Dear list!
If I have an LDIF backup of a cn=config database, taken with slapcat, how would I use it to bootstrap a new server, for example, in a desaster recovery setting?
I tried it and slapadd required a configuration, but cn=config *is* the configuration and I am trying to restore it. So this is a bit of a chicken and egg problem, isn't it?
Is there an "official" way of doing that?
Regards, Torsten

It looked that way, when we started designing this 4 years ago. But yes, we have a solution.

Exactly the same way as you slapcat'd it. What was the exact command line you used for slapcat?
Hi Howard!

I don't actually understand ... ??
What was the exact command line you used for slapcat?
slapcat -b 'cn=config'
(IIRC)

slapcat -b 'cn=config'
Then try:
slapadd -F <empty/slapd.d/directory> -bcn=config -l <ldiffile>

Slapd, etc. needs an /etc/openldap/slapd.conf file, which contains some root-level (eg bootstrap) configuration. You need to copy this file from the original server to the replacement server, and possibly edit it slightly (depending on how much of a 'clone' you are making, eg stuff like server IP numbers, hostnames, etc.).

Hi Robert!

Well, either an /etc/openldap/slapd.conf file *or* a cn=config database, I guess.
Ok, maybe a possible trick is to have a minimal slapd.conf file which just declares a cn=config database to be able to load it that way.
In that case, a cut & paste example somewhere would come in handy.
But I understand that in OpenLDAP 2.5 they think about doing away with slapd.conf entirely. This would then break your approach again.
Maybe Howard will explain a bit better what he meand by "slapadd the same way you slapcat".
