Why teams connect Active Directory and OpenSearch
Close the gap between your application data and your directory: OpenSearch and Active Directory share users, groups, and access in real time, in both directions.
Active Directory is the system of record for who people are and what they can reach: users, the groups they belong to, and the applications assigned to them. OpenSearch holds the operational data those same people show up in, whether an employee or member table that decides who should have an account at all, a customers list, or the rows an application checks before it authorizes an action. The two describe overlapping users and groups, and when a nightly export or a hand-run script is all that connects them, accounts lag joiners and leavers and the application authorizes against a stale picture of who has access.
Stacksync syncs Documents, Index aliases, Index templates, Ingest pipelines in OpenSearch with Devices, Directory roles, Service principals & applications, Organizational units in Active Directory field by field, in real time, and in both directions. You decide which system owns which fields, with the directory holding credentials and group membership and the database holding the source list of people who should exist at all, and Stacksync keeps every copy consistent, resolving conflicts by rules you set. A person added to a table becomes an account within seconds, a departure disables one just as fast, and the directory's users and groups are always present in your tables as ordinary rows.
Common use cases
- 01 Sync product catalogs from an ERP or database into the indexes that back storefront search.
- 02 Keep Postgres as the source of truth while mirroring rows to OpenSearch for full-text and vector queries.
- 03 Keep security-group memberships aligned with application entitlement tables so access reflects the right teams as they change.
- 04 Read Devices and service principals into a database for identity, asset, and license inventory across the tenant.
Common sync patterns
One profile, kept current
A name, department, email, or manager corrected in either system updates the other, so the profile the directory shows and the data the application reads stop drifting apart.
Provision accounts from the source of truth
When a person is added to the employee, member, or customer table in OpenSearch, Stacksync creates the matching user in Active Directory with the right attributes, so access starts from live data instead of a manual ticket.
Deprovision the moment the record changes
When someone is marked inactive or removed in OpenSearch, the matching account in Active Directory is disabled within seconds, closing the window between a departure and a login that still works.
What you can sync between Active Directory and OpenSearch
Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.
| Active Directory objects | OpenSearch objects | How this pairing syncs | |
|---|---|---|---|
| Users User accounts in Entra ID and on-prem AD DS; synced two-way to create, update attributes, and enable or disable accounts. | Data streams Append-oriented time-series storage for logs and events pushed from source systems | Users is specific to Active Directory and Data streams to OpenSearch — each maps to any object or custom field on the other side. | |
| Groups Security and Microsoft 365 groups; synced two-way including name, type, and owner, with membership tracked separately. | Snapshots Backup artifacts, relevant when reseeding an index from a repository | Groups is specific to Active Directory and Snapshots to OpenSearch — each maps to any object or custom field on the other side. | |
| Group memberships Member and owner links between users and groups; membership add/remove changes are surfaced by delta query. | Indexes The core container; synced records land in indexes with defined mappings | Group memberships is specific to Active Directory and Indexes to OpenSearch — each maps to any object or custom field on the other side. | |
| Devices Registered and joined device objects; typically read into a database for inventory and compliance reporting. | Documents JSON records written via the index and bulk APIs and read via search queries | Devices is specific to Active Directory and Documents to OpenSearch — each maps to any object or custom field on the other side. | |
| Directory roles Admin role assignments (directoryRole); read for access reviews and least-privilege governance. | Index aliases Stable names over rotating indexes, used for zero-downtime reindex during backfills | Directory roles is specific to Active Directory and Index aliases to OpenSearch — each maps to any object or custom field on the other side. | |
| Service principals & applications App registrations and enterprise apps; read-mostly for entitlement and license inventory. | Index templates Mapping and settings presets applied to new indexes a sync creates | Service principals & applications is specific to Active Directory and Index templates to OpenSearch — each maps to any object or custom field on the other side. |
How changes propagate between Active Directory and OpenSearch
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
Active Directory OpenSearch Sub-second propagation
DetectionActive Directory notifies Stacksync of record changes through webhook events. Microsoft Graph delta query (change tracking) for Users and Groups, plus change-notification subscriptions (webhooks) for near-real-time triggers.
DeliveryEach detected change is written to OpenSearch through its API, with automatic retries and rate-limit backoff.
OpenSearch Active Directory Interval-based propagation
DetectionStacksync polls OpenSearch for changes on an incremental schedule, reading only records changed since the previous pass. No native change feed.
DeliveryEach detected change is written to Active Directory through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Active Directory: Graph throttles by resource-unit cost per app per tenant in 10-second windows (about 3,500–8,000 units by tenant size); directory delta tokens expire after ~7 days.
- OpenSearch: Throughput bounded by cluster sizing rather than fixed API quotas.

How the Active Directory and OpenSearch connectors work
Active Directory
- Integration surface
- Microsoft Graph REST API (Entra ID / cloud) and LDAP/LDAPS (on-premises AD DS)
- Authentication
- OAuth 2.0 via the Microsoft identity platform — an app registration with application or delegated permissions (e.g. User.ReadWrite.All, Group.ReadWrite.All) and admin consent; on-prem AD DS uses a bound service account over LDAPS.
- Change detection
- Microsoft Graph delta query (change tracking) for Users and Groups, plus change-notification subscriptions (webhooks) for near-real-time triggers; on-prem AD DS uses the DirSync control and uSNChanged polling.

FAQ
Active Directory and OpenSearch integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Active Directory and OpenSearch: authenticate both systems, choose the objects to sync (such as Active Directory's Users and Groups), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
OpenSearch: Amazon OpenSearch Service domains typically authenticate with IAM request signing, while self-managed clusters use the security plugin's basic auth or certificates. Active Directory: On-premises AD DS has no Graph API and syncs over LDAP/LDAPS using the DirSync control, which needs the DS-Replication-Get-Changes right on the partition. Stacksync's field mapping accounts for these differences between Active Directory and OpenSearch without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Active Directory and OpenSearch records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Active Directory and OpenSearch connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Active Directory–OpenSearch integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Active Directory and OpenSearch. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Active Directory: Microsoft Graph delta query (change tracking) for Users and Groups, plus change-notification subscriptions (webhooks) for near-real-time triggers; on-prem AD DS uses the DirSync control and uSNChanged polling. On OpenSearch: No native change feed; reads rely on queries with scroll or point-in-time polling. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
