A FATAL error has occurred. Part II

20 months ago I described a bizarre behaviour in webtop, now it is time to describe how to solve such problem (actually, customer have shared a simple testcase when user changes his password via Ctrl+Alt+Del on Windows computer and after that he need to clear cookies in order to force webtop to work). I do think the best option here is to replace actual user’s password by login ticket and the best candidate for that is com.documentum.web.formext.session.AuthenticationService:

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

import com.documentum.fc.client.IDfSession;
import com.documentum.fc.client.IDfSessionManager;
import com.documentum.fc.common.DfException;
import com.documentum.fc.common.DfLoginInfo;
import com.documentum.fc.common.IDfLoginInfo;

    public AuthenticationServiceCustom() {
        super();

    @Override
    public void login(HttpSession httpSession, String principalName,
            String docbase, HttpServletRequest req)

        replaceTicket(docbase);
    }

    @Override

            String docbase)

        replaceTicket(docbase);

        IDfSessionManager sessionManager = SessionManagerHttpBinding
                .getSessionManager();
        IDfSession session = null;
        try {
            int dotIndex = docbase.indexOf('.');
            if (dotIndex != -1) {
                docbase = docbase.substring(0, dotIndex);
