[Samba] Samba Question

[Gerry Maddock]

I have a share access question for you. I have been running Samba 2.2.7 as
a PDC on my RH7.2 box for several years now. I just setup a new PDC
running Samba 3.0.10 on a FC3 box. I used to control read-write acces to
shares via samba like:
[TRData]
        path = /tr/TRData
        valid users = administrator, at IT, at fl, at tx, at eu, at ca, at ny, at wa, at uk
        write list = administrator, at IT, at FLTR
        force group = FLTR
        read only = no
        create mask = 0777
        directory mask = 0777

That would work fine when I was running Samba 2.2.7, but now it doesnt
work with Samba 3.0.10. What can I enter to my new smb.conf (3.0.10) to
get the shares to behave like they did when I ran 2.2.7?

Thanks in advance!!!
