{i'm sorry if this a duplicated}
i've "successfully" set up replication in a master-slave orientation, with persistent replication; the consumer receives database changes as they are made to the master.
i initialize the consumer database using a ldif created on the provider: *"* *slapcat -b dc=murphy,dc=bz-v -l transfer.ldif" * it has been functional for the past three weeks.for the most part it works, entries are updated immediately. however, twice the data entires within all organizational units have been deleted and about four times either the syncuser or the admin cn's have been deleted from the consumer.
i'm about to start over and entirely reconfigure the consumer. i'd appreciate any feedback on anything that needs adjusting in my configuration or any gotchas. specifically - is my syncrepl directive accurate? - in initial configuration (dpkg) should i setup a different database than the one i intend to replicate?
both consumer and provider are running openldap 2.4.15-1ubuntu3
thanks.
