[389-users] Demoting Supplier to Dedicated Consumer

[Frank Fossa]

Additional information:

When I restart the demoted instance, the following message appear in the
errors log:

[04/Mar/2010:13:01:10 -0500] - _csngen_parse_state: replica id mismatch;
current id - 65535, replica id in the state - 21
[04/Mar/2010:13:01:10 -0500] NSMMReplicationPlugin -
_replica_init_from_config: failed to create csn generator for replica
(cn=replica,cn=\22<suffixroot>\22,cn=mapping tree,cn=config)
[04/Mar/2010:13:01:10 -0500] NSMMReplicationPlugin - Unable to configure
replica <suffixroot>: failed to create csn generator for replica
(cn=replica,cn=\22<suffixroot>\22,cn=mapping tree,cn=config)

I attempted to roll back my change, returning the consumer back to it's
original supplier state (with same replica ID), to no avail.  The following
message was reported in the errors log:

[04/Mar/2010:13:07:27 -0500] NSMMReplicationPlugin - replica_config_modify:
replica does not exist for <suffixroot>

Looking at the running config and in the dse.ldif, I can see the replica
fine.  Any thoughts on how to recover without having to start from scratch?
