Why teams connect Active Directory and Amazon RDS

Close the gap between your application data and your directory: Amazon RDS 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. Amazon RDS 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 Columns, Primary and Unique Keys, Read Replicas, Stored Procedures in Amazon RDS with Groups, Group memberships, Devices, Directory roles 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 Mirror SaaS objects into RDS tables so product features can join business data with application data in one query
  • 02 Keep an RDS reporting database hydrated from operational tools without maintaining ETL jobs
  • 03 Read Devices and service principals into a database for identity, asset, and license inventory across the tenant.
  • 04 Two-way sync Users and Groups between Microsoft Entra ID and an HRIS or Postgres so joiners, movers, and leavers provision and deprovision automatically.

Common sync patterns

Provision accounts from the source of truth

When a person is added to the employee, member, or customer table in Amazon RDS, 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 Amazon RDS, the matching account in Active Directory is disabled within seconds, closing the window between a departure and a login that still works.

Read users and groups as ordinary tables

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

What you can sync between Active Directory and Amazon RDS

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 Amazon RDS objects How this pairing syncs
Group memberships Member and owner links between users and groups; membership add/remove changes are surfaced by delta query. Schemas Namespaces within a database used to isolate synced tables. Group memberships is specific to Active Directory and Schemas to Amazon RDS — 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. Tables The core sync target; rows map to records in connected SaaS systems. Devices is specific to Active Directory and Tables to Amazon RDS — 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-side projections exposed to outbound syncs. Directory roles is specific to Active Directory and Views to Amazon RDS — 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. Columns Field-level mapping targets, typed per the underlying engine. Service principals & applications is specific to Active Directory and Columns to Amazon RDS — each maps to any object or custom field on the other side.
Organizational units On-prem AD DS containers (LDAP organizationalUnit) used to scope which users and groups a sync includes. Primary and Unique Keys Match keys for idempotent upserts. Organizational units is specific to Active Directory and Primary and Unique Keys to Amazon RDS — each maps to any object or custom field on the other side.
Organizational contacts Directory contact objects (orgContact); synced for shared address-book and CRM person records. Read Replicas Low-impact read endpoints often used as the source side of a sync. Organizational contacts is specific to Active Directory and Read Replicas to Amazon RDS — each maps to any object or custom field on the other side.

How changes propagate between Active Directory and Amazon RDS

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 Amazon RDS 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 Amazon RDS as a row-level write, with types converted between the two schemas.

Amazon RDS Active Directory Sub-second propagation

DetectionChanges in Amazon RDS are captured at the source via change data capture — no polling loop against its API. Engine-native log-based CDC: MySQL/MariaDB binlog, PostgreSQL logical replication, SQL Server CDC.

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.
  • Amazon RDS: No API rate limits; throughput depends on instance class, storage IOPS, and connection limits.

How the Active Directory and Amazon RDS 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

Amazon RDS

SQL wire protocol of the chosen engine (PostgreSQL, MySQL, MariaDB, SQL Server, Oracle)
Authentication
Database credentials over SSL/TLS, or IAM database authentication on supported engines
