Affected: >= 2.0.1 and < 2.2.1 · >= 7.x-1.0 and <= 7.x-1.21 · >= 8.x-1.0 and <= 8.x-1.34

Fixed in: 2.2.1

Safe to downgrade to: a release before 2.0.1

1. Check installed version

apt-cache policy ldap--active-directory-integration || rpm -q ldap--active-directory-integration || ldap--active-directory-integration --version

2. UPGRADE to 2.2.1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade ldap--active-directory-integration

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade ldap--active-directory-integration

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 2.0.1 (Debian / Ubuntu)

apt-cache madison ldap--active-directory-integration sudo apt install ldap--active-directory-integration=<VERSION_BEFORE_2.0.1> sudo apt-mark hold ldap--active-directory-integration

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list ldap--active-directory-integration sudo dnf downgrade ldap--active-directory-integration-<VERSION_BEFORE_2.0.1> sudo dnf versionlock add ldap--active-directory-integration

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
