By default, whenever the replication mechanism replicates the schema, it sends the entire schema to its consumers. There are two situations where it is not desirable to send the entire schema to consumers:
Modifications to cn=schema using DSCC or from the command-line are limited to the user-defined schema elements, and all of the standard schema are unchanged. If you modify the schema often, sending the large set of unchanged schema elements every time has a performance impact. You might be able to improve replication and server performance by replicating only the user-defined schema elements.
When a master on Directory Server replicates to a consumer on Directory Server 5.1, the schema for the configuration attributes of these versions differ and create conflicts. In this case, you must replicate only the user-defined schema elements.
Directory Server uses the 11rfc2307.ldif schema file. The schema file conforms to RFC 2307.
Versions of Directory Server prior to Directory Server 5.2 use the 10rfc2307.ldif schema file.
You cannot use DSCC to perform this task. Use the command line, as described in this procedure.
