The Basic Properties section displays the standard elements in schema definition.
Attributes Description
Name Specifies the globally unique name.
Description Specifies an optional definition that describes the attribute and its contents. The analogous LDIF equivalent is "DESC".
OID Specifies the object identifier assigned to the schema definition. You can obtain a specific OID for your company that allows you to define your own object classes and attributes from IANA or ANSI.
Syntax Specifies the attribute syntax used. For example, the userPassword attribute uses the User Password Syntax whereas the authPassword attribute uses the Authentication Password Syntax.
Parent Specifies the schema definition’s parent or supertype if any. The analogous LDIF equivalent is "SUP".
Multivalued Specifies if the attribute can appear more than once in its containing object class.
Required By Class Specifies any object classes that require the attribute.
Allowed By Class Specifies any object classes that can optionally use the attribute.
Value Restrictions Specifies any restriction on the value of the attribute.
The Extra Properties section provides additional auxiliary information associated with the attribute.
Attributes Description
Aliases Specifies any shortform alias names, if any. In theory, you could have any number of shortform names as long as they are all unique. The analogous LDIF equivalent appears as the secondary element with the NAME element. For example, NAME ( ’sn’ ’surname’ ).
Origin Specifies the origin of the schema definition. Typically, it could refer to a specific RFC or company.
Stored in File Specifies the schema file that stores the definition in the <server-root>/config/schema folder.
Usage Specifies the intended use of the attribute. Choices are the following:
  • userApplications
  • directoryOperation
  • distributedOperation
  • dSAOperation
User-Modifiable Specifies if the attribute can be modified by an authorized user.
Obsolete Specifies if the schema definition is obsolete or not.
Matching Rules Specifies the associated matching rules for the attribute.
