Installing and configuring LDAP on CentOS 6.2

I am pretty new to linux and am working on migrating and existing LDAP server to a newer OS version, CentOS 6.2. I have managed LDAP using phpldapadmin before so I was shielded from the underworkings of ldap.

The old server is using openldap and I am trying to migrate it to the new server. I have exported a .ldif from the old server, but am having issue installing and configuring ldap on the new server.

I have been looking through the literature and have been confused with what has to be done to get it going.

Can anyone help me in the right direction? basically I want to be able to get the new server to the point where I can restore the ldif file from the old server.

After that I will open up another question regarding replication. I have created a linux cluster and want HA for ldap, I believe that openldap has replication, but I am sure it will not be easy.

After looking through things that may be what I do for LDAP but I still need the cluster for some other services. figure that I will just get LDAP migrated and then look into replication.

replication is how you can get the data to the new one, and then you can go through the process of promoting the new as the master versus the old.

once I have the new ldap server, would I use mirroring through ldap to have it located on two servers?

Possibly,

But I've not looked at mirroring.

have you just used for migration, or have you used some other form of replication such as multi-master or something else?

Unfortunately not recently, the setup was to use a primary master and have slave replicas in the various segments (migration from NIS+ setup to LDAP).

Is time of the essence because the current primary is dying?

Do you have your LDAP using internal DB or mysql?

Thanks, I got it configured in a multimaster configuration and everything is working great.
