Managing Attributes
Chapter 9 Extending the Directory Schema 339
Creating Attributes
You can use Directory Server Console to create new attributes. After adding new
attributes to your schema, you must create a new object class to contain them. See
“Creating Object Classes,” on page 343 for information.
To create a new attribute:
1.
Display the Attributes tab.
This procedure is explained in “Viewing Attributes,” on page 338.
OID The object identifier of the attribute.
An OID is a string, usually of dotted decimal numbers, that uniquely identifies an
object, such as an object class or an attribute. If you do not specify an OID, the
Directory Server automatically uses attribute_name
-oid
. For example, if you
create the attribute
birthdate
without supplying an OID, the Directory Server
automatically uses
birthdate-oid
as the OID.
For more information about OIDs, or to request a prefix for your enterprise, send
mail to the IANA (Internet Assigned Number Authority) at iana@iana.org or visit
the IANA website at: http://www.iana.org/.
Syntax The attribute syntax:
• Case Ignore String—Indicates that values for this attribute are not case
sensitive.
• Case Exact String—Indicates that values for this attribute are case sensitive.
• Distinguished Name—Indicates that values for this attribute are DNs.
• Binary—Indicates that values for this attribute are binary.
• Telephone Number—Indicates that values for this attribute are in telephone
number format.
• Integer—Indicates that valid values for this attribute are numbers.
Operational attributes are not returned as a result of an
ldapsearch
operation
unless they are explicitly specified in the search. Generally, operational attributes
are reserved for use by the Directory Server.
Multi If the attribute is multivalued, an X appears in this column, otherwise, this field is
blank. The Directory Server allows more than one instance of a multi-valued
attribute per entry.
