Hi,
you should deinstall your old samba first.
And you should use "real" Samba 2.2.2 as available from
www.samba.org for red-hat. Sounds like you had old Samba packages flying around.
Easiest way to get a real good samba system is to do an upgrade-install of Version 5.1beta; it includes Samba 2.2.2 and every option (PDC, Quotas) is available in the easy e-smith way.
Worked very good at my home-server...
These howtos were sort of workarounds for the older e-smith versions.
