Why teams connect Ldap and Materialize

Close the gap between analytics and operations: Materialize holds the record while Ldap runs the day-to-day work, and Stacksync keeps the two in step in real time, in both directions.

Materialize is the central store where teams keep Materialized Views, Sinks, Indexes, Clusters 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 Organizational units (ou), Attributes, Operational attributes, Schema (subschema subentry) produced in Ldap are exactly what analysts want to measure in Materialize, and the curated rows in Materialize 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 Materialized Views, Sinks, Indexes, Clusters in Materialize with Organizational units (ou), Attributes, Operational attributes, Schema (subschema subentry) 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.

Common use cases

  • 01 Maintain real-time inventory, usage, or account-health counters consumed by customer-facing applications.
  • 02 Bridge streaming sources and non-streaming destinations by materializing joins across both.
  • 03 Read person, group, and organizationalUnit entries into a warehouse for periodic access reviews and audit evidence without LDIF exports.
  • 04 Connect a niche or legacy directory server that has no dedicated Stacksync connector but speaks LDAPv3, syncing it over a bind DN and TLS.

Common sync patterns

Operational data lands in Materialize for analytics

Records created in Ldap — issues, events, messages, metrics, or user changes — replicate into Materialize tables as they happen, so reporting runs on current data instead of last night's export.

Warehouse signals reach Ldap

A row scored, flagged, or enriched in Materialize creates or updates the matching record in Ldap, so the operational tool acts on the same data the analysts already see.

Backfill history, then stay live

Load the existing set of Organizational units (ou), Attributes, Operational attributes, Schema (subschema subentry) into Materialize once, then keep it current with every change — you get full history plus real-time updates without a separate pipeline.

What you can sync between Ldap and Materialize

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 Materialize objects How this pairing syncs
Attributes The typed name/value pairs on each entry (cn, mail, memberOf, objectClass); the schema defines which attributes each objectClass allows, and mappings are built per attribute. Indexes In-memory arrangements that make view reads fast for serving workloads. Attributes is specific to Ldap and Indexes to Materialize — each maps to any object or custom field on the other side.
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. Clusters Compute pools that isolate ingestion, view maintenance, and serving. Operational attributes is specific to Ldap and Clusters to Materialize — 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. Connections & Secrets Stored credentials and endpoints used by sources and sinks. Schema (subschema subentry) is specific to Ldap and Connections & Secrets to Materialize — 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 & Databases Namespaces that organize objects a sync targets. Entries is specific to Ldap and Schemas & Databases to Materialize — 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 User-managed tables that accept INSERT/UPDATE/DELETE from sync pipelines. Person entries (inetOrgPerson / user) is specific to Ldap and Tables to Materialize — 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. Sources Ingestion points (Kafka, Postgres CDC, MySQL CDC, webhook) that feed external data into Materialize. Groups (groupOfNames / posixGroup) is specific to Ldap and Sources to Materialize — each maps to any object or custom field on the other side.

How changes propagate between Ldap and Materialize

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.

Ldap Materialize Interval-based propagation

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

Materialize Ldap Sub-second propagation

DetectionChanges in Materialize are captured at the source via change data capture — no polling loop against its API. SUBSCRIBE queries stream row-level changes of any view or table to the client.

DeliveryEach detected change is written to Ldap through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Ldap: LDAP defines no request quota; throughput is bounded by the server's sizelimit and timelimit administrative limits, connection and thread caps, and the CPU/IO it shares with live authentication traffic, so large syncs can contend with production lookups and must page results.

How the Ldap and Materialize connectors work

Ldap

Integration surface
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.
Change detection
No universal native change feed. Incremental sync polls the modifyTimestamp operational attribute (or entryCSN / uSNChanged on servers that expose them) for entries changed since the last cursor; detecting deletes needs a server changelog or tombstones because a plain search cannot see removed entries. Some servers add Persistent Search or RFC 4533 content-sync (syncrepl), but that support is server-specific. No webhooks.
