Multiple LDAP servers

[graffiti]

Hi,

Can we use multiple LDAP servers and let Zimbra load-balance among them? For example write request will go to one master server and read request load-balance among the rest? Or can we partition our users to pieces and store each of them into one LDAP server as the mailbox server?

We don't support this out-of-the-box, but seems you could try to set this up. Are you worried about performance or redundancy? (or both?)

My concern is all about performance. openLDAP has been the bottleneck in our infrastructure since all our services (mail with qmail-ldap, samba with samba-ldap, ftp with pureftpd-ldap and groupware with egroupware) authenticate users through openLDAP but these services dont have any kind of load-balancing and fail-over mechanism.

What we really want is to run two or more LDAP servers and Zimbra will load-balance among these LDAP servers. We can achieve fail-over ourselves using heartbeat or the Redhat Cluster Suite.

Can you give us hint how to do this? We can hack the code ourselves.

Got it. I passed the code ref to you in the other thread.

Youre so helpful that there is no thread shown up around with this passed code. Are you kidding?
