Why teams connect InterSystems IRIS and Ldap

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

InterSystems IRIS 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 Namespaces, Stored Procedures, Tables, Views in InterSystems IRIS 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 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 reference data consistent between an IRIS-based clinical or financial application and downstream SaaS tools
  • 02 Write enriched or corrected records from SaaS apps back into IRIS tables for on-platform processing
  • 03 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.
  • 04 Write user entries and group memberships into an LDAP directory from an HR system of record to drive downstream application access.

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 InterSystems IRIS, so provisioning and de-provisioning flow from one source.

Turn rows into the records your tools track

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

What you can sync between InterSystems IRIS 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.

InterSystems IRIS objects Ldap objects How this pairing syncs
Globals The underlying multidimensional storage; typically accessed indirectly via SQL or objects in syncs. 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. Globals is specific to InterSystems IRIS and Operational attributes to Ldap — each maps to any object or custom field on the other side.
Namespaces Namespaces partition databases and determine the connection context for integrations. 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. Namespaces is specific to InterSystems IRIS and Schema (subschema subentry) to Ldap — each maps to any object or custom field on the other side.
Stored Procedures Server-side logic callable over SQL supports controlled writes and transformations. 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. Stored Procedures is specific to InterSystems IRIS and Entries to Ldap — each maps to any object or custom field on the other side.
Tables Relational projections of stored data are the primary read/write surface for SQL-based syncs. 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. Tables is specific to InterSystems IRIS and Person entries (inetOrgPerson / user) to Ldap — each maps to any object or custom field on the other side.
Views SQL views expose curated slices of data for outbound replication. 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. Views is specific to InterSystems IRIS and Groups (groupOfNames / posixGroup) to Ldap — each maps to any object or custom field on the other side.
Schemas Schema organization scopes which tables a sync connection can see. 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. Schemas is specific to InterSystems IRIS and Organizational units (ou) to Ldap — each maps to any object or custom field on the other side.

How changes propagate between InterSystems IRIS 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.

InterSystems IRIS Ldap Interval-based propagation

DetectionStacksync polls InterSystems IRIS for changes on an incremental schedule, reading only records changed since the previous pass. Polling (timestamp or query-based).

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

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

Rate-limit considerations

  • InterSystems IRIS: Constrained by database resources rather than published API rate limits.
  • 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.
