Cross-Protocol share on 3PAR File Persona

We have 3PAR 8200's in each of our data centers. I don't play with them much, only when I have to.

I'm trying to create a cross-protocol (NFS+SMB read/write) using the SSMC. While I've created the share, Neither Windows nor Linux can write to it. The Linux nodes connect to AD using PBIS (formerly LikeWise).

What I need is to allow only "Domain Users" access to the share, either SMB for Windows or NFS for Linux.

I've read through File Persona User Guide but I've not been able to make it work.

Any ideas?
