Full_Name: Rein Tollevik Version: CVS head + rein-serverID.patch OS: linux and solaris URL: ftp://ftp.openldap.org/incoming/rein-syncprov.patch Submission from: (NULL) (81.93.160.250) Submitted by: rein

At startup syncprov searches for any entries with an entryCSN value newer than the newest contextCSN it read from the db and replaces the newest contextCSN value with the newest it finds. But the newest entryCSN could have a different sid field, which would result in the server loosing one valid contextCSN and instead introduce two contexCSNs with the same sid field. It could also introduce a defaulted contextCSN with sid=0, which would never be updated unless there exist a server with that sid, ref my previous ITS.

A patch that fixes this is at the referenced URL. It only updates the contextCSN from entryCSN values matching the serverID of this server.

My initial thought was that all the contextCSNs that has newer entryCSN values with the same sid field should be updated. But I'm afraid that could cause syncrepl to miss some entries if it picks up the updated contextCSN values, as there may be entries from remote servers with entryCSN values newer than the contextCSN received from that server. The exception is delta-syncrepl where a similar update of all the contextCSN values should probably be done at startup. But that belongs in syncrepl.c if needed, as it is requiered whether syncprov is used or not.
