Narrative:

Shortly after arrival at the gate in las vegas while deplaning passenger through the normal entrance door via the jetway, cabin smoke appeared. The aft flight attendant notified the flight deck of smoke and requested orders on how to evacuate/evacuation passenger. The captain responded to use the forward entry. I viewed the APU exhaust to determine that there was no fire, but suspect an oil leak as to the cause of smoke. Fire trucks and maintenance was immediately dispatched. Passenger were deplaned through the forward entry without incident or injury. The APU was examined and determined cause was an oil seal. No other action was required.
