Standard Attribute Types

Apple Computer has defined a series of standard attributes. Developers can define their own attributes (known as native attributes). An attribute can be required or optional. Each record type defines the attributes that it requires.

Open Directory clients are responsible for interpreting the value of any particular attribute. All configuration and discovery of information in the directory service can be accomplished by requesting the appropriate attribute value.

Table 1-2 lists some of the standard attribute types. See the Open Directory Reference section for the complete list of attributes. Constants for attributes that start with kDS1 represent attributes that can only have one value; constants for attributes that start with kDSN represent attributes that can have multiple values.
