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.

Hello,
Can I know the reason why it is not implemented?
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.
