LDAP of course does. (at least for delete-operation) by using ldapmodify you
can remove single key/value pairs by specifying both, the key and the value.
changetype: modify
delete: uniqueMember

-> deletes all of them

changetype: modify
delete: uniqueMember
uniqueMember: <value>

-> deletes only the 'uniqueMember-entry(ies)' with the specified value.

to change, just remove and re-add what you want to change, think that should
work with JNDI too, somehow..
