nfs share user group

[Lance Hoffmeyer <lance@augustmail.com>]

I created a file server with a pub directory and a data directory

/pub/data

I then created a group share of which I (lance) am a member and made
pub and data of group (share).  I have made /pub and /pub/data rwx
for group 'share'.  I also have a user account on the server where
I am a member of the group 'share'.

In the exports file I created /pub M1(rw)


I have a machine called M1.  
There is a user 'lance'.

On this machine a mount the file server

mount server:/pub /mnt/server   


but when I go to /mnt/server/pub/data from M1
I don't have write permission.  

Why is this?  I thought I understood group permissions but
maybe not (obviously).

What permissions do I need set on /pub/data so that
anyone listed as 'share' on M1 can write to this directory on
the server?
