Because Sun OpenDS Standard Edition does not store the ECL in a dedicated database, it does not support all the features supported by a JEB back end, such as specific indexes.
In addition, in order to support the changenumber-based ordering that is specified by the LDAP change log draft, Sun OpenDS Standard Edition must store a mapping from the changenumber to the replication state. When the server process a request, it must try to retrieve the replication state from the changenumber that is provided in the request filter. If this cannot be achieved, the request is rejected.
The target entry attributes and the excluded attributes features are not supported.
