Do you currently only have a single provider? If so, you have to manually clean up the old contextCSNs by exporting the database, using sed or similar to replace all #001#, #002#, and #004# in the database entryCSN fields with #00a#, delete the existing contextCSN values for other than #00a#, and then reload the DB on all servers. It's been on my to-do to file an ITS that allows one to forcefully reset all serverIDs with slapadd to a single serverID, so I should probably go file that. ;) Regards, Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>
