WARNING: No dynamic config support for database ldbm

[Tomasz Chmielewski <mangoo@wpkg.org>]

I'm trying to build an OpenLDAP (2.3.18) server and to make it run on an 
"embedded" mipsel/uclibc device running Linux.


After some initial hardships, I was able to build slapd + libs + utils 
etc. successfully.

However, when I run it (slapd -d 5), I can see a warning:

WARNING: No dynamic config support for database ldbm


I was going to use ldbm, and to make the binaries as small as possible.

I used the following ./configure options:

./configure --target=mipsel-linux --host=mipsel-linux 
--build=i386-pc-linux-gnu
--with-yielding_select=no --with-tls=no --with-cyrus-sasl=no 
--enable-slurpd=no --enable-ipv6=no  --enable-overlays=no 
--enable-bdb=no --enable-ldbm=mod --enable-hdb=no --enable-monitor=no 
--enable-relay=no --enable-modules


In slapd.conf I have the ldbm module listed (and the files exists there 
of course):

modulepath      /usr/sbin/openldap/
moduleload      back_ldbm.la


Why does slapd say this "No dynamic config support for database ldbm" 
warning?

When I try to search anything using ldapsearch, it doesn't produce any 
results, and moreover slapd says:

=> ldbm_cache_open( "/etc/openldap/db/dn2id.dbb", 73, 600 )
<= ldbm_cache_open NULL "/etc/openldap/db/dn2id.dbb" errno=2 
reason="unknown")
<= dn2id could not open dn2id.dbb


Has anyone get an explanation for that?
