-- mappings 

-- 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
--	sel_expr	the expression that is used to select this attribute (the "select <sel_expr> from ..." portion)
--	from_tbls	the expression that defines the table(s) this attribute is taken from (the "select ... from <from_tbls> where ..." portion)
--	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)
--	expect_return	a mask that marks whether add_proc (1) and delete_proc(2) are expected to return a value or not
