Hi

We are using Samba4 and nfs3.

We're currently fighting a similar battle over of the nfs list about the 
incompatibility-with-everything-else'ness of nfs4 acls. It is not even 
possible to get group rw from a 0022 mounted umask. For this reason we 
have had to return to nfs3 and keep our posix acls which samba seems to 
respect. It is unfortunate that the nfs4 dev's have not listened to end 
users. The main aim seems to be to push to nfs4.1 at all costs.

The reply to this post says it all:

'The NFSv4 protocol does not support POSIX ACLs. It has its own
implementation of ACLs that is much more windows-like (yet not exactly
either)'

Maybe you could add an extra voice there?

Cheers and good luck,
Steve
