Why teams connect Active Directory and IBM Informix

Close the gap between your application data and your directory: IBM Informix and Active Directory share users, groups, and access in real time, in both directions.

Active Directory is the system of record for who people are and what they can reach: users, the groups they belong to, and the applications assigned to them. IBM Informix holds the operational data those same people show up in, whether an employee or member table that decides who should have an account at all, a customers list, or the rows an application checks before it authorizes an action. The two describe overlapping users and groups, and when a nightly export or a hand-run script is all that connects them, accounts lag joiners and leavers and the application authorizes against a stale picture of who has access.

Stacksync syncs Stored procedures, Logical logs, Databases, Tables in IBM Informix with Directory roles, Service principals & applications, Organizational units, Organizational contacts in Active Directory field by field, in real time, and in both directions. You decide which system owns which fields, with the directory holding credentials and group membership and the database holding the source list of people who should exist at all, and Stacksync keeps every copy consistent, resolving conflicts by rules you set. A person added to a table becomes an account within seconds, a departure disables one just as fast, and the directory's users and groups are always present in your tables as ordinary rows.

Common use cases

  • 01 Sync sensor and meter readings stored in Informix TimeSeries structures to analytics platforms.
  • 02 Run a two-way sync between an Informix-backed retail or POS application and a CRM so store data reaches go-to-market teams.
  • 03 Two-way sync Users and Groups between Microsoft Entra ID and an HRIS or Postgres so joiners, movers, and leavers provision and deprovision automatically.
  • 04 Read Users, Groups, and directoryRole assignments into a warehouse for periodic access reviews and SOC 2 audit evidence.

Common sync patterns

Read users and groups as ordinary tables

Users, groups, and their memberships from Active Directory land in IBM Informix as rows your application and queries can join, so authorization checks and access reporting run against the database instead of the directory API.

Keep group and role membership aligned

A group or role change made in either system updates the other, so the entitlements an application enforces match what the directory grants.

One profile, kept current

A name, department, email, or manager corrected in either system updates the other, so the profile the directory shows and the data the application reads stop drifting apart.

What you can sync between Active Directory and IBM Informix

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.

Active Directory objects IBM Informix objects How this pairing syncs
Service principals & applications App registrations and enterprise apps; read-mostly for entitlement and license inventory. Databases Top-level containers that scope a sync connection. Service principals & applications is specific to Active Directory and Databases to IBM Informix — each maps to any object or custom field on the other side.
Organizational units On-prem AD DS containers (LDAP organizationalUnit) used to scope which users and groups a sync includes. Tables Relational tables mapped directly to sync targets. Organizational units is specific to Active Directory and Tables to IBM Informix — each maps to any object or custom field on the other side.
Organizational contacts Directory contact objects (orgContact); synced for shared address-book and CRM person records. Rows The unit of read and write, keyed by primary key. Organizational contacts is specific to Active Directory and Rows to IBM Informix — each maps to any object or custom field on the other side.
Users User accounts in Entra ID and on-prem AD DS; synced two-way to create, update attributes, and enable or disable accounts. Views Read-only projections used to shape outbound data. Users is specific to Active Directory and Views to IBM Informix — each maps to any object or custom field on the other side.
Groups Security and Microsoft 365 groups; synced two-way including name, type, and owner, with membership tracked separately. TimeSeries objects Informix's native time-series type, usually exposed to syncs through virtual tables. Groups is specific to Active Directory and TimeSeries objects to IBM Informix — each maps to any object or custom field on the other side.
Group memberships Member and owner links between users and groups; membership add/remove changes are surfaced by delta query. Stored procedures Server-side logic sometimes invoked as part of write paths. Group memberships is specific to Active Directory and Stored procedures to IBM Informix — each maps to any object or custom field on the other side.

How changes propagate between Active Directory and IBM Informix

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.

Active Directory IBM Informix Sub-second propagation

DetectionActive Directory notifies Stacksync of record changes through webhook events. Microsoft Graph delta query (change tracking) for Users and Groups, plus change-notification subscriptions (webhooks) for near-real-time triggers.

DeliveryEach detected change is applied to IBM Informix as a row-level write, with types converted between the two schemas.

IBM Informix Active Directory Sub-second propagation

DetectionChanges in IBM Informix are captured at the source via change data capture — no polling loop against its API. Informix's Change Data Capture API reading committed changes from logical logs.

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

Rate-limit considerations

  • Active Directory: Graph throttles by resource-unit cost per app per tenant in 10-second windows (about 3,500–8,000 units by tenant size); directory delta tokens expire after ~7 days.
  • IBM Informix: Bounded by server resources and session limits rather than an API quota.

How the Active Directory and IBM Informix connectors work

Active Directory

Integration surface
Microsoft Graph REST API (Entra ID / cloud) and LDAP/LDAPS (on-premises AD DS)
Authentication
OAuth 2.0 via the Microsoft identity platform — an app registration with application or delegated permissions (e.g. User.ReadWrite.All, Group.ReadWrite.All) and admin consent; on-prem AD DS uses a bound service account over LDAPS.
Change detection
Microsoft Graph delta query (change tracking) for Users and Groups, plus change-notification subscriptions (webhooks) for near-real-time triggers; on-prem AD DS uses the DirSync control and uSNChanged polling.
Capabilities
read · write · webhooks
Rate limits
Graph throttles by resource-unit cost per app per tenant in 10-second windows (about 3,500–8,000 units by tenant size); directory delta tokens expire after ~7 days.

IBM Informix

Integration surface
SQL over JDBC/ODBC drivers; DRDA connectivity is also supported
