Quanah - thanks for the response. Sorry to insult if I did - but thank
you, I DID read the admin guide. Which as you have also pointed out uses
slapd.conf examples. Since I am not knee-deep in commercial OpenLdap
configuration every day (I am just a lowly IT admin, not a
paid-to-openldap-person) I would disagree in that your comment that
"conversion to cn=config" process isn't trivial, personally I get quite
swamped by it, but push through as best I can. But if you're offering to
convert my sample configs for me, I'd be happy to share them with you.
You can convert your sample configs via the slaptest command, as documented.
perhaps you could help the community by providing some OLC config
examples for the admin guide, that way us peons would be able to use that
as our only official source instead of having to google to find "Random"
My point was more that converting examples in the admin guide from
slapd.conf to cn=config is fairly trivial.
For example, if we look at section 220.127.116.11 in the admin guide:
index objectclass,entryCSN,entryUUID eq
syncprov-checkpoint 100 10
this is rather trivially converted to:
olcDbIndex: objectClass eq
olcDbIndex: entryUUID eq
olcDbIndex: entryCSN eq
olcSpCheckpoint: 100 10
etc. Converting to cn=config from slapd.conf is not particularly difficult.
I *can* move to refreshAndPersist; but the service provides two
documented options (information I got from reading the admin guide), the
description for refreshOnly best fits my scenario and needs. I didn't
read any reason as to *not* use - perhaps you're aware of a bug report
that refreshOnly is broken?
I'm aware that operating in refreshOnly is problematic, and it is advise
not to use it. If you want to persist in using it, I certainly can't stop
you. ;) If/when I find time to rewrite the admin guide, removing it from
the examples will be one of the first steps I take.
Perhaps my research (which I'm sure isn't as broad as yours) just seemed
to point to the fact that openldap will/may be depreciating the
slapd.conf procedures, and that everyone should get on board with OLC as
soon as possible. While I can perform the setup with slapd.conf (as noted
in the admin guide), I was hoping to practice some useful technique I
could use in the future.
Again, as noted in the documentation, you can set up one time with
slapd.conf, and then move forward with converting it to cn=config via
slaptest, and then just use cn=config from that point forward, using ldap*
commands to make updates as necessary.
If you want some further examples of cn=config, you may like the following:
Which has a basic cn=config layout for a standalone server with a suffix of
"" and a few overlays loaded as a starting point.
You may also be interested in the tools I wrote for manipulating cn=config
to use as examples:
etc. While bits of it are specific to Zimbra, the ideas behind
updating/modifying cn=config are universal.
On the documentation, I would note that it is a community effort, and
anyone can contribute updates, etc, via the ITS system. The sad fact is,
many people complain about the documentation, but very few ever step up and
contribute back, which means that it often languishes.
I hope the above helps.
