We have a setup using a JDBC driver and AD driver.

The JDBC publishes into eDirectory, and AD subscribes from edirectory.
This is the flow, no information travels backwards.

If any change is created from the jdbc database flows right through the
system, however if I create a group in edirectory as some groups do not
need to generated directory from the database I find this will not flow
through to AD. Any groups where this used to function nolonger does, with
members not going through.

As I said, if done from the source within the database everything goes
through to edirectory and then AD without a problem.

Does anyone know what this can be?
