[389-users] Repair replication

[Chun Tat David Chu]

Hey Herb,

You should refer to the Red Hat Directory Server administration guide for
detail about setting up replication which you can locate in here.
http://docs.redhat.com/docs/en-US/Red_Hat_Directory_Server/

>> 1. How can I find out which system(s) is/are master, consumer, hub, etc?
You should be able to determine the role of the Directory Server for each
system by logging into the LDAP console under
"Configuration->Replication".  The role is either "Single Master", "Hub" or
"Dedicated Consumer".

>> 2. How do I confirm that the systems have the correct credentials for
replication? (I am receiving: "Unable to acquire replica: Permission
denied.")
    a. How can I change the bind dn "cn=replication,cn=config" credentials
on each system to ensure replication will work?
You can do that on the console as well.  Just navigate down the directory
tree and manually reset the password for the replication user account.
There's a possibility that your replication user account's password expired.

>> 3. I assume that upon repairing replication (apparently it has not been
working for several years) the systems will all replicate to the most
recent information.  Correct?
I think that's the tricky part.  Make sure you backup your directory on all
the LDAP first so you have something to roll back.  I *believe* the last
step when setting up replication is initializing the directory and that
will wipe out directory on the other LDAP.  Someone on the list might  be
able to provide a better on this but I am just giving you a heads up that
this can be a complicated process.

Good luck
