zfs allow - Can't mount after send / recv

Folks,
We have delegated zfs permissions to a non root user. This user wants to be able to snapshot filesystems in one zone, send / recv to a new zone and mount up the filesystem.

Permissions have been given as follows on both zones:

Zone1:

---- Permissions on mypool/myzone/myfs ---------------------------
Local+Descendent permissions:
        user zfsuser create,destroy,mount,mountpoint,receive,rename,send,snapshot

Zone2:

---- Permissions on wldistpool/itsaep/csd ----------------------------
Local+Descendent permissions:
        user zfsuser create,destroy,mount,mountpoint,receive,rename,send,snapshot

In zone1 I can su - zfsuser, snapshot, send and recv the dataset to zone2.
