Can't access ifolder 3 on oes 1 anymore, because the certificate is expired.

Now Within Yast I select Security and Users, CA Management, all I see in the
CA List is the Yast_Default_CA. If I highlight the Yast_Default_CA and click
Enter CA, I am asked for a password. I enter in the root password, but it
does not accept it. Can't remember I gave in a password for this during the
installaton. What is this password?
How to proceed and get ifolder 3 working again?
