LDAP Support in Samba

1: What is LDAP?

+A directory is a type of hierarchical database optimised for simple query +operations, often used for storing user information. LDAP is the +Lightweight Directory Access Protocol, a protocol which is rapidly +becoming the Internet standard for accessing directories.

+ Many client applications now support LDAP (including Microsoft's Active +Directory), and there are a number of servers available. The most popular +implementation for Unix is from the University of Michigan; its +homepage is at http://www.umich.edu/~dirsvcs/ldap/.

+ Information in an LDAP tree always comes in attribute=value pairs. +The following is an example of a Samba user entry:

+uid=jbloggs, dc=samba, dc=org
+objectclass=sambaAccount
+uid=jbloggs
+cn=Joe Bloggs
+description=Samba User
+uidNumber=500
+gidNumber=500
+rid=2000
+grouprid=2001
+lmPassword=46E389809F8D55BB78A48108148AD508
+ntPassword=1944CCE1AD6F80D8AEC9FC5BE77696F4
+pwdLastSet=35C11F1B
+smbHome=\\samba1\jbloggs
+homeDrive=Z
+script=logon.bat
+profile=\\samba1\jbloggs\profile
+workstations=JOE
+

+ Note that the top line is a special set of attributes called a +distinguished name which identifies the location of this entry beneath +the directory's root node. Recent Internet standards suggest the use of +domain-based naming using dc attributes (for instance, a microsoft.com +directory should have a root node of dc=microsoft, dc=com), although +this is not strictly necessary for isolated servers.

+ There are a number of LDAP-related FAQ's on the internet, although +generally the best source of information is the documentation for the +individual servers.

+
+ +

2: Why LDAP and Samba?

+ Using an LDAP directory allows Samba to store user and group information +more reliably and flexibly than the current combination of smbpasswd, +smbgroup, groupdb and aliasdb with the Unix databases. If a need emerges +for extra user information to be stored, this can easily be added without +loss of backwards compatibility.

+ In addition, the Samba LDAP schema is compatible with RFC2307, allowing +Unix password database information to be stored in the same entries. This +provides a single, consistent repository for both Unix and Windows user +information.

+
+ +

3: Using LDAP with Samba

Install and configure an LDAP server if you do not already have +one. You should read your LDAP server's documentation and set up the +configuration file and access control as desired.
+

Build Samba (latest CVS is required) with:

+	./configure --with-ldap
+	make clean; make install
+

Add the following options to the global section of smb.conf as +required.
+
- ldap suffix
  + This parameter specifies the node of the LDAP tree beneath which +Samba should store its information. This parameter MUST be provided +when using LDAP with Samba.
  + Default: none
  + Example: ldap suffix = "dc=mydomain, dc=org"
  +
- ldap bind as
  + This parameter specifies the entity to bind to an LDAP directory as. +Usually it should be safe to use the LDAP root account; for larger +installations it may be preferable to restrict Samba's access.
  + Default: none (bind anonymously)
  + Example: ldap bind as = "uid=root, dc=mydomain, dc=org"
  +
- ldap passwd file
  + This parameter specifies a file containing the password with which +Samba should bind to an LDAP server. For obvious security reasons +this file must be set to mode 700 or less.
  + Default: none (bind anonymously)
  + Example: ldap passwd file = /usr/local/samba/private/ldappasswd
  +
- ldap server
  + This parameter specifies the DNS name of the LDAP server to use +when storing and retrieving information about Samba users and +groups.
  + Default: ldap server = localhost
  +
- ldap port
  + This parameter specifies the TCP port number of the LDAP server.
  + Default: ldap port = 389
  +
+
You should then be able to use the normal smbpasswd(8) command for +account administration (or User Manager in the near future).
+

+
+ +

4: Using LDAP for Unix authentication

+ The Samba LDAP code was designed to utilise RFC2307-compliant directory +entries if available. RFC2307 is a proposed standard for LDAP user +information which has been adopted by a number of vendors. Further +information is available at http://www.xedoc.com.au/~lukeh/ldap/.

+ Of particular interest is Luke Howard's nameservice switch module +(nss_ldap) and PAM module (pam_ldap) implementing this standard, providing +LDAP-based password databases for Unix. If you are setting up a server to +provide integrated Unix/NT services than these are worth investigating.

+
+ +

5: Compatibility with Active Directory

+ The current implementation is not designed to be used with Microsoft +Active Directory, although compatibility may be added in the future.
