The following table lists the supported authentication methods and indicates which methods are available for the OnSite and which are available for devices connected to serial or to KVM ports.An administrative user can use the Web Manager and any administrator can use the CLI utility for configuring an authentication method for the OnSite and for KVM and serial ports and for configuring authentication servers.The following table lists the supported authentication methods and indicates which methods are available for the OnSite and which are available for devices connected to KVM or serial ports. As mentioned elsewhere, KVM port authentication can only be configured when direct access to KVM ports is configured, and only the “Open” and “Custom” security profiles allow direct access to KVM ports to be configured.By default, logins to the OnSite and to devices connected to serial ports use Local authentication, and logins to devices connected to KVM ports use no authentication.All authentication methods except “Local,” “OTP,” and “OTP/Local” require an authentication server, which the administrator configures separately.
