Re: openldap problem with synchronization

Unfortunately I can't do an update as this is production environment.

What is weird is that if I preform ldapsearch from the external to the internal server (Provider) with exact same properties and are configured in syncrepl configuration I see the updated data correctly, therefore the  problem is not writing access rights or something like that. And the data is correctly updated when Consumer is started after the database of the Consumer is deleted.

Just update to 2.4.38 and read the CHANGES file.
