Why teams connect Ldap and Snowflake

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

Snowflake is the central store where teams keep Views, Materialized Views, Streams, Stages 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 Attributes, Operational attributes, Schema (subschema subentry), Entries produced in Ldap are exactly what analysts want to measure in Snowflake, and the curated rows in Snowflake 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 Views, Materialized Views, Streams, Stages in Snowflake with Attributes, Operational attributes, Schema (subschema subentry), Entries 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 Activate modeled Snowflake tables by syncing scores and attributes back into CRM fields sales can act on
  • 02 Keep a customer 360 table aligned with its source systems in both directions instead of one-way reverse ETL
  • 03 Keep group member and uniqueMember attributes aligned with application entitlement tables so directory access reflects the right teams as they change.
  • 04 Two-way sync person and group entries between an LDAP directory (OpenLDAP or AD DS) and an HRIS or Postgres so joiners, movers, and leavers provision and deprovision automatically.

Common sync patterns

Keep user and access records aligned

Where Ldap manages users, directory, or access data, those records stay current in Snowflake — and can be provisioned back from it — so ownership and permissions match across both.

Operational data lands in Snowflake for analytics

Records created in Ldap — issues, events, messages, metrics, or user changes — replicate into Snowflake 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 Snowflake creates or updates the matching record in Ldap, so the operational tool acts on the same data the analysts already see.

What you can sync between Ldap and Snowflake

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 Snowflake objects How this pairing syncs
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. Stages File staging areas used for bulk loads into synced tables. Groups (groupOfNames / posixGroup) is specific to Ldap and Stages to Snowflake — 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. Tasks Scheduled SQL used to transform synced data after it lands. Organizational units (ou) is specific to Ldap and Tasks to Snowflake — each maps to any object or custom field on the other side.
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. VARIANT Columns Semi-structured JSON payloads stored alongside relational columns. Attributes is specific to Ldap and VARIANT Columns to Snowflake — 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. Virtual Warehouses The compute a sync's queries run on, sized independently of storage. Operational attributes is specific to Ldap and Virtual Warehouses to Snowflake — 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 Top-level containers that scope which data a sync can touch. Schema (subschema subentry) is specific to Ldap and Databases to Snowflake — 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 Snowflake — each maps to any object or custom field on the other side.

How changes propagate between Ldap and Snowflake

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

Snowflake Ldap Sub-second propagation

DetectionChanges in Snowflake are captured at the source via change data capture — no polling loop against its API. The setup script grants "create stream" on synced schemas (Snowflake streams), but the docs do not name the change-capture mechanism.

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.
  • Snowflake: No conventional API rate limits; cost and throughput are governed by virtual warehouse size and running time.

How the Ldap and Snowflake 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.
