RE: 3 database multimaster



I do it as follows:

In Server 1's slapd.conf:
updatedn "cn=Svr1,o=someorg"

# Replication
replica host=Svr2:389
	    binddn="cn=Svr2,o=someorg"
	    bindmethod=simple credentials=passwd
replogfile "C:/ldap/database/rep.log"

replica host=Svr3:389
	    binddn="cn=Svr3,o=someorg"
	    bindmethod=simple credentials=passwd
replogfile "C:/ldap/database/rep.log"

In Server 2's slapd.conf:
updatedn "cn=Svr2,o=someorg"

# Replication
replica host=Svr1:389
	    binddn="cn=Svr1,o=someorg"
	    bindmethod=simple credentials=passwd
replogfile "C:/ldap/database/rep.log"

replica host=Svr3:389
	    binddn="cn=Svr3,o=someorg"
	    bindmethod=simple credentials=passwd
replogfile "C:/ldap/database/rep.log"

In Server 3's slapd.conf:
updatedn "cn=Svr3,o=someorg"

# Replication
replica host=Svr1:389
	    binddn="cn=Svr1,o=someorg"
	    bindmethod=simple credentials=passwd
replogfile "C:/ldap/database/rep.log"

replica host=Svr2:389
	    binddn="cn=Svr2,o=someorg"
	    bindmethod=simple credentials=passwd
replogfile "C:/ldap/database/rep.log"

Hi

Has anyone ever setup a three database multimaster system?

All examples and documentation I've found refer to two system 
multimastering (and there aren't many of them!)

I'm trying to create a system where I have two slaves and one master, 
most changes are made to the master and replicated to the slaves, but 
any updates to the
slaves need to be replicated back to the master and back down to the 
other slave from time to time.

Any suggestions would be much appreciated.

The problem I have here is that you can't have multiple updatedn 
directives in slapd.conf, otherwise I'd use the following.

<slapd.conf.0>
replica host=host1:389
   binddn="cn=REPLICATOR0,o=someorg"
   bindmethod=simple credentials=passwd

replica host=host2:389
   binddn="cn=REPLICATOR0,o=someorg"
   bindmethod=simple credentials=passwd

updatedn cn=REPLICATOR1,o=someorg
updatedn cn=REPLICATOR2,o=someorg
</slapd.conf.0>

<slapd.conf.1>
replica host=host0:389
   binddn="cn=REPLICATOR1,o=someorg"
   bindmethod=simple credentials=passwd

replica host=host2:389
   binddn="cn=REPLICATOR1,o=someorg"
   bindmethod=simple credentials=passwd

updatedn cn=REPLICATOR0,o=someorg
updatedn cn=REPLICATOR2,o=someorg
</slapd.conf.1>

<slapd.conf.2>
replica host=host0:389
   binddn="cn=REPLICATOR2,o=someorg"
   bindmethod=simple credentials=passwd

replica host=host1:389
   binddn="cn=REPLICATOR2,o=someorg"
   bindmethod=simple credentials=passwd

updatedn cn=REPLICATOR0,o=someorg
updatedn cn=REPLICATOR1,o=someorg
</slapd.conf.2>

Cheers
