Why teams connect Ldap and MySQL

Keep MySQL and Ldap in step: the rows in your database and the Groups (groupOfNames / posixGroup), Organizational units (ou), Attributes, Operational attributes your engineering tools track stay consistent in real time, in both directions.

MySQL 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 Tables, Views, Columns, Primary and Unique Keys in MySQL with Groups (groupOfNames / posixGroup), Organizational units (ou), Attributes, Operational attributes 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 Expose SaaS objects as MySQL tables so legacy internal tools built on MySQL can read live business data
  • 02 Replicate ERP master data (customers, items, pricing) into the MySQL databases behind storefronts and portals
  • 03 Incrementally sync changed entries by polling modifyTimestamp, keeping a downstream store fresh without dumping the whole directory each cycle.
  • 04 Keep group member and uniqueMember attributes aligned with application entitlement tables so directory access reflects the right teams as they change.

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 MySQL, so provisioning and de-provisioning flow from one source.

Turn rows into the records your tools track

A new or changed row in MySQL 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 MySQL 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 MySQL

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 MySQL 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. Triggers An alternative change-capture mechanism when binlog access is unavailable. Groups (groupOfNames / posixGroup) is specific to Ldap and Triggers to MySQL — 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. Databases (Schemas) Top-level namespaces that scope a sync's reads and writes. Organizational units (ou) is specific to Ldap and Databases (Schemas) to MySQL — 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. Tables The primary sync target; rows map to records in connected systems. Attributes is specific to Ldap and Tables to MySQL — 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. Views Read-side projections used as outbound sync sources. Operational attributes is specific to Ldap and Views to MySQL — 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. Columns Field-level mapping targets with engine-typed values. Schema (subschema subentry) is specific to Ldap and Columns to MySQL — 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. Primary and Unique Keys Match keys for idempotent upserts and conflict handling. Entries is specific to Ldap and Primary and Unique Keys to MySQL — each maps to any object or custom field on the other side.

How changes propagate between Ldap and MySQL

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

MySQL Ldap Sub-second propagation

DetectionChanges in MySQL are captured at the source via change data capture — no polling loop against its API. Database triggers — Stacksync creates deterministic triggers for internal logging and syncing (requires log_bin_trust_function_creators=ON when.

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.
  • MySQL: No API rate limits; throughput is bounded by connection limits and server resources.

How the Ldap and MySQL 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.
