How File Sharing InThe Samba?

How do you let Samba File Share?
How do I join Linux to Active Directory
Which part of the change file

Share specify the path where I
Where do I specify the file permissions
And where the user has not specified


[root@CentosFac ~]# vi /etc/samba/smb.conf
;       path = /var/lib/samba/netlogon
;       guest ok = yes
;       writable = no
;       share modes = 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
;       writable = yes
;       printable = no
;       write list = +staff
