Having started to look at the changes required to migrate from a
slapd.conf setup to a cn=config setup, one of things I'm struggling with
is how to load new LDAP schemas into cn=config.

I've seen the guides similar to this one here:
which suggest hacking together a temporary slapd.conf file containing
just the include directives, run slaptest, and then hack the output so
that it can be loaded into cn=config using ldapadd.

His step 1 and 2 were fine. Everything after that is garbage.

1: schemaConvert.conf
include /etc/ldap/schema/core.schema
include /etc/ldap/schema/cosine.schema
include /etc/ldap/schema/nis.schema
include /etc/ldap/schema/inetorgperson.schema
include samba.schema

2: slaptest
mkdir config&&  slaptest -f schemaConvert.conf -F config

3: slapcat

slapcat -F config -n0 -s cn=schema,cn=config

and all of your converted schema will pop out, ready to be slapadd'd or
ldapadd'd anywhere else.

Hi Howard,

Thanks for the response - this makes a bit more sense now. Just to
clarify another point: when you generate schemaConvert.conf, I guess
that you need to include *all* schemas in your current cn=config
matching the existing order, as well as the new one you are trying to add?

Obviously the config file has to be valid; any schema that the ones you're converting depend on must be loaded.

Also that begs another question: what happens if you want to modify an
existing schema, e.g. if I need to hack a schema by hand and reload it
into openldap so that it takes effect? Normally I would change the
schema file on disk, restart slapd and it would just work.

I frankly can't believe that you just asked that question. cn=config is an LDAP database. When you want to change its contents, you use ldapmodify. It takes effect immediately and there is no need to restart the server.
