FortiGate 90E - lost access

[DeerTracks3512]

Hello,

I'm attempting to access an old FortiGate 90E that I had setup. I hooked up the console cable and was able to access it via putty using my old credentials. I attempted to use the command found in some documentation.

It seems like this command wasn't recognized. 

Here is the version of the firewall.

I'm pretty certain the firewall used to be configured so that someone could access the GUI through one of the ports on the firewall, but I cannot remember which port it could be. Is there a way for me to list the IPs each port is assigned to? What is the best way for me to access this firewall without messing up the configuration to much? 

Thank you!

Thank you for this response. I'm pretty certain that this account does have full privileges. Here is the output from the commands you specified. Is there anyway for me to explore all the users that are registered with this firewall?

you may have "multi-vdom" enabled in FortiGate, so try first to run "config global", then run the commands above

Yes. This was the issue! Thank you. I've been able to execute commands now.
