Hi!
Honestly I'm quite afraid of the "space explosion" that seems to be an inherent feature of MDB. 8-( (Maybe that's just because of my bad experience with earlier BtrFS filesystem (that seems to use similar concepts IMHO))
Regards, Ulrich

HI!
This is an important note to those who run OpenLDAP slapd based on openSUSE or SLE packages, especially Tumbleweed:
If you're still using OpenLDAP 2.4 or earlier with back-bdb or back-hdb then migrate to back-mdb now because OpenLDAP 2.5 packages won't support these backends anymore!
Disclaimer:
I'm writing as a package maintainer who only updates package "openldap2" in openSUSE Factory/Tumbleweed. I have no official role in openSUSE project nor SUSE.
Background:
As you might already know OpenLDAP 2.5 builds by default have no more support for backends back-hdb and back-bdb based on Berkeley-DB. Furthermore using Berkeley-DB in general is deprecated.
I've received a request to update the openSUSE package "openldap2" and its sub-packages to OpenLDAP release 2.5.7 also removing back-bdb and back-hdb [1]. I'd love to accept this update request really soon because I also want to have the new features in libldap. So the update will hit openSUSE Tumbleweed really soon.
While this change will *not* affect your deployments based on packages from SLE or openSUSE Leap 15.3 or earlier you should prepare your installation for possible future updates by migrating to back-mdb now.
And always use slapcat to backup your database(s) and practice restoring your databases to be prepared for any desaster.
Ciao, Michael.
