Hi, just to be sure that I'm not wrong : when loading (or deleting) a SchemaObject from a schema, we have three case : - the schema is loaded (on disk) and enabled : the schema object is loaded into the registries and the oidRegistry - the schema is loaded (on disk) and disabled : the schema object is loaded into the oidRegistry, no exception is thrown - the schema is not loaded : we throw an exception When I say 'loaded on disk', that means we have an entry associated with the schema (ou=schema, cn=) must previously exist. Is that ok ? -- -- cordialement, regards, Emmanuel Lécharny www.iktek.com directory.apache.org
