You can use DSCC to perform this task. For information, see Directory Service Control Center Interface and the DSCC online help.
Prepare your object class definition according to the syntax specified in RFC 4517.
Use the ldapmodify(1) command to add your object class definition.
Notice that Directory Server adds X-ORIGIN 'user defined' to the definition that you provide.
The following example adds a new object class using the ldapmodify command:
$ cat blogger.ldif dn: cn=schema changetype: modify add: objectClasses objectClasses: ( 1.2.3.4.5.6.8 NAME 'blogger' DESC 'Someone who has a blog' SUP inetOrgPerson STRUCTURAL MAY blog ) $ ldapmodify -D cn=admin,cn=Administrators,cn=config -w - -f blogger.ldif Enter bind password: modifying entry cn=schema $ |
In a production environment, you would provide a valid, unique OID, not 1.2.3.4.5.6.8.
