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><soapen                                                                  v:Header/><soapenv:Body><soapenv:Fault><faultcode xmlns:p55="http://docs.oasis-o                                                                  pen.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">p55:FailedAuthen                                                                  tication</faultcode><faultstring>com.ibm.wsspi.wssecurity.SoapSecurityException:                                                                   WSEC6521E: Login failed.

any suggestion on this would be of great help.
