Abstract >+ >+This document defines a schema for representing DHCP configuration in an >+LDAP directory. It can be used to represent the DHCP Service >+configuration(s) for an entire enterprise network, a subset of the >+network, or even a single server. Representing DHCP configuration in an >+LDAP directory enables centralized management of DHCP services offered >+by one or more DHCP Servers within the enterprise. >+ >+2. Conventions used in this document >+ >+The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", >+"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this >+document are to be interpreted as described in RFC-2119 [ ]. >+ >+In places where different sets of terminology are commonly used to >+represent similar DHCP concepts, this schema uses the terminology of the >+Internet Software Consortium's DHCP server reference implementation. >+For more information see www.isc.org. >+ >+3. Design Considerations >+ >+The DHCP LDAP schema is designed to be a simple multi-server schema. The >+ >+ >+ >+M. Meredith et al. Expires December 2001 [Page 1] >+ >+ >+ >+ >+ >+INTERNET-DRAFT LDAP Schema for DHCP 16 June 2001 >+ >+ >+intent of this schema is to provide a basic framework for representing >+the most common elements used in the configuration of DHCP Server. This >+should allow other network services to obtain and use basic DHCP >+configuration information in a server-independent but knowledgeable way. >+ >+It is expected that some implementations may need to extend the schema >+objects, in order to implement all of their features or needs. It is >+recommended that you use the schema defined in this draft to represent >+DHCP configuration information in an LDAP directory. Conforming to a >+standard schema improves interoperability between DHCP implementations >+from different vendors. >+ >+Some implementations may choose not to support all of the objects >+defined here. >+ >+Two decisions are explicitly left up to each implementation: >+ >+First, implementations may choose not to store the lease information in >+the directory, so those objects would not be used. >+ >+Second, implementations may choose not to implement the auditing >+information. >+ >+It is up to the implementation to determine if the data in the directory >+is considered "authoritative", or if it is simply a copy of data from an >+authoritative source. Validity of the information if used as a copy is >+to be ensured by the implementation. >+ >+Primarily two types of applications will use the information in this >+schema: 1. DHCP servers (for loading their configuration) 2. Management >+Interfaces (for defining/editing configurations). >+ >+The schema should be efficient for the needs of both types of >+applications. The schema is designed to allow objects managed by DHCP >+(such as computers, subnets, etc) to be present anywhere in a directory >+hierarchy (to allow those objects to be placed in the directory for >+managing administrative control and access to the objects). >+ >+The schema uses a few naming conventions - all object classes and >+attributes are prefixed with "dhcp" to decrease the chance that object >+classes and attributes will have the same name. The schema also uses >+standard naming attributes ("cn", "ou", etc) for all objects. >+ >+4. Common DHCP Configuration Attributes >+ >+Although DHCP manages several different types of objects, the >+configuration of those objects is often similar. Consequently, most of >+these objects have a common set of attributes, which are defined below. >+ >+ >+ >+M. Meredith et al.

This schema provides a >+generalized mechanism for supporting any of these proposals, by >+separating the definition of a server from the definition of >+configuration service provided by the server. >+ >+Separating the DHCP Server (dhcpServer) and the DHCP Configuration >+(dhcpService) representations allows a configuration service to be >+provided by one or more servers.

This work is based on the IETF document >+draft-ietf-dhc-ldap-schema-01.txt included in the doc directory. For the latest >+version of this document, please see http://home.ntelos.net/~masneyb. >+ >+First question on most people's mind is "Why do I want to store my >+configuration in LDAP?" If you run a small DHCP server, and the configuration >+on it rarely changes, then you won't need to store your configuration in LDAP. >+But, if you have several DHCP servers, and you want an easy way to manage your >+configuration, this can be a solution. >+ >+The first step will be to setup your LDAP server. I am using OpenLDAP from >+www.openldap.org. Building and installing OpenLDAP is beyond the scope of this >+document. There is plenty of documentation out there about this. Once you have >+OpenLDAP installed, you will have to edit your slapd.conf file. I added the >+following 2 lines to my configuration file: >+ >+include /etc/ldap/schema/dhcp.schema >+index dhcpHWAddress eq >+index dhcpClassData eq >+ >+The first line tells it to include the dhcp schema file. You will find this >+file under the contrib directory in this distribution. You will need to copy >+this file to where your other schema files are (maybe >+/usr/local/openldap/etc/openldap/schema/). The second line sets up >+an index for the dhcpHWAddress parameter. The third parameter is for reading >+subclasses from LDAP every time a DHCP request comes in. Make sure you run the >+slapindex command and restart slapd to have these changes to into effect. >+ >+Now that you have LDAP setup, you should be able to use gq (http://biot.com/gq/) >+to verify that the dhcp schema file is loaded into LDAP. Pull up gq, and click >+on the Schema tab. Go under objectClasses, and you should see at least the >+following object classes listed: dhcpClass, dhcpGroup, dhcpHost, dhcpOptions, >+dhcpPool, dhcpServer, dhcpService, dhcpSharedNetwork, dhcpSubClass, and >+dhcpSubnet. If you do not see these, you need to check over your LDAP >+configuration before you go any further. >+ >+You should now be ready to build DHCP. If you would like to enable LDAP over >+SSL, edit the includes/site.h file and uncomment the USE_SSL line. Now run >+configure in the base source directory. If you chose to enable LDAP over SSL, >+you must append -lcrypto -lssl to the LIBS= line in the file >+work.os/server/Makefile (replace os with your operating system, linux-2.2 on >+my machine). You should now be able to type make to build your DHCP server. >+ >+Once you have DHCP installed, you will need to setup your initial plaintext >+config file. In my /etc/dhcpd.conf file, I have: >+ >+ldap-server "localhost"; >+ldap-port 389; >+ldap-username "cn=DHCP User, dc=ntelos, dc=net"; >+ldap-password "blah"; >+ldap-base-dn "dc=ntelos, dc=net"; >+ldap-method dynamic; >+ldap-debug-file "/var/log/dhcp-ldap-startup.log"; >+ >+All of these parameters should be self explanatory except for the ldap-method. >+You can set this to static or dynamic. If you set it to static, the >+configuration is read once on startup, and LDAP isn't used anymore. But, if you >+set this to dynamic, the configuration is read once on startup, and the >+hosts that are stored in LDAP are looked up every time a DHCP request comes in. >+ >+When the optional statement ldap-debug-file is specified, on startup the DHCP >+server will write out the configuration that it generated from LDAP. If you are >+getting errors about your LDAP configuration, this is a good place to start >+looking. >+ >+The next step is to set up your LDAP tree. Here is an example config that will >+give a 10.100.0.x address to machines that have a host entry in LDAP. >+Otherwise, it will give a 10.200.0.x address to them. (NOTE: replace >+dc=ntelos, dc=net with your base dn). If you would like to convert your >+existing dhcpd.conf file to LDIF format, there is a script >+contrib/dhcpd-conf-to-ldap.pl that will convert it for you. Type >+dhcpd-conf-to-ldap.pl --help to see the usage information for this script. >+ >+# You must specify the server's host name in LDAP that you are going to run >+# DHCP on and point it to which config tree you want to use.
