Connect Version History

In brief

The documentation now states that Select Containers is read-only, clarifies the existing ADSync database error, and lists failures in version 2.6.84.0 plus a Connector Properties crash.

What Entra admins need to know

When using an existing ADSync database, use version TBD or later instead of 2.6.84.0. Be aware that Connector Properties may close unexpectedly until a later fix.

Documentation change

The comparison below shows only the changed extract. Use the full-page view for complete context.

  • Passwordless authentication in the Microsoft Entra Connect setup wizard is now generally available and enabled by default. The Windows Web Account Manager prompt supports passkeys, FIDO2 security keys, and passwords, reuses the signed-in session across Microsoft Entra services, and preserves Seamless Single Sign-On Kerberos key rotation.

  • Cloud configuration cmdlets no longer require an explicit -AADUserName. When you omit the parameter, Microsoft Entra Connect derives a sign-in hint from the connector configuration and opens an interactive sign-in prompt. This behavior applies to Set-ADSyncAADCompanyFeature, Set-ADSyncAADPasswordSyncState, Enable-ADSyncExportDeletionThreshold, Set-ADSyncScheduler, and Set-ADSyncDirSyncConfiguration.
  • The Select Containers dialog in Synchronization Service Manager is now read-only by default. To restore the legacy editable behavior, set the HKLM\SYSTEM\CurrentControlSet\services\ADSync\Parameters\ContainerPickerReadOnly DWORD value to 0.only.
  • The Generic LDAP connector wizard now validates the TLS server certificate chain and server name. Connections that use an untrusted certificate or a certificate whose name doesn't match the configured server are rejected.
  • Updated the bundled SQL Server 2022 LocalDB from version 16.0.4250.1 to 16.0.4262.2.
