-- objectClass mappings: these may be viewed as structuralObjectClass, the ones that are used to decide how to build an entry
|
|
-- id a unique number identifying the objectClass
|
|
-- name the name of the objectClass; it MUST match the name of an objectClass that is loaded in slapd's schema
|
|
-- keytbl the name of the table that is referenced for the primary key of an entry
|
|
-- keycol the name of the column in "keytbl" that contains the primary key of an entry; the pair "keytbl.keycol" uniquely identifies an entry of objectClass "id"
|
|
-- create_proc a procedure to create the entry
|
|
-- delete_proc a procedure to delete the entry; it takes "keytbl.keycol" of the row to be deleted
|
|
-- expect_return a bitmap that marks whether create_proc (1) and delete_proc (2) return a value or not

-- attributeType mappings: describe how an attributeType for a certain objectClass maps to the SQL data.
|
|
-- id a unique number identifying the attribute
|
|
-- oc_map_id the value of "ldap_oc_mappings.id" that identifies the objectClass this attributeType is defined for
|
|
-- name the name of the attributeType; it MUST match the name of an attributeType that is loaded in slapd's schema
|
|

|
|
-- join_where the expression that defines the condition to select this attribute (the "select ... where <join_where> ..." portion)
|
|
-- add_proc a procedure to insert the attribute; it takes the value of the attribute that is added, and the "keytbl.keycol" of the entry it is associated to
|
|
-- delete_proc a procedure to delete the attribute; it takes the value of the attribute that is added, and the "keytbl.keycol" of the entry it is associated to
|
|
-- param_order a mask that marks if the "keytbl.keycol" value comes before or after the value in add_proc (1) and delete_proc (2)
