Re: OpenLDAP Updating Schema Definition

I've read that OpenLDAP supports runtime schema modifications but I

OpenLDAP does not support this kind of modification.
That page is half right. OpenLDAP does not allow direct modification of the
subschema subentry. In OpenLDAP 2.3 you can add new schema elements by adding
them under the "cn=schema,cn=config" branch (but you cannot modify existing
schema). In OpenLDAP 2.4 you can add/delete/modify schema using cn=config.
When I try the code
on that page, I run into
Exception in thread "main"
javax.naming.directory.InvalidAttributeValueException: [LDAP: error code

It appears that your request contained invalid data. This check occurs pretty
early, before the server even checks whether you're able to make the change.
Does OpenLDAP allow programmic (hopefully but necessarily Java) schema
changes at runtime?
Yes, but you have to provide valid data first.
