What Stacksync syncs in Ldap.

These objects sync between Ldap and any connected system, with field-level mapping and conflict resolution. Custom fields are picked up from the live schema where Ldap exposes them.

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.
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.
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.
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.
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.
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.
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.
API surface

How Stacksync connects to Ldap.

The connector runs on Ldap's native API. Stacksync manages authentication, rate limits, retries, and schema changes so your team does not maintain integration code.

Connection
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.
Rate limits
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.

What ships with Ldap

Connect Ldap for flexible, real-time data sync.

Real-time sync, workflow automation, event queues, EDI, and monitoring, for every connection.

Real-time

Two-way sync

Changes in Ldap instantly reflect across connected systems. No stale data, no manual imports.

No-code + pro-code

Workflow automation

Trigger automated workflows whenever Ldap data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.

At scale

Event queues

Handle millions of events per minute without losing a single Ldap record.

Observability

Monitoring

Track your Ldap sync health, view errors, and replay failed events in one click.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions.

Use cases

What teams run on the Ldap connector.

LDAP (Lightweight Directory Access Protocol) is the standard protocol for reading and writing directory data - the lookup layer behind corporate logins, email address books, and app authorization. Owned by IT, identity/access (IAM), and directory-services teams, it fronts servers such as OpenLDAP, Microsoft Active Directory, 389 Directory Server, and Oracle Unified Directory. Those directories hold the person, group, and org-unit entries that gate access to systems, and LDAP is fully read-write, so provisioning and governance workflows both read from and write back to it.

  • IT and IAM administrators
  • Directory services administrators
  • Identity / platform engineering
  • Security and compliance (GRC) teams
  • Backend / integration engineers

  1. 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.

  2. Write user entries and group memberships into an LDAP directory from an HR system of record to drive downstream application access.

  3. Read person, group, and organizationalUnit entries into a warehouse for periodic access reviews and audit evidence without LDIF exports.

  4. Connect a niche or legacy directory server that has no dedicated Stacksync connector but speaks LDAPv3, syncing it over a bind DN and TLS.

  5. Incrementally sync changed entries by polling modifyTimestamp, keeping a downstream store fresh without dumping the whole directory each cycle.

  6. Keep group member and uniqueMember attributes aligned with application entitlement tables so directory access reflects the right teams as they change.

How it works

Set up Ldap in minutes, without APIs.

Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.

  1. 01

    Connect your apps

    Authenticate Ldap with its native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.

    Choose tables

    Pick the Ldap objects to sync — Stacksync auto-detects the schema, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.

FAQ

Ldap connector FAQ

What can I sync with the Ldap connector?

Ldap's core objects — Entries, Person entries (inetOrgPerson / user), Groups (groupOfNames / posixGroup), Organizational units (ou) and custom fields — can sync with any of 302 other systems. Every integration is real-time and bidirectional, with field-level mapping and conflict resolution.

How does Stacksync connect to Ldap?

Via 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., authenticated with 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.. Changes are detected as follows — 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.. Stacksync manages rate limits, retries, and schema changes automatically.

Is the Ldap connector two-way?

Yes. Changes made in Ldap propagate to the connected system and vice versa, in milliseconds. One-way flows are also supported when a direction should stay read-only.

How long does a Ldap integration take to set up?

Most Ldap integrations go live in minutes: authenticate Ldap and the other system, pick objects and fields, and enable the sync. No code and no infrastructure to manage.

Is Ldap data secure in transit?

Stacksync is SOC 2 Type II, ISO 27001, GDPR and HIPAA compliant. Ldap data is encrypted in transit, and a zero-persistent-storage architecture means records are not retained after a sync operation.
