Two-way sync
Changes in Ldap or MotherDuck instantly reflect in both systems. No stale data, no manual imports.
Keep Ldap and MotherDuck in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
MotherDuck is the central store where teams keep Attached Local DuckDB Databases, Databases, Schemas, Tables for reporting and analysis; Ldap runs the operational side of engineering work — tracking issues, moving messages and events, watching systems, and managing users and access. The two overlap wherever the same operational data matters to both: the Entries, Person entries (inetOrgPerson / user), Groups (groupOfNames / posixGroup), Organizational units (ou) produced in Ldap are exactly what analysts want to measure in MotherDuck, and the curated rows in MotherDuck are what should drive the next action in Ldap. When that overlap is bridged by nightly ETL or hand-written scripts, dashboards lag a day behind reality and the tools that should react to warehouse signals never see them.
Stacksync syncs Attached Local DuckDB Databases, Databases, Schemas, Tables in MotherDuck with Entries, Person entries (inetOrgPerson / user), Groups (groupOfNames / posixGroup), Organizational units (ou) in Ldap field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync matches records on a stable external key, keeps every copy consistent, and resolves conflicts by rules you set — so analytics and operations work from the same current data instead of two drifting copies.
Load the existing set of Entries, Person entries (inetOrgPerson / user), Groups (groupOfNames / posixGroup), Organizational units (ou) into MotherDuck once, then keep it current with every change — you get full history plus real-time updates without a separate pipeline.
New and changed records move field by field the moment they change, replacing scheduled ETL and one-off scripts that fail quietly and leave stale rows behind.
Where both systems track the same entity, a change on either side propagates to the other, ending the manual reconciliation between the operational copy and the warehouse copy.
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.
| Ldap objects | MotherDuck objects | How this pairing syncs | |
|---|---|---|---|
| Operational attributes Server-maintained metadata such as modifyTimestamp, createTimestamp, entryUUID, entryCSN, and uSNChanged; read to drive incremental polling and to key entries stably across syncs. | Attached Local DuckDB Databases Local files attached alongside cloud databases for hybrid queries. | Operational attributes is specific to Ldap and Attached Local DuckDB Databases to MotherDuck — each maps to any object or custom field on the other side. | |
| Schema (subschema subentry) The objectClass and attribute-type definitions the server exposes; read to validate that written attributes exist and are single- or multi-valued as expected. | Databases Cloud-hosted DuckDB databases that scope a sync's reads and writes. | Schema (subschema subentry) is specific to Ldap and Databases to MotherDuck — each maps to any object or custom field on the other side. | |
| Entries The fundamental unit of an LDAP directory, each addressed by a distinguished name (DN) and typed by its objectClass; synced two-way as records, with the DN driving upserts and attribute-level updates. | Schemas Namespaces within a database used to organize synced tables. | Entries is specific to Ldap and Schemas to MotherDuck — each maps to any object or custom field on the other side. | |
| Person entries (inetOrgPerson / user) People held under objectClasses such as inetOrgPerson, person, or Active Directory user; synced two-way to create accounts and update attributes like mail, cn, and telephoneNumber. | Tables The main landing target for synced records and source for analysis. | Person entries (inetOrgPerson / user) is specific to Ldap and Tables to MotherDuck — each maps to any object or custom field on the other side. | |
| Groups (groupOfNames / posixGroup) Group entries whose member or uniqueMember attributes list DNs; synced two-way to add and remove membership as teams and entitlements change. | Views Modeled projections used as outbound sync sources. | Groups (groupOfNames / posixGroup) is specific to Ldap and Views to MotherDuck — each maps to any object or custom field on the other side. | |
| Organizational units (ou) Container entries that structure the DIT and scope which subtree a sync reads or writes; used to limit a sync to a branch such as ou=People,dc=corp,dc=com. | Database Shares Read-only copies of a database shared with other users or teams. | Organizational units (ou) is specific to Ldap and Database Shares to MotherDuck — each maps to any object or custom field on the other side. |
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.
DetectionStacksync polls Ldap for changes on an incremental schedule, reading only records changed since the previous pass. No universal native change feed.
DeliveryEach detected change is applied to MotherDuck as a row-level write, with types converted between the two schemas.
DetectionStacksync polls MotherDuck for changes on an incremental schedule, reading only records changed since the previous pass. Polling.
DeliveryEach detected change is written to Ldap through its API, with automatic retries and rate-limit backoff.

Authenticate Ldap and MotherDuck with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the Ldap and MotherDuck objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between Ldap and MotherDuck: authenticate both systems, choose the objects to sync (such as Ldap's Operational attributes and Schema (subschema subentry)), map fields visually, and changes propagate both ways in milliseconds — no code required.
Ldap: LDAPv3 protocol (RFC 4511) over TCP, typically LDAPS on port 636 or StartTLS on 389; reaches any LDAPv3 directory server - OpenLDAP, Microsoft Active Directory, 389 Directory Server, Oracle Unified Directory, PingDS/ForgeRock, NetIQ eDirectory, Apache Directory. Authentication: A bind DN and password (simple bind), typically over TLS, using a service account with rights to the target subtree. SASL mechanisms - GSSAPI/Kerberos, DIGEST-MD5, or EXTERNAL with a client certificate - are available where the server supports them. MotherDuck: SQL through DuckDB clients and drivers using a MotherDuck (md:) connection. Authentication: Access token created in MotherDuck (Settings > General > Create Token), pasted into Stacksync; database name and schema configurable if not using defaults. Stacksync manages authentication, retries, and rate limits on both sides.
MotherDuck: Databases can be shared with other users as read-only shares, separating producers from consumers. Ldap: LDAP is fully read-write: the protocol defines Add, Modify, Modify DN, and Delete alongside Search, so entries and attributes are provisioned and updated, not only read. Stacksync's field mapping accounts for these differences between Ldap and MotherDuck 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 Ldap and MotherDuck records are not retained after a sync operation.
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Ldap and MotherDuck connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Ldap–MotherDuck integration in-house.
