Configuring Samba Share Access Controls</A +></H1 +><P +>This section deals with how to configure Samba per share access control restrictions. +By default samba sets no restrictions on the share itself. Restrictions on the share itself +can be set on MS Windows NT4/200x/XP shares. This can be a very effective way to limit who can +connect to a share. In the absence of specific restrictions the default setting is to allow +the global user <SPAN +CLASS="emphasis" +><I +CLASS="EMPHASIS" +>Everyone</I +></SPAN +> Full Control (ie: Full control, Change and Read).</P +><P +>At this time Samba does NOT provide a tool for configuring access control setting on the Share +itself. Samba does have the capacity to store and act on access control settings, but the only +way to create those settings is to use either the NT4 Server Manager or the Windows 200x MMC for +Computer Management.</P +><P +>Samba stores the per share access control settings in a file called <TT +CLASS="FILENAME" +>share_info.tdb</TT +>. +The location of this file on your system will depend on how samba was compiled. The default location +for samba's tdb files is under <TT +CLASS="FILENAME" +>/usr/local/samba/var</TT +>. If the <TT +CLASS="FILENAME" +>tdbdump</TT +> +utility has been compiled and installed on your system then you can examine the contents of this file +by: <KBD +CLASS="USERINPUT" +>tdbdump share_info.tdb</KBD +>.</P +><DIV +CLASS="SECT2" +><H2 +CLASS="SECT2" +><A +NAME="AEN2880" +>16.1.1.
