Hello mr. Pierangelo Masarati,
Thanks for the reply. But, is move subtree
operation (implemented in openldap server side) is a combination of delete subtree
and add right?
Or is it like changing the references
in the dn2id file?
Thanks in advance,
Arunachalam.

Yes.
Basically, it's an operation that is
not atomic in pure LDAP (namely, it
requires more than a write
operation), and thus it could be implemented
in many different ways (I mean:
handling errors and conflicts in many
different ways). So there
should be:
1) a need for it
2) an agreed specification about how
to do it
3) someone who codes it.
I recall seeing some old
specification (e.g.
<draft-armijo-ldap-treedelete>,
expired 2001). A much better approach
would be to use LDAP transactions
(e.g. <draft-zeilenga-ldap-txn>) so
that the operation either fails or
succeeds atomically. In OpenLDAP
there's experimental support for
transactions, but I'm not sure subtree
deletion can be performed right now.
