NTName at Qlikview Access by default set to Qlikview instead of os User name

[priyanka08]

I have implemented the section access like  if login  it should display certain tab only and hide others which is working fine on local desktop system.

but once I checked the same on access point it take  NTNAME as reg1\qlikview instead of reg1\priya

thats why section access not able to hide tab . 

Is there is any such settings in Qlikview access point
