The following example sets up the managerName virtual attribute introduced in the previous section:

  1. Update the schema to define the managerName attribute.

    You can optionally add the attribute to an object class.

    1. In a text editor, create a file with the following schema definition for the attribute. 
      dn: cn=schema 
objectClass: top 
objectClass: ldapSubentry 
objectClass: subschema attributeTypes: ( 1.3.6.1.4.1.32473.3.1.9.4 NAME ‘managerName’ 
  EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.44{256} 
  X-ORIGIN ‘Directory Server Example’ )
    2. Save the file as 98-myschema.ldif in the <server-root>/config/schema folder.
  2. Restart the Directory Server. 
    $ bin/stop-server --restart
  3. To create the virtual attribute, use dsconfig. 
    $ bin/dsconfig create-virtual-attribute \ 
  --name "managerName" \ 
  --type mirror \ 
  --set "description:managerName from manager cn" \ 
  --set enabled:true \
  --set attribute-type:managerName \ 
  --set source-attribute:cn \
  --set source-entry-dn-attribute:manager
  4. To verify the mirror virtual attribute, search for an entry. 
    $ bin/ldapsearch --baseDN dc=example,dc=com "(uid=apeters)"
    Your search results in the following.
    dn: uid=apeters,ou=People,dc=example,dc=com 
... (attributes) ... 
manager: uid=jdoe,ou=People,dc=example,dc=com 
managerName: John Doe
