Would this exact configuration work ? Should I set any other permission in order to have the user from the wheel group to mount drives? Thanks for posting your configuration. PS: One thing I've noticed with this specific user, whenever he creates something the file/directory will show owner:username group:username. I've used the command "groups" as well as chpass I think and they gave me only one group for this username... wheel. Why doesn't wheel appear as the group owner for stuff that username is creating ? >>Thank you >>Dany >> >>Harald Schmalzbauer wrote: >> >> >>>On Wednesday 31 December 2003 10:08, Andrew L.
