Yes, indeed this is our case. I had to manually slapindex, then only we got the correct result (even though we have specified the attribute to index automatically in slapd.conf).

However, do we have to slapindex nightly since this is a case, or is this a bug (we're using openldap 2.4.19)?

Thanks.

Hi all,

We have a little bit of a problem here. When we tried to search in openldap with the following filter:-

(&(uid=user1)(customAttribute=somevalue))

... it returned no results. But when we use a similar filter, with an asterisk (*) appended for the 2nd attribute:-

(&(uid=user1)(customAttribute=somevalue*))

We got the result just fine. The funny thing is, the result listed customAttribute value as just 'somevalue'. We were wondering what's the extra character that's preventing us from getting the result when using the filter without the asterisk.

Have anyone encountered similar problem before?

All those that change indexes without reindexing the database (man slapindex(8) for details) experience a similar behavior. Could it be your case?

How do you specify automatic attribute indexing in slapd.conf? I didn't know about that.

We have this line in slapd.conf.

index customAttribute pres,eq

Is this not automatic indexing? Or is it just specifying which attribute to index when running slapindex?

Apparently, you ran slapindex without even reading the man page. It *must* be run when you change indexes in slapd.conf, and only in that case. And slapd *must not* be running when you run slapindex (it complains and refuses to start, otherwise, as far as I know).

Or, if you modify indexes using ldapmodify in cn=config, re-indexing will be automatical, no need to run slapindex. Is this what you meant?

I think so. That means, doing ldapmodify when ldap is running live will automatically re-index the attribute?

Thanks for the help!

man slapd.conf(5):

(about index settings) ... Note: Indexing support depends on the particular backend in use. Also, changing these settings will generally require deleting any indices that depend on these parameters and recreating them with slapindex(8). ...

man slapd-bdb(5):

(about the index directive) ... Note: changing index settings in slapd.conf(5) requires rebuilding indices, see slapindex(8); changing index settings dynamically by LDAPModifying "cn=config" automatically causes rebuilding of the indices online in a back- ground task.

Could it be any clearer?
