Why teams connect Active Directory and SQL Server
Close the gap between your application data and your directory: SQL Server 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. SQL Server 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, CDC Change Tables, Stored Procedures in SQL Server with Users, Groups, Group memberships, Devices 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 on-premises ERP data held in SQL Server into cloud CRM and support systems
- 02 Feed a cloud warehouse from SQL Server continuously using native CDC instead of SSIS batch jobs
- 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
Provision accounts from the source of truth
When a person is added to the employee, member, or customer table in SQL Server, 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 SQL Server, 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 SQL Server 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 SQL Server
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 | SQL Server objects | How this pairing syncs | |
|---|---|---|---|
| Directory roles Admin role assignments (directoryRole); read for access reviews and least-privilege governance. | CDC Change Tables System-populated tables holding captured inserts, updates, and deletes for consumers. | Directory roles is specific to Active Directory and CDC Change Tables to SQL Server — 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. | Stored Procedures T-SQL logic that can validate or post-process synced rows. | Service principals & applications is specific to Active Directory and Stored Procedures to SQL Server — 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. | Databases Instance-level databases that scope a sync's reads and writes. | Organizational units is specific to Active Directory and Databases to SQL Server — 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. | Schemas Namespaces (dbo and custom) used to organize synced tables. | Organizational contacts is specific to Active Directory and Schemas to SQL Server — 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. | Tables The primary sync target; rows map to records in connected systems. | Users is specific to Active Directory and Tables to SQL Server — 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. | Views Read-side projections used as outbound sync sources. | Groups is specific to Active Directory and Views to SQL Server — each maps to any object or custom field on the other side. |
How changes propagate between Active Directory and SQL Server
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 SQL Server 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 SQL Server as a row-level write, with types converted between the two schemas.
SQL Server Active Directory Sub-second propagation
DetectionChanges in SQL Server are captured at the source via change data capture — no polling loop against its API. SQL Server Native Change Data Capture (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.
- SQL Server: No API rate limits; throughput depends on instance resources, licensing tier, and connection limits.

How the Active Directory and SQL Server 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 SQL Server integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Active Directory and SQL Server: authenticate both systems, choose the objects to sync (such as Active Directory's Directory roles and Service principals & applications), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Common patterns for Active Directory and SQL Server: Provision accounts from the source of truth; Deprovision the moment the record changes; Read users and groups as ordinary tables. When a person is added to the employee, member, or customer table in SQL Server, Stacksync creates the matching user in Active Directory with the right attributes, so access starts from live data instead of a manual ticket.

Active Directory: 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. SQL Server: SQL over the TDS wire protocol (Tabular Data Stream), via ODBC/JDBC/ADO.NET drivers. Authentication: Database credentials entered as a connection string or as parameters (host/user/password) in the Create New Sync page. Stacksync manages authentication, retries, and rate limits on both sides.
-
SQL Server: Change Tracking is a lower-overhead alternative that records which rows changed, but not intermediate values, so it suits net-change syncs. Active Directory: DirectoryRole, servicePrincipal, and device objects are effectively read-only for sync; Users, Groups, and memberships are the writable surface. Stacksync's field mapping accounts for these differences between Active Directory and SQL Server 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 SQL Server 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 SQL Server connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Active Directory–SQL Server integration in-house.
