Synchronization to server configured with one or more composed attribute plugin instances might be more problematic. It might not be possible to synchronize a composed attribute type if the plugin that generates values for that attribute is configured to prohibit external clients from altering values of that attribute.

If server is used as a sync destination in an environment in which some attribute values might need to be composed, then you should compose those values in the Synchronization Server using a constructed rather than attempt to generate them in the server with the composed attribute plugin.
