🗣️ Foreword

Thank for taking the time to fill this feature request fully. Without it we may not be able to , and the issue may be closed without resolution.

🙍 Problem Statement

Need a way to inject accesslog with database and overlay configuration.

❔ Possible Solution

To update the slapd.conf.erb template with the necessary sections for the database and overlay configuration.

database mdb
suffix dc=example,dc=com
...
overlay accesslog
logdb cn=accesslog
logops writes
logsuccess TRUE
logpurge 07+00:00 01+00:00

Add accesslog attributes to be able to configure basic accesslog overlay and db configuration.

⤴️ Describe alternatives you've considered

I've tried using server_config_hash option and found out the database load doesn't happen in the proper section/order and slapd.conf file won't verify via slaptest.
