Why teams connect Active Directory and Google Cloud Spanner

Close the gap between your application data and your directory: Google Cloud Spanner 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. Google Cloud Spanner 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 Change streams, Views, Databases, Tables in Google Cloud Spanner with Organizational units, Organizational contacts, Users, Groups 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 Consolidate data from a globally distributed Spanner deployment into regional business systems.
  • 02 Push billing or entitlement changes from finance tools into Spanner tables the application reads at runtime.
  • 03 Read Users, Groups, and directoryRole assignments into a warehouse for periodic access reviews and SOC 2 audit evidence.
  • 04 Keep security-group memberships aligned with application entitlement tables so access reflects the right teams as they change.

Common sync patterns

Read users and groups as ordinary tables

Users, groups, and their memberships from Active Directory land in Google Cloud Spanner as rows your application and queries can join, so authorization checks and access reporting run against the database instead of the directory API.

Keep group and role membership aligned

A group or role change made in either system updates the other, so the entitlements an application enforces match what the directory grants.

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.

What you can sync between Active Directory and Google Cloud Spanner

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 Google Cloud Spanner objects How this pairing syncs
Organizational contacts Directory contact objects (orgContact); synced for shared address-book and CRM person records. Tables Relational tables mapped one-to-one to sync targets. Organizational contacts is specific to Active Directory and Tables to Google Cloud Spanner — each maps to any object or custom field on the other side.
Users User accounts in Entra ID and on-prem AD DS; synced two-way to create, update attributes, and enable or disable accounts. Rows The unit of read and write in each sync cycle, keyed by primary key. Users is specific to Active Directory and Rows to Google Cloud Spanner — 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. Interleaved tables Child rows physically co-located with parents; synced as related records. Groups is specific to Active Directory and Interleaved tables to Google Cloud Spanner — 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. Secondary indexes Used to make incremental read queries efficient on non-key columns. Group memberships is specific to Active Directory and Secondary indexes to Google Cloud Spanner — 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. Change streams Capture inserts, updates, and deletes for log-style change data capture. Devices is specific to Active Directory and Change streams to Google Cloud Spanner — 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. Views Read-only projections useful for shaping data before it leaves Spanner. Directory roles is specific to Active Directory and Views to Google Cloud Spanner — each maps to any object or custom field on the other side.

How changes propagate between Active Directory and Google Cloud Spanner

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 Google Cloud Spanner 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 applied to Google Cloud Spanner as a row-level write, with types converted between the two schemas.

Google Cloud Spanner Active Directory Sub-second propagation

DetectionChanges in Google Cloud Spanner are captured at the source via change data capture — no polling loop against its API. Change streams (log-style CDC), or timestamp-based polling queries.

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.
  • Google Cloud Spanner: Throughput is bounded by the instance's provisioned compute capacity rather than a fixed API quota.

How the Active Directory and Google Cloud Spanner 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.
Capabilities
