I am trying to create new signed certificates on a Corporate Firewall 2008 Smoothwall machine and I am getting an error that says
Error - Unable to create certificate, possibly due to a duplicate Subject.
I think this is a flavor of OpenSwan. I can find nothing with this error text on Smoothwall's support site.
I do have shell access if you want to suggest any command line work.
Underneath the create cert dialog on the screenshot are all my certificates that have been created in the past without any problem (not going to show those).
