meta backend and bad configuration file

[<francesco.policastro@selex-es.com>]

Hi,

I am running slapd 2.4.33 on RHEL, compiled
from the sources.
I successfully configured meta backend
using old style slapd.conf.
My aim is to browse two Active Directories
in two separate forests (success) and to collect in a new group all users
members of two local groups, one for each domain (not  done yet).
For the latter I read that the dynlist
overlay is what I need and I created a hdb database.
The configuration examples I found for
dynlist are in the cn=config style, so I felt pushed to convert my configuration
(slapd -f slapd.conf -F slapd.d).
I did it, but the results are not as
expected, because slapd starts, but slaptest for the new config issues
an error.

# slaptest -f slapd.conf
51137c4c hdb_monitor_db_open: monitoring
disabled; configure monitor database to enable
config file testing succeeded

# slaptest
51137c5a olcDbURI: value #0: unable
to parse URI #0 in "olcDbURI <protocol>://<server>[:port]/<naming
context>".
51137c5a config error processing olcMetaSub={0}uri,olcDatabase={1}meta,cn=config:
unable to parse URI #0 in "olcDbURI <protocol>://<server>[:port]/<naming
context>"
slaptest: bad configuration file!

I assume, please tell me if I am wrong,
that if you have the new cn=config files, then slapd.conf is not used.
But I remove or rename it slapd does
not start and the error message is  the same as for slaptest.

 olcDbURI: value #0: unable to
parse URI #0 in "olcDbURI <protocol>://<server>[:port]/<naming
context>".
 config error processing olcMetaSub={0}uri,olcDatabase={1}meta,cn=config:
unable to parse URI #0 in "olcDbURI <protocol>://<server>[:port]/<naming
context>"
 slapd stopped.

So I am wondering if the new config
files are even read when slapd starts correctly (i.e. when called with
both "-f" and "-F" flags). I know that one of the new
features of version 2.4.33 is just the cn=config support for meta.

Any ideas?
Thanks in advance,
Francesco
