Description of problem:
Attempts to compact a replication changelog with the dsconf CLI are not working.
The changelog is not compacted.

Version-Release number of selected component (if applicable):

$ cat /etc/redhat-release
Red Hat Enterprise Linux release 8.8 (Ootpa)
$
$ rpm -qa | grep 389-ds
389-ds-base-1.4.3.34-1.module+el8dsrv+18528+22f7779f.x86_64
389-ds-base-libs-1.4.3.34-1.module+el8dsrv+18528+22f7779f.x86_64
$

How reproducible:
Always.

Steps to Reproduce:
1. Run the step #5 documented here:
https://access.redhat.com/documentation/en-us/red_hat_directory_server/11/html/administration_guide/trimming_the_replication_changelog#manually_trimming_changelog

$ date ; dsconf -D "cn=Directory Manager" ldap://localhost:1389 backend compact-db --only-changelog
Thu Oct 19 11:16:57 CEST 2023
Enter password for cn=Directory Manager on ldap://localhost:1389:
Successfully started Database Compaction Task
$

Try without the option "--only-changelog":

$ date ; dsconf -D "cn=Directory Manager" ldap://localhost:1389 backend compact-db
Thu Oct 19 11:18:09 CEST 2023
Enter password for cn=Directory Manager on ldap://localhost:1389:
Successfully started Database Compaction Task
$

2. Check the errors log:

There is no mention about replication changelogs:
==================================
[19/Oct/2023:11:17:04.769616210 +0200] - NOTICE - bdb_compact - Compacting databases ...

==================================

3. Try with the "COMPACT_CL5" task:

$ date ; ldapmodify -x -D "cn=Directory Manager" -W -H ldaps://localhost:1636
Thu Oct 19 11:19:10 CEST 2023
Enter LDAP Password:
dn: cn=replica,cn=dc\3Dexample\2Cdc\3Dcom,cn=mapping tree,cn=config
changetype: modify
replace: nsds5task
nsds5task: COMPACT_CL5

modifying entry "cn=replica,cn=dc\3Dexample\2Cdc\3Dcom,cn=mapping tree,cn=config"

$

Now the replication changelogs are compacted:
==================================
[19/Oct/2023:11:19:23.859362246 +0200] - NOTICE - NSMMReplicationPlugin - changelog program - cl5CompactDBs - compacting replication changelogs...
[19/Oct/2023:11:19:23.867203066 +0200] - NOTICE - NSMMReplicationPlugin - changelog program - cl5CompactDBs - compacting replication changelogs finished.
==================================

Actual results:
Cannot compact replication changelogs with the dsconf tool.

Expected results:
The documented command should work as expected.
