RFC _ ERROR _ LOGON _ FAILURE: System received an expired SSO for a user


We're getting this error: "RFC _ ERROR _ LOGON _ FAILURE: System received an expired SSO" when accesing ESS content in portal. But the problem happens just with one user, it's ok with the others.

Please, what could be the problem?

Thanks a lot
