This article provide information on how to use the NetAPI probing method when SSO user test is failed due to WMI failure or when getting error as "SSO agent reported error - Error communication with OS error".

This error is caused by a WMI failure . When no user OS logged in, WMI gets a response as "getFields failed" which is represented by SonicOS as a negative number.
NetAPI can be used in this scenerio to avoid this error.
