;       path = /var/lib/samba/netlogon
;       guest ok = yes
;       writable = no

# Un-comment the following to provide a specific roving profile share
# the default is to use the user's home directory
;       [Profiles]
;       path = /var/lib/samba/profiles
;       browseable = no
;       guest ok = yes


# A publicly accessible directory, but read only, except for people in
# the "staff" group
;       [public]
;       comment = Public Stuff
;       path = /home/samba
;       public = yes
