NFS4 + ACL on TKL 11.3

Hey Folks!

Hardly tryin to get nfs4 and acl work... Does anyone has positive experience with it? 

I have nothing special - nfs-common and nfs-kernel-server configured as described in https://help.ubuntu.com/community/SettingUpNFSHowTo ..

I can't even look into the share due to id-mapping to nobody:nogroup... 

any hint?
