Steve can access the mounted folder. I can live with that but the acl 
still isn't working:

lynn2 has authinticated by Kerberos

root@hh3:~# setfacl -d -m g::rw /home/CACTUS/dropbox
root@hh3:~# mount -t nfs hh3:/home /mnt -o sec=krb5
lynn2@hh3:/mnt/CACTUS$ ls -la
total 28
drwxr-xr-x  6 root   root         4096 2012-02-27 14:24 .
drwxr-xr-x  4 root   root         4096 2012-02-18 18:52 ..
drwxrws---  3 root   debusers     4096 2012-02-29 15:31 dropbox
drwxr-xr-x 20 lynn2  debusers     4096 2012-02-26 16:43 lynn2
drwxrwxrwx  5 root   root         4096 2012-02-29 14:19 profiles
drwxr-xr-x  4 steve2 Domain Users 4096 2012-02-29 14:36 steve2

lynn2 then crates a file in the mount called l3:

lynn2@hh3:/mnt/CACTUS$ ls -la /home/CACTUS/dropbox/
total 20
drwxrws---+ 3 root  debusers 4096 2012-02-29 15:31 .
