Remove users from default account

[Janine Hannibal]

Hello,
I was asked by Richard Barlesi controller of Active Optical Networks to 
have all labusers removed from their account (9VAV426) with the 
exception of Mohamed Islam (mislam) and Tariq Haniff (haniff). I have 
tried removing the following labusers but cannot remove default project 
numbers. Please remove the following usernames from account 9VAV426:

pdhillon
vnovotny
bgray
dhopkins
novotny
psingh

Thank you for your assistance!
