Hi, I am using iRedmail since the 0.x era and constantly upgraded it until latest 1.7.4. I am using Devuan for a while now and lately tried upgrading from Chiamera (Deb11) to Daedalus (Deb12) which comes with OpenLDAP 2.5 which does not support BerkeleyDB backend anymore but my LDAP config of iRedMail is still BDB.

Is there a way to easily migrate this to MDB or how can I make it work again?

Thanks for any help!

Best, Martin

Should be easy, you can export the BDB with slapcat, create a new storage directory for MDB, modify your config to use MDB instead of BDB, and import the LDIF using slapadd

I can't give you step by step instruction,s ince i didn't use LDAP for a long time and dont have a system to test, but i guess you should be able to get around it

This is correct.

Just a reminder: We didn't test iRedMail on Devuan, you may experience issues and you're on your own.

Thanks for your hints. Unfortunately I am not super familiar with OpenLDAP. Can you give me any hints or tutorials I should look for? I mean sure, it's running on Devuan but on Debian i would have the same issues now. The diff is only "no-systemd" but iRedMail runs just fine otherwise. I don't want to break any ldap config.

Thank you!
