I have gotten two boxes setup in multi master and was loading up my test data when I noticed everything isn't being replicated.
In particular the entire ou=idmap tree is being sent, but not recorded. When I put slapd into debug I can see the system receiving the entire tree, but it doesn't seem to be trying to insert it into the database.
After it pulls the data over I get an error
do_syncrep2: cookie=rid=001,sid=002,csn=20080807221724.788347Z#000000#001#000000 do_syncrep2: rid=001 CSN too old, ignoring 20080807221724.788347Z#000000#001#000000 ldap_msgfree
Which is telling me the entry is being flagged as older than it should be for getting transferred over. Slapd is doing the efficient thing and skipping entries that /should/ be on the other system already. My problem is that it isn't on the other system.
I realize that the replication work is done off of the UUID and CSN, but about 30% of my replication test came back with the CSN too old message. I am just sort of wondering, is there a way to have openldap say, "Hey, I realize this CSN is old and everything, but this is a dn on the one of us that isn't on the other." Is there something I can do to bulk update the CSNs (fully expecting downtime and horrid performance as loads of needless replications happen)? From my perspective, I would rather have rather horrid performance and a trustworthy mirror than it run like a dream and not have my trust.
