JCO$Exception: (103) RFC_ERROR_LOGON_FAILURE

Hi all,

While create JCO connectivity, I encounter following error.

com.sap.mw.jco.JCO$Exception: (103) RFC_ERROR_LOGON_FAILURE: This system rejects all logons using SSO tickets.

The user authenticaltion method used is ticket, please note that it is successful in case of user/password.

Any clues.

Regards.
