Comment 14 for bug 1811439

My take on this is that the authentication_status.null_user for the BMC's capabilities (in the response) is set to 0h and this is telling us that the BMC does not support a null username. ipmipower seems to be actually handling this properly in the sense that since a null username is provided, i.e. no username, that it errors out since the BMC does not support this. ipmitool just returns when the username is not set and does not raise an error (take a look at the function ipmi_intf_session_set_username in https://github.com/ipmitool/ipmitool/blob/master/src/plugins/ipmi_intf.c).

So, seems like the BMC is not configured correctly if it is expected to work with a null username since the capabilities are telling us that this is not supported. I think we should have the firmware for the BMC updated so that authentication_status.null_username is set to 1h and ipmipower should then work from what I can tell.
