The preferred method for extending the LDAP schema is to use the Domino® LDAP Schema database. Use the Domino Directory to extend the schema only if Notes® or Web users require access to the new schema elements through documents in the directory.

Before you begin

Make sure of the following:

• You are working in a copy of the Domino Directory template (ACMENAMES.NTF for example).
• You have Designer or Manager access in the ACL.

To define an attribute for a new object class you have added to the Domino Directory, add a field to the appropriate subform.

Note: Do not add the fields ListName or ServerName.

Procedure

1. From the Domino Administrator or Notes client, choose the name for the attribute, and then complete these steps to determine whether the attribute is already being used:

a. Open the Domino LDAP Schema database (SCHEMA.NSF) on a server that runs the LDAP service.

b. Select the All Schema Documents -> LDAP Attribute Types view.

c. Do a full-text search for the name of the attribute you plan to define for the object class.

d. Do one of the following:

• If the search returns a document whose LDAP name field contains the name of the attribute for which you searched, use the corresponding value in the Notes mapping field in the Attribute document as the name of the new field.
• If the search does not return a document whose LDAP name field contains the name of the attribute for which you searched, use the name of the attribute for which you searched.

3. Do one of the following:

• To define an attribute for a new auxiliary object class, open the subform for the auxiliary object class -- for example, the subform named building.
• To define an attribute for a new structural object class, open the $xxxInheritableSchema subform for the object class -- for example, the subform $acmePrinterInheritableSchema -- and then select the Mandatory tab if the attribute will be required, or select the Optional tab if the attribute will not be required.

5. Next to the Name property, assign the field a name as described in Step 1.

6. Next to the Type property, choose one of the following data types, and keep Editable selected:

Table 1. Data types

Choose this Domino data type	For this LDAP attribute syntax
Text	Directory string
Date/Time	Generalized time
Number	Integer
Names	Distinguished name

a. Select the field.

b. Select Input Validation in the Objects pane at the end of the subform.

c. Enter the following input validation formula:


@V2If(fieldname = ""; @Failure("fieldname is required"); @Success)

Where fieldname is the name you gave the new field.

For example, if you add the field shoesize and you want to require that all entries include values for the field, enter this formula:

@V2If(shoesize = ""; @Failure("shoesize is required"); @Success)
