Can I change the default unix attributes that QAS has selected for all unix-enabled users
Yes in the Control Center. Open the QAS Control Center. Select 'Preferences' from the menu on the left hand side. From there you will see 'Global Unix Options'. Click the drop down arrow to expand 'Global Unix Options'. Click 'Modify Global Unix Options' in the top corner. From there you can make any changes they like to the default Unix attributes.
