RE: Deleting subtree - server side

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,

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.
