I'm not sure I clearly understood the issue; if I have

olcSuffix: dc=foo

dn: olcDatabase={2}bdb,cn=config
olcSuffix: dc=bar

and I want to add

dn: olcDatabase=bdb,cn=config
olcSuffix: dc=foobar

I'd expect:

a) if I don't place any {X}, to become

dn: olcDatabase={3}bdb,cn=config
olcSuffix: dc=foobar

b) otherwise, if I want to make it the first of the list, I'd expect to
need to do something like

dn: olcDatabase={1}bdb,cn=config
olcSuffix: dc=foobar

and see the rest become

dn: olcDatabase={2}bdb,cn=config
olcSuffix: dc=foo

dn: olcDatabase={3}bdb,cn=config
olcSuffix: dc=bar

I've tried both and none seems to work: Am I missing anything?

What you expect is correct, but the rename code has not been implemented. It seemed like a low priority feature at the time and I haven't gotten back to finishing it.

Things like this really call for a hierarchical database config mechanism. Then we could get rid of the clumsy glue/subordinate syntax and just put databases where they're supposed to go, explicitly. Something like:

    dn: olcDatabase={0}frontend,cn=config

    dn: olcDatabase={0}bdb,olcDatabase={0}frontend,cn=config
    olcSuffix: dc=example,dc=com

dn: olcDatabase={0}bdb,olcDatabase={0}bdb,olcDatabase={0}frontend,cn=config
olcSuffix: ou=part1,dc=example,dc=com

dn: olcDatabase={1}bdb,olcDatabase={0}bdb,olcDatabase={0}frontend,cn=config
olcSuffix: ou=part2,dc=example,dc=com

Of course, the above is just ugly.

If we restricted all databases to have a unique single suffix, we could just use the suffix DNs:

    dn: dc=example,dc=com,ou=Databases,cn=config

    dn: ou=part1,dc=example,dc=com,ou=Databases,cn=config

    dn: ou=part2,dc=example,dc=com,ou=Databases,cn=config

dn: cn=deeply nested,ou=container,dc=example,dc=com,ou=Databases,cn=config

I would have preferred this approach originally (we used something similar in Connexitor EMS) but the restrictions are a bit of a problem.

I have the following configuration:

  dn: olcDatabase={2}bdb,cn=config
  olcSuffix: ou=applications,dc=UGent,dc=be

  dn: olcDatabase={3}bdb,cn=config
  olcSuffix: ou=groups,dc=UGent,dc=be

  dn: olcDatabase={4}bdb,cn=config
  olcSuffix: dc=UGent,dc=be

Now I want to add a new database serving a new tree without stopping the

  dn: olcDatabase=bdb,cn=config
  olcSuffix: ou=mail,dc=UGent,dc=be
