Re: Multi master replication

Hey buddy, havn't you seen some time around here. I compared your slapd config to one of my own and to this one: https://help.ubuntu.com/9.10/serverguide/C/openldap-server.html (see down at "LDAP Replication") From that point I see you're using the same rid for both servers, so both servers are in the ldap way are the "same" and that's a problem because the both DBs have to be unique even if they hold the same data. Please consider to change the rid on one of your servers and repeat the step to replicate the database. Maybe rid=000 to rid=001. Bye.
