We are trying to authenticate a client on remote vpn, through a Meraki Z1 teleworker appliance. The Z1 is sending a proper request, the Network Policy Server (ias) service is apparently authenticating the user because our NPS log shows that there is a Reason-Code of 0 in the audit log, however ias is returning Access-Reject back to the Z1 device.
I'm having a difficult time finding out WHY the ias service is sending Access-Reject, and it is to the point now where I think I need some kind of deep debugging output to see where the issue lay. Does anyone know how I might be able to get a deluge of log information out of the IAS service? Is there a specific way to enable that through the EventLog interface?
