I said: ...seems ok on the clients but only - until a user 
want to change content of a file or copy that file..
But I should have been more specific: users can create new 
content(dirs, files) and remove stuff.
Problem almost certainly is not "permissions". It seems 
something with locking mechanism nfs <=> samba.
On Samba box when a user accesses the content directly in 
nfs4 mountpoint this problems do not occur.

NFS box and Samba box are in separate domains and I don't 
know just yet how to make them trust each other. NFS is IPA 
and Samba is just own BDC.
What even more peculiar - linux smb client also does not 
suffer from this problem. I can in Gnome edit files and do 
things that Win 7 refuses to do.
