4.6. Modify Operation ... If an equality match filter has not been
defined for an attribute type, clients MUST NOT attempt to delete
individual values of that attribute from an entry using the "delete"
form of a modification, and MUST instead use the "replace" form. ...
OpenLDAP's slapd enforces analogous limitations on add because in
absence of an equality rule there's no way to determine whether a new
value is duplicate or not.
you end up needing to delete all the values of that attribute and add
the new set because in the absence of a matching rule there is no way
to perform a "delete" on a single value; see RFC2251:
