I would like to delete all entries under:

ou=Addressbook,dc=mydomain,dc=com

for instance,
cn=user1,ou=Addressbook,dc=mydomain,dc=com
cn=user2,ou=Addressbook,dc=mydomain,dc=com
cn=user3,ou=Addressbook,dc=mydomain,dc=com
etc....

I have tried
ldapdelete -x -W -D <bind dn> "cn=*,ou=Addressbook,dc=mydomain,dc=com"

Any help?
