Yes:
root at samba-dc:~# ping -c1 data2
PING data2.ea.linuxcs.com (192.168.1.81) 56(84) bytes of data.
64 bytes from 192.168.1.81 (192.168.1.81): icmp_seq=1 ttl=64 time=0.514 ms

root at samba-dc:~# smbclient -NL data2
Anonymous login successful

However, one of the shares I set up is inexplicably missing from this list:

[home]
    comment = Home Directories
    path = /data/home
    guest ok = no
    browseable = no
    writeable = yes
    create mask = 0700
    directory mask = 0700
    follow symlinks = yes

[share]
    comment = Share Directory
    path = /data/share
    guest ok = no
    browseable = yes
    writeable = yes
    create mask = 0770
    directory mask = 0770
    # This can slow down large directory listings
    # hide unreadable = yes
    # inherit permissions = yes
    follow symlinks = yes

[software]
    comment = Location for .msi files to be automatically installed by AD
    path = /data/software
    guest ok = no
    browseable = yes
    writeable = yes
    create mask = 0770
    directory mask = 0770
    follow symlinks = yes

Hmmm, that one could be tough, as mduffy isn't set up to log on to the 
DC (and won't be), and the only other linux host I have in the domain 
right now is data2

Let me increase the Samba log level on data2 to see if anything else 
shows up in log.smbd. If that fails, I can quickly spin up another linux 
host to use for this.

Meanwhile, just to test:

root at data2:/data# su - mduffy
su: warning: cannot change directory to /home/EA/mduffy: No such file or 
directory

How/where is it deciding to make the home directory /home/EA/mduffy?  I 
don't have anything set up under the user's Profile. Is this a default 
location built into Samba?  For that matter, how is it deciding the 
default shell is /bin/false?
