Thank you William! That is great advice, and thank you for the link to the documentation.

Hi there,

Mark already linked some docs and resources. I realise this is probably
pretty stressful being dropped into some new software and not knowing
what's going on! We have fantastic documentation for the server, but
there is a lot of it, so it's hard to know where to start!

My advice is to take backups first. We provide a rich set of tools for
this, and at least if everything goes wrong, you have something to fall
back on. I recommend db2ldif, but others use db2bak. I like db2ldif as
it creates a human readable text file of the db content which is nice
for inspection also. You can read more here:

https://access.redhat.com/documentation/en-us/red_hat_directory_server/
10/html/administration_guide/populating_directory_databases-

exporting_data

So now that you have this, I'd really recommend trying to setup an
environment in parallel you can test on. Two small vms will suffice. Go
through and setup replication for the latest server version -
replication configuration has not changed a great deal, so the concepts
are still just as valid.

The trick to remember is where things are. In a simple setup you have
the replicated data, and you have some local data in cn=config
(dse.ldif). So if you think of it this way:


   SERVER A                        SERVER B

   cn=config                       cn=config
   cn=replication manager...       cn=replication manager...

[                    Replicated Database                        ]

So content in the backend (like dc=example,dc=com) will be shared, but
the content in cn=config is local to each server.

The complexity comes from replication that an agreement from Server A
to replicate to server B, references things locgal to server B. For
example on server A I might an agreement (this is not syntax correct,
it's a demo)

cn=me_to_server_b,cn=replication,....
objectClass: nsds5replicationagreement
binddn: cn=replication manager

         ^ This means "replication manager ON server b" not the
local one.

Anyway, I hope that gives you some information to help get you moving.
Really do take some backups and know how to restore them, because at
the very least, that's your fallback and security.

I hope you manage to fix it! We are always here if you have more
qustions,
