This solution applies to all Barracuda SSL VPNs.
If you have forgotten the ssladmin password, it can be reset by an administrator of the Barracuda SSL VPN from the appliance interface. The appliance UI is accessed through HTTPS over port 8443 or HTTP port 8000. Once you log in using the admin account, the ssladmin password can be reset under Administration > Reset SSL VPN Admin Password.
However the admin interface requires tech support to reset.
