Here it is. As I said, I'm new at Samba.
This is really borrowed from the sample provided with FC4. I've edited out
everything that I had commented out and the commentary in the interest of
size.
Thank you all for all the help.
[global]
netbios name = Shadow1
workgroup = LANGROUP
log level = 2
server string = Samba Server
printcap name = /etc/printcap
load printers = yes
log file = /var/log/samba/%m.log
max log size = 50
security = user
password level = 8
username level = 8
encrypt passwords = yes
smb passwd file = /etc/samba/smbpasswd
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
dns proxy = no
#============= Share Definitions =====================
idmap uid = 16777216-33554431
idmap gid = 16777216-33554431
template shell = /bin/false
winbind use default domain = no
username map = /etc/samba/smbusers
security = user
; encrypt passwords = yes
; guest ok = no
; guest account = nobody
[homes]
comment = Home Directories
browseable = no
writeable = yes
printable = no
[tmp]
comment = Temporary file space
path = /tmp
read only = no
; public = yes
[public]
path = /TheArray
writeable = yes
browseable = yes
; guest ok = yes
; public = yes
valid users = judith smitty
printable = no
Hopefully, this isn't too screwed up!
Thanks again,
Smitty
