[Samba] Access control question

[Vicky Clarke]

In a samba share with domain authentication on an ext2 filesystem, is there 
any sensible way to allow creation of folders, files and so on inside it 
other than making the share directory world-writeable on the Unix system?

If not, are there other options for achieving this? I know I've heard about 
a Linux filesystem which has NT-style ACLs, but I've also heard that it's 
experimental, which doesn't sound ideal for something that's going to be 
pretty heavily used.

Thanks,
Vicky
