system is unable to interpret the SSO ticket received

Hi All,

I have implemented MSS(Webdynpro) and ESS on the NW 04 SR1.Backend is ECC 5.0.I have created the JCo connection for HR and FI for the ECC 50 system.

But ,I am getting an error:system is unable to interpret the SSO ticket received.

And,In one of the iview,I am getting RFC error:com.sap.mw.jco.JCO$Exception: (103) RFC_ERROR_LOGON_FAILURE: The system is unable to interpret the SSO ticket received

I am able to log in to the backend system by going thru the System Admin->Support->SAP Application->SAP Transaction..(it means the single sign on that I have configured is properly working.. )

Any suggestions???
