Description This article describes the steps to disable MTLS temporarily via CLI.
Scope All FortiGates.
Solution

Enter the following commands in the CLI to disable mTLS (Mutual Transport Layer Security) authentication on the FortiGate:

 

config authentication scheme
    edit "mtls"
        set method cert
        set user-cert disable
    next
end

 

config authentication rule
    edit "mtls"
        unset active-auth-method
    next
end

 

config authentication setting
    unset user-cert-ca

end

 

Disabling mTLS authentication means clients will no longer need certificates to connect securely. Ensure the change is consistent with the security standards of the organization.
