Object Classes and Attributes


his appendix describes the schema elements most commonly used in the directory server. Most of the schema elements used in the directory server are part of the standard LDAP protocol, which is in turn based on the X.500 standard. However, some of the directory server's object classes and attributes are extensions created by Netscape® for use with its implementation of LDAP. If an object class or attribute was created by Netscape and is not part of the standard LDAP schema, a note is made in the description of that object or attribute.

This chapter includes

Schema definition

The directory server schema defines the type of information that can be stored on a directory server entry. This definition is provided by the following types of schema elements:

A consistent schema

It is important that you use a consistent schema within your directory server because LDAP clients locate entries in your directory by searching for object classes or attributes and their associated values. If you use an inconsistent schema, then it becomes virtually impossible to locate information in your directory tree.

Further, LDAP clients are designed to work with a specific, well-defined schema. For the most part, the schema that these LDAP clients are designed to work with is the standard LDAP schema which, itself, is based on the X.500 standard. For this reason, most LDAP-based directory services begin with the standard LDAP schema, but then they add to it as they discover site-specific needs that are not met by the standard schema.

The Netscape LDAP schema takes this approach, as well. Most of the schema elements in this appendix are based on the LDAP standard. However, Netscape has extended the schema to allow for directory activities that are not otherwise supported by the standard LDAP implementation. All of these extensions are noted in the following schema description. In addition, Netscape ships LDAP clients that expect the schema as defined in this appendix.

You can enforce your directory server's schema by turning schema checking on. When schema checking is turned on, you cannot add an object class or attribute to your directory server that is not a recognized part of the schema. For more information on schema checking, see the Administrator's Guide.

Note that schema checking is not supported for the Netscape local directory.

Customizing the schema

You do not have to use the schema that is described here. In fact, it is assumed that you will extend this schema to support your own site's requirements. This is perhaps one of the most common activities surrounding a new directory server installation.

For a discussion on how to extend your schema, see the webpage at the following URL:

http://www.netscape.com/eng/server/directory/1.0/dsextension.html

Building custom clients

As you extend your schema, it is important to remember that will have to start building customized LDAP clients to manage and use your directory. This is because the standard LDAP clients will not know the names of your new schema elements or what type of information they expect to be stored on these new elements. This is a problem that only gets worse as the clients become more sophisticated and begin to offer a graphical look at your directory contents, or to perform sophisticated directory management capabilities.

To aid you in developing customized LDAP clients, Netscape ships several command-line LDAP clients with the directory server. You can use the command-line tools to build rudimentary tools such as shell scripts to help you perform batch operations on your directory tree. You can also use these same command-line tools with cgi scripts that allow you to perform directory management activities using a webserver and your web browser.

In addition, Netscape provides the LDAP client SDK to allow you to quickly build LDAP clients using the C or Java programming languages.

For more information, on the command line client tools, see the Administrator's Guide. For more information on the LDAP client SDK, go to

http://developer.netscape.com/library/documentation/index.html

A note about attribute values

Perhaps one of the more confusing aspects about an LDAP schema is that you can place any data that you want on any attribute value. LDAP and the directory server place no restrictions on the data format, length, or type that you associate with individual attributes (other than some minimal syntax definitions that are used strictly for searching and pattern matching purposes). For example, when you represent a telephone number in your directory tree, you can legally represent it in any of the following ways:

	(408) 555-5555
	408-555-5555
	1-408-555-5555
	1.408.555.5555
	555-5555
This free-form data model provides you with maximum flexibility when you design your data policy. However, the caveat to this data model is that although the directory server and the LDAP protocol do not care about your data format, your LDAP clients do care about the representation of the data in your directory tree. This is especially true of graphical user interface clients that must display directory data in rigid-length fields. The format of your directory data is also important to the user who is searching your directory tree for a particular value. For example, if the user is searching for a telephone number in the form

	(408) 555-5555
but you have stored telephone numbers in the format

	1.408.555.5555
then the user may have difficulty locating the actual entry for which she is searching. For these two reasons, it is important that you be as consistent as possible when storing data in your directory tree. Pick a format and stick with it. When managing the data in your directory tree, keep in mind not so much what the directory server requires, but rather what your LDAP clients and the users of your directory expects to find there. Doing so will vastly improve the usability of your directory data.

Object classes

Object classes define the type of data an entry can contain. Each object class has a defined set of required and optional attributes. An object class may be a subclass of another object class, in which case the required attributes of the latter class are also required attributes of the former class.

Object classes are defined in the directory server NSHOME/slapd-server/config/slapd.oc.conf file, where NSHOME is the directory where you installed your server.

Attributes

Attributes hold information about a specific descriptive aspect of the entry. Each attribute consists of an attribute type and an attribute value. The attribute type identifies the class of information given by that attribute (for example, telephone number). The attribute value is the particular instance of information appearing in that entry (for example, 555-1999).

Originally, attributes were defined using long names, such as commonName; however, the standards have changed to allow the use of abbreviations. For example,

	cn
is the abbreviation for

	commonName
If an attribute has an abbreviation, the abbreviation is given in the description of the attribute and may be used interchangeably with the full name in the list of attributes for an object class.

Required versus optional attributes

Object classes usually contain at least one required attribute, and they always contain one or more optional attributes. When an attribute is required, then attempts to add an entry to the directory without the required attribute results in an object class violation; the attempt to add the entry fails.

Optional attributes are attributes that you are allowed, but not required, to add to the directory entry. If you attempt to add an attribute to an entry that is neither required or allowed according to the entry's object class definition, then the directory server will return an object class violation.

Note that the concept of a required or allowed attribute is meaningful only if schema checking is turned on. If schema checking is turned off, then you can add (or fail to add) any attribute to your directory; the directory server will make no attempt to ensure that the data you are adding to your directory conforms to the schema.

It is strongly recommended that you run your directory server with schema checking turned on.

Object Class Definitions

The following sections describe the most common object classes that are used in the directory server. Most object classes are defined by the X.500 standard. In addition, Netscape provides some additional object classes for use with its LDAP implementation. Netscape also extends many of its object classes with new attribute definitions. The following types of object classes are described here:

Groups

The following two object classes describe entries representing an unordered set of names that represent individual objects or other groups of objects. Membership of a group is static: only administrative action can modify a group (such as adding a member), the membership is not determined dynamically each time a reference is made to the group. Each object class contains attributes that describe the group and its members. The two object classes described here are groupOfNames and groupOfUniqueNames.

Attribute definitions

The following define the most common attributes used to describe an entry in the directory tree. To determine which attributes are required and allowed for each object class, see "Object Class Definitions."

Each attribute has a corresponding syntax definition that describes the nature of the attribute information. This syntax is important only when the directory server is sorting and pattern matching; there is nothing to otherwise prevent you from, for example, placing a telephone number on an attribute that expects a distinguished name. For more information about attributes and attribute values, see "A note about attribute values."

The possible attribute syntaxes are

administratorContactInfo
Provides a URL to information about the person responsible for administering the Netscape server. This attribute is a Netscape extension used by the netscapeServer object class.

o=Ace Industry, c=US
Syntax: cis
adminURL
Provides the URL to the administration server through which you can manage the Netscape server. This attribute is a Netscape extension used by the netscapeServer object class.
