Hello
I wanted to start a "replicant/backup" server at our site.
Actually we only have one openldap server that serve our LAN and I want to start a slave server in case of master's crash.
I've read documentaion here http://www.openldap.org/doc/admin24/replication.html
But I need some help to choose the best config for our site ( a backup server , that's all )
Thank you
Hi Frank,
for backup reasons, did you think about a read only slave who has all the data of the maybe failed master? When you repaired/replaced the master and have it back online, you would be able to restore them back to the master.

hi frank,
all information to build such a setup are covered in the documentation you mentioned earlier. http://www.openldap.org/doc/admin24/replication.html#Syncrepl
The provider would be your master, the consumer your slave and so on... There're some guides out there who show it in another way, but at last its the same setup.
I for myself setup a mirrormod replication and used this guide: https://help.ubuntu.com/8.10/serverguide/C/openldap-server.html
In a combination of both you should be able to setup a solution for your needs.
Bye.

Hi
Is there any reason to setup just a mirror and not setup a multimaster 2 nodes. If both boxes are always up and in sync why not allow multimaster - then if there is a problem there wouldn't be any thing to do to fail over .
by if there is a problem I mean the machine breaking or becoming unavailable....

And is there any reason to setup multi-master? You can still use mirror during failure, yet you can't write to it. I'd say no big deal. I'd have replied the very same thing to your original question. If mirror is not good enough for you, go for multi-master.
