=Basic information=
==Installation==
Install samba, samba-swat and ldap based authentication for samba using:
<pre>
sudo apt-get -y install samba samba-common smbclient gosa gosa-plugin-samba ldap-account-manager ldapscripts sadms smbldap-tools swat system-config-samba samba-doc samba-doc-pdf
</pre>
Note:
*You can enter kerebros values as 'localhost' everywhere, unless you actually know what value to configure.


==About configuration file==
In the default samba.conf file comments, both semi-colon(;) and hash(#) are used at various places.  The significance of these commenting characters is:
*'<tt>;</tt>' indicates suggested different default for particular value.
*'<tt>#</tt>' indicates that default value is being used, but user should know about it


==Testing configuration==
Use command '<tt>testparm</tt>' to check new samba configuration.  Using '<tt>testparm -s smb.conf.master &gt; smb.conf</tt>' to generate smb.conf is recommended for better performance.


==Documentation==
Find documentation for samba at '<tt>/usr/share/doc/samba-doc/htmldocs/Samba3-HOWTO/</tt>'
  



=Service configuration=
*To start samba in Ubuntu
*:<pre>
*::sudo service smbd start
*:</pre>
* To stop samba service
*:<pre>
*::sudo serivce smbd stop
*:</pre>
* To enable samba service for startup
*:<pre>
*::sudo update-rc.d smbd defaults
*:</pre>
* To disable samba service from startup
*:<pre>
*::sudo update-rc.d -f smbd remove
*:</pre>




=Guest access configuration=

==Basic guest configuration==

===Sections in smb.conf===
smb.conf file has four different types of sections:
* [global]
* [homes]
* [printers]
* and everything else
      
[global] section allows in setting default values for all other sections.  [homes] section comes into effect if no share-name matches with the request.  In such cases requested share is matched against usernames and if a matching user is found, home folder for the user is used as share path (by default).  This allows creating share for home folders for all users.



===Readonly share===
To create a read-only share with guest access use following steps:
# Rename '<tt>/etc/samba/smb.conf</tt>' to '<tt>/etc/samba/smb2.conf</tt>'
# Create new '<tt>/etc/samba/smb.conf</tt>' with following contents:
#:<pre>
#::     [global]
#::     workgroup = ClipCard
#::     server string = ClipCard File Sharing Server
#::     netbios name = ClipCard
#::     log file = /var/log/samba/log.%m
#::     max log size = 1000
#::     security = share
#::     
#::     [samba_shared]
#::     path=/samba_shared
#::     read only = yes
#::     guest ok = yes
#:</pre>
#Create folder for sharing files in read-only mode using '<tt>sudo mkdir -p /samba_shared/1</tt>'
#Allow everyone full-access on created folder using '<tt>sudo chmod -R 777 /samba_shared</tt>'.  Note that 777 is not required for read-only share.  555 would also suffice.
#Restart samba service to take new configuration into effect using '<tt>service smbd restart</tt>'
#Try to connect to created share using Guest username and no password using '<tt>smbclient //127.0.0.1/samba_shared -U%</tt>'
     


===Writeable share===
# Edit file created in previous section and change value of '<tt>read only</tt>' to '<tt>no</tt>'.
# Restart samba using '<tt>service smbd restart</tt>'
# Try smbclient again and try to upload a file using '<tt>put &lt;file&gt;</tt>'



=Configuring username and password based access=

To configure authenticated username and password based access to Samba shares use:
# Add or modify lines in smb.conf to include:
#:<pre>
#::    security = user
#::    passdb backend = tdbsam:/etc/samba/private/passdb.tdb
#::    idmap config * : backend = tdb
#:</pre>
# For a share such as [samba_shared] set '<tt>valid users</tt>' option as:
#:<pre>
#::    [samba_shared]
#::    ...Other options...
#::    valid users = saurabh
#:</pre>
# Note that '<tt>guest ok = yes </tt>' along with '<tt>valid users</tt>' is contradictory and in such cases '<tt>valid users</tt>' setting takes precedence.
# Use '<tt>mkdir -p /etc/samba/private</tt>' to create a private folder.
# Use '<tt>service smbd restart</tt>' to restart samba
# Use '<tt>smbpasswd -a saurabh</tt>' to add saurabh user to samba tdbsam database. 
# Try to access share using:
#:<pre>
#::    smbclient -U saurabh //127.0.0.1/samba_shared
#:</pre>
