Why teams connect Dynamo DB and Ldap

Keep Dynamo DB and Ldap in step: the rows in your database and the Operational attributes, Schema (subschema subentry), Entries, Person entries (inetOrgPerson / user) your engineering tools track stay consistent in real time, in both directions.

Dynamo DB 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 Global Secondary Indexes, DynamoDB Streams, Global Tables, Tables in Dynamo DB with Operational attributes, Schema (subschema subentry), Entries, Person entries (inetOrgPerson / user) 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 Replace ad-hoc export scripts with continuous sync driven by DynamoDB Streams.
  • 02 Stream item changes from DynamoDB application tables into a Postgres or warehouse copy for SQL analytics.
  • 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

Where Ldap manages users or groups: keep identity aligned

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

Turn rows into the records your tools track

A new or changed row in Dynamo DB 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 Dynamo DB as rows, so tickets, alerts, messages, or identity changes become joinable data your services and reports read directly.

What you can sync between Dynamo DB and Ldap

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.

Dynamo DB objects Ldap objects How this pairing syncs
Attributes Per-item fields, including nested maps and lists, flattened or mapped during sync. 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. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Items Schemaless records keyed by partition (and optional sort) key, mapped to rows or SaaS objects in syncs. 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. Items is specific to Dynamo DB and Entries to Ldap — each maps to any object or custom field on the other side.
Partition and Sort Keys The primary key pair used as the match key for bi-directional sync. 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. Partition and Sort Keys is specific to Dynamo DB and Person entries (inetOrgPerson / user) to Ldap — each maps to any object or custom field on the other side.
Global Secondary Indexes Alternate access paths used when sync queries filter on non-key attributes. 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. Global Secondary Indexes is specific to Dynamo DB and Groups (groupOfNames / posixGroup) to Ldap — each maps to any object or custom field on the other side.
DynamoDB Streams Ordered item-level change records consumed for incremental sync. 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. DynamoDB Streams is specific to Dynamo DB and Organizational units (ou) to Ldap — each maps to any object or custom field on the other side.
Global Tables Multi-region replicas relevant when syncs must read from a specific region. 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. Global Tables is specific to Dynamo DB and Operational attributes to Ldap — each maps to any object or custom field on the other side.

How changes propagate between Dynamo DB and Ldap

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.

Dynamo DB Ldap Sub-second propagation

DetectionChanges in Dynamo DB are captured at the source via change data capture — no polling loop against its API. Item-level change streams via DynamoDB Streams or Kinesis Data Streams integration.

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

Ldap Dynamo DB 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 Dynamo DB as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Dynamo DB: Throughput is governed by the table's provisioned or on-demand capacity mode.
  • 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.

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.
