admin user referenced in VPN Tunnel

Hello,

Some time ago I created a VPN tunnel and now I want to remove it. I can remove all references (policies, addresses, etc) except for one: my admin user (System Administrator).

I cannot find a way to remove this user from the VPN tunnel. I rebooted the FortiGate (60D) but the reference still remains.

The funny thing is I do not know how to connect a user to the tunnel. I have created another tunnel and there is no reference to an admin user.

Any ideas how to remove the user so that I can remove this tunnel?

Thanks in advance.

Kind regards,

Albert
