Stephan,
Multimaster uses some mirrormode settings.   (I was confused about that too)

Make sure your database section has at least the following

serverID <number of server>   #e.g. serverID 1, next server is serverID 2, etc; unique per server

syncrepl rid=1 provider=ldap://server2.....   # put on server 1 and server 2
syncrepl rid=2  provider=ldap://server1....   # put on server 1 and server 2 too

mirrormode true
overlay syncprov



Are you sure the replication is working.  If you turn on replication logging (man slapd.conf) via the debug option do you see the replication succeed?    If both servers have the same syncrepl rid=000 then you are missing one RID.  You need a rid to sync from A to B and then a contra one to sync B to A (multi-master).     The URI/provider should swap on the syncrepl lines otherwise the rest should be virtually identical.

Ok I tried it with rid=1 on the one server and rid=1 on the other one and
serverID = 1 and serverID = 2. But I thought that you only need the serverid
stuff for mirrormode.

In the end it doesn't work with this setting either.

Stephan,

With mutlimaster, you still should have the serverID RID like with
mirror-mode.

e.g. something like:         syncrepl      rid=1
as Gavin mentioned.

Hi,
I tried to do a Multimaster Replication the replication works quite
nice, but since I activated it I can't edit my ldap directory. When
ever I try to I get "server is unwilling to perform". It seems as
I'm not authenticated, but I am. I use openldap 2.4.7 in debian
testing.

I don't see any ServerID there?
