Multimaster replication of cn=config working too well?!


Has anyone experienced problems with the cn=config directory syncing the same change across all nodes and breaking the configuration?

In the past I've had problems where the syncrepl parameters are synced across all nodes, including that node itself, which results in the servers then trying to sync with themselves.

The most recent problem however was that the olcSaslHost value was synced to be one particular server on all 3 nodes. As I was using GSSAPI to do the replication this broke it completely and it meant that I could only bind via GSSAPI to one of the 3 servers.

In the meantime I've set the servers not to syncrepl cn=config but this isn't ideal.

Anyone else on the list had similar problems?

Kind regards,
