Since Fedora 36 (389-ds-base 2.1.0) The 389 ldap directory server supports two kinds of underlying database:
- Berkeley Database (bdb)
- Lightning Memory-Mapped Database Manager (lmdb)
Newly created instances are still created with bdb by default while libdb is flagged as [deprecated since Fedora 33](Changes/Libdb deprecated - Fedora Project Wiki), this change is about to create lmdb instances by default

<!-- What is the benefit to the distribution?  Will the software we generate be improved? How will the process of creating Fedora releases be improved?
A step on a way to remove a deprecated piece of software.
 
      Be sure to include the following areas if relevant:
      If this is a major capability update, what has changed?
          For example: This change introduces Python 5 that runs without the Global Interpreter Lock and is fully multithreaded.
      If this is a new functionality, what capabilities does it bring?
          For example: This change allows package upgrades to be performed automatically and rolled-back at will.
      Does this improve some specific package or set of packages?
          For example: This change modifies a package to use a different language stack that reduces install size by removing dependencies.
      Does this improve specific Spins or Editions?
          For example: This change modifies the default install of Fedora Workstation to be more in line with the base install of Fedora Server.
      Does this make the distribution more efficient?
          For example: This change replaces thousands of individual %post scriptlets in packages with one script that runs at the end.
      Is this an improvement to maintainer processes?
          For example: Gating Fedora packages on automatic QA tests will make rawhide more stable and allow changes to be implemented more smoothly.
      Is this an improvement targeted as specific contributors?
          For example: Ensuring that a minimal set of tools required for contribution to Fedora are installed by default eases the onboarding of new contributors.  


    When a Change has multiple benefits, it's better to list them all.

<!-- What happens to systems that have had a previous versions of Fedora installed and are updated to the version containing this change? Will anything require manual configuration or data migration? Will any existing functionality be no longer supported? -->
No impact on upgrade because existing instances still use the previously installed  backend interface.
There should not have any compatibility issue (bug excepted) with the ldap requests but performances may be impacted.
There may be issue with application that explicitly:
- configures 389 directory server instances (like freeipa) because the set of configuration attribute for the backend depends of the underlying  database implementation.
  The unused parameter are ignored so it should not impact the compatibility
  But there is a risk for the new parameters: The "20 Gb" default value for the lmdb database maximum size may not be large enough for the application need.
- monitor 389 directory server backends because the the set of attributes in the monitoring entries also depends of the underlying database implementation.

  • Trademark approval: N/A (not needed for this Change)
  • Alignment with Community Initiatives:

Upgrade/compatibility impact

No impact on upgrade because existing instances still use the previously installed backend interface.

There should not have any compatibility issue (bug excepted) with the ldap requests but performances may be impacted.

There may be issue with application that explicitly:

- configures 389 directory server instances (like freeipa) because the set of configuration attribute for the backend depends of the underlying database implementation. 

 The unused parameter are ignored so it should not impact the compatibility
 But there is a risk for the new parameters: The "20 Gb" default value for the lmdb database maximum size may not be large enough for the application need.

- monitor 389 directory server backends because the the set of attributes in the monitoring entries also depends of the underlying database implementation.

more details about these points are described in [389 Directory Server FAQ - BerkeleyDB backend deprecation](https://www.port389.org/docs/389ds/FAQ/Berkeley-DB-deprecation.html)


How To Test

a COPR project https://copr.fedorainfracloud.org/coprs/g/389ds/389-ds-base-freeipa-tests/

contains the build that can be tested ( F37, F38, F39, rawhide on x86_64 and s390x ) So you can install them by using:

sudo dnf copr enable -y @389ds/389-ds-base-freeipa-tests sudo dnf install 389-ds-base-3.0.0

Then you can create new directory server instances and use them.



User Experience

Dependencies

Mainly freeipa packages:

dnf repoquery --whatrequires 389-ds-base --recursive
