Appendix A General Information

This appendix covers the following topics:

LDAP Overview

Messaging Server and Calendar Server products include object classes and attributes defined by the Lightweight Directory Access Protocol (LDAP) and extensions to the standard LDAP schema that extend the basic functionality of LDAP.

Initially developed at the University of Michigan, LDAP is a lightweight version of the X.500 Directory Access Protocol. LDAP has become an Internet standard for directory services running over TCP/IP.

One or more LDAP servers contain the data that make up the LDAP directory. An LDAP directory stores information in object-oriented hierarchies of entries. Each entry is uniquely identified by a distinguished name, or DN. The DN consists of the comma-separated sequence of attributes and values that specify the unique location of an entry within the directory information tree. This provides a path of names tracing the entry back to the top of the directory hierarchy.

Attribute Syntax

Directory data is represented as attribute-value pairs. Any specific piece of information is associated with a descriptive attribute.

Each attribute has a corresponding syntax definition. The syntax definition describes the type of information provided by the attribute.

Table A–1 Syntax Types


Syntax Method	Abbreviation	Definition
Binary	`bin`	Attribute values are binary
Boolean	`boolean`	Two values possible: Yes or No, True or False, On or Off
Case Exact String	`ces`	Values are case sensitive
Case Ignore String	`cis`	Values are not case sensitive
Telephone	`tel`	Telephone numbers (identical to cis, but blanks and dashes (-) are ignored
Distinguished Name	`dn`	Indicates values are DN's
Integer	`int`	Values are numbers
Operational	`operational`	Not displayed in search results

Required and allowed attributes for each object class are included in the object class listing.

Unless otherwise noted, attributes are assumed to be multi-valued, that is, more than one instance of the attribute can be specified. Attributes that are single-valued, that is, only one instance of the attribute can be specified, are noted as such in the Syntax heading, found in each attribute definition.

Object Identifiers

To meet LDAP and X.500 standards, all attributes and objects should have been assigned Object identifiers (OID's). An OID is a sequence of integers, typically written as a dot-separated string. The OID identifies who first filed the name of the object or attribute with the standards committee.

In some cases, objects and attributes listed in this document do not have an OID assigned to them yet.

Standard Time Zones

The following two tables lists the time zones recognized by Calendar and Messaging Servers first in alphabetical order, and then by offset from Universal Time Constant (UTC).

Note that in some countries, like Israel, daylight savings time is not always observed every year. The decision is made year-by-year. Also, some individual states in the United States do not observe daylight savings time.

This means that some time offsets will not be accurate unless the definitions are updated as needed in the respective systems (see individual product documentation for information about adjusting time zone offsets).

The following table lists the time zones in alphabetical order.
