Thanks Brian. See below. I'll send the log file to your email. Is it under /usr/local/gt4.0.6/var ?

1) User certificate expired. Tried to create a new one, sign and use it. Did not work. So we tried creating a new authority.
2. Did create both host and user certificates.
3. New for both host and user.
4. Yes we restated the Globus server.
