You can use DSCC to perform this task. For information, see Directory Service Control Center Interface and the DSCC online help.
Use the ldapdelete command-line utility to delete entries from the directory. This utility binds to the directory server and deletes one or more entries based on their DN. You must provide a bind DN that has permission to delete the specified entries.
You cannot delete an entry that has children. The LDAP protocol forbids the situation where child entries would no longer have a parent. For example, you cannot delete an organizational unit entry unless you have first deleted all entries that belong to the organizational unit.
The following example shows only one entry in the organizational unit. This entry and then its parent entry can be deleted.
$ ldapdelete -h host1 -p 1389 -D cn=admin,cn=Administrators,cn=config -w - Enter bind password: uid=bjensen,ou=People,dc=example,dc=com ou=People,dc=example,dc=com
