Why teams connect Ldap and RavenDB

Keep RavenDB and Ldap in step: the rows in your database and the Organizational units (ou), Attributes, Operational attributes, Schema (subschema subentry) your engineering tools track stay consistent in real time, in both directions.

RavenDB is where your application's durable data lives; Ldap is where engineering and operations teams track the issues, events, messages, or identities that run alongside it. The two overlap constantly, a row should open a ticket, an alert should land as a record, a user in one should exist in the other, but bridging them today means per-tool integration code: auth, webhooks, pagination, rate limits, and retries, built and maintained separately for every tool.

Stacksync syncs Counters, Time series, Data subscriptions, Documents in RavenDB 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 keeps every copy consistent and resolves conflicts by rules you set, so the database and the tooling around it never drift apart.

Common use cases

  • 01 Keep external search indexes or caches current from RavenDB change feeds without custom pollers.
  • 02 Stream RavenDB document changes into Postgres or a warehouse via data subscriptions for SQL analytics.
  • 03 Write user entries and group memberships into an LDAP directory from an HR system of record to drive downstream application access.
  • 04 Read person, group, and organizationalUnit entries into a warehouse for periodic access reviews and audit evidence without LDIF exports.

Common sync patterns

Where Ldap manages users or groups: keep identity aligned

Directory and identity records in Ldap stay matched to the users or owners table in RavenDB, so provisioning and de-provisioning flow from one source.

Turn rows into the records your tools track

A new or changed row in RavenDB creates or updates the matching record in Ldap, whether that is an issue, an event, a message, or a user, so the tool reflects the database without a custom API job.

Land tool activity as queryable rows

Records and events from Ldap arrive in RavenDB as rows, so tickets, alerts, messages, or identity changes become joinable data your services and reports read directly.

What you can sync between Ldap and RavenDB

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 RavenDB 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. Counters Numeric values attached to documents that change independently of the document body Groups (groupOfNames / posixGroup) is specific to Ldap and Counters to RavenDB — 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. Time series Timestamped measurements stored per document, synced for metrics analysis Organizational units (ou) is specific to Ldap and Time series to RavenDB — 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. Data subscriptions Server-side change feeds that push matching documents to consumers Attributes is specific to Ldap and Data subscriptions to RavenDB — 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. Documents JSON records, the primary unit read and written during sync Operational attributes is specific to Ldap and Documents to RavenDB — 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. Collections Groupings of documents by type, mapped to tables in relational targets Schema (subschema subentry) is specific to Ldap and Collections to RavenDB — 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. Indexes Static and auto indexes used to query documents for filtered reads Entries is specific to Ldap and Indexes to RavenDB — each maps to any object or custom field on the other side.

How changes propagate between Ldap and RavenDB

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 RavenDB 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 written to RavenDB through its API, with automatic retries and rate-limit backoff.

RavenDB Ldap Sub-second propagation

DetectionChanges in RavenDB are captured at the source via change data capture — no polling loop against its API. Data subscriptions and the Changes API provide server-pushed change feeds.

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.
  • RavenDB: Throughput bounded by cluster resources rather than API quotas.

How the Ldap and RavenDB 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.
