MaxValRange[1] #

This value controls the number of values that are returned in the retrieval of multi-valued attributes of an entry.

If an attribute has more than the number of values that are specified by the MaxValRange value, from LDAP, you must use LDAP_SERVER_RANGE_OPTION_OID "Control" to retrieve values that exceed the MaxValRange value.

MaxValueRange controls the number of values that are returned on a single attribute on a single object.
