Hey Pierangelo, I just noticed http://www.openldap.org/its/index.cgi?findid=6574 - this looks like it fixes the issue I mentioned in http://www.openldap.org/its/index.cgi?findid=6540? Is that assertion correct?

I checked servers/slapd/back-bdb/cache.c. I see that the fix for ITS#6577 dated July 1 is not available in the release build. I checked out the lates= t sources and did a build and tested. 2) The issue still persists in Windows.

(ITS#6608) ppolicy internal modifications break replication
by mbackes＠symas.com 27 Jul '10

27 Jul '10

Full_Name: Matthew Backes Version: RE24 OS: URL: Submission from: (NULL) (76.88.107.46) The current ppolicy draft standard does not address replication issues, and the resulting implementation has trouble. If frontend-chaining to the master and ppolicy_forward_updates is enabled, invalid binds return success (ITS 6607). If they are disabled, the local changes increase the CSNs in the local copy beyond the contextCSN of the provider, which results in broken replication. (ITS 6606) Possible fixes include: * disallowing shadow contexts the use of ppolicy (probably unpopular) * requiring frontend-chaining once that works * not updating operational attributes at all for ppolicy changes. (allows replicas to diverge on bind failure data but is probably safest)
