OpenLDAP ...

Hi
I have leaf (i.e. "cn=A B, o=AAA, c=PL") and this is inetOrgPerson object
class.
This object must have attributes of inetOrgPerson object class as well as
attributes of object of different class (i.e. Person).
How can I do this with back-sql (mssql - I must use OpenLDAP with this
backend). How can I store this information in strucures of LDAP.

Sorry but my english is poor.

For example:
-----------------------
-- ldap_oc_mappings --
-----------------------
insert into ldap_oc_mappings
(id,name,keytbl,keycol,create_proc,delete_proc,exp ect_return)
values (1,'organization','ldap_organization','id',NULL,NU LL,0)

insert into ldap_oc_mappings
(id,name,keytbl,keycol,create_proc,delete_proc,exp ect_return)
values (2,'inetorgperson','persons','ldap_id',NULL,NULL,0 )

insert into ldap_oc_mappings
(id,name,keytbl,keycol,create_proc,delete_proc,exp ect_return)
values (3,'person','persons','ldap_id',NULL,NULL,0)

-------------------------
-- ldap_attr_mappings --
-------------------------
insert into ldap_attr_mappings
(id,oc_map_id,name,sel_expr,from_tbls,join_where,a dd_proc,modify_proc,delete
_proc,param_order,expect_return)
values (1,1,'o','ldap_organization.nazwa','ldap_organizat ion',NULL,NULL,
NULL,NULL,0,0)

insert into ldap_attr_mappings
(id,oc_map_id,name,sel_expr,from_tbls,join_where,a dd_proc,modify_proc,delete
_proc,param_order,expect_return)
values (2,2,'cn','persons.firstname + '' ''+
persons.lastname','persons',NULL,NULL, NULL,NULL,0,0)

insert into ldap_attr_mappings
(id,oc_map_id,name,sel_expr,from_tbls,join_where,a dd_proc,modify_proc,delete
_proc,param_order,expect_return)
values (3,2,'userPassword','persons.password','persons',N ULL,NULL,
NULL,NULL,0,0)

-----------------------
-- ldap_entries --
-----------------------
insert into ldap_entries (id,dn,oc_map_id,parent,keyval) values
(1,'c=pl',1,0,1)
insert into ldap_entries (id,dn,oc_map_id,parent,keyval) values
(2,'o=AAA,c=pl',1,1,2)
insert into ldap_entries (id,dn,oc_map_id,parent,keyval) values (3,'cn=A
B,o=AAA,c=pl',2,2,1)


..... and now 'cn=A B,o=AAA,c=pl' is object of inetOrgPerson class but I want
to do it also object of Person class (oc_map_id for this DN must be equal 2
and 3). How ?
