Why teams connect Azure Active Directory and IBM AS/400

Close the gap between your application data and your directory: IBM AS/400 and Azure Active Directory share users, groups, and access in real time, in both directions.

Azure 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 AS/400 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 Physical files (tables), Logical files (views), Members, Rows / records in IBM AS/400 with Users, Groups, Group memberships, Applications in Azure 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 Expose AS/400 order, inventory, and item master data to modern SaaS tools without rewriting green-screen applications.
  • 02 Use journal-based change capture to replicate IBM i data into a cloud warehouse for reporting.
  • 03 Mirror Applications and Service principals into a database or CMDB to track app ownership and credential expiry.
  • 04 Reconcile Entra ID Users and assignedLicenses with an ITSM or finance database to audit license allocation and reclaim unused seats.

Common sync patterns

Read users and groups as ordinary tables

Users, groups, and their memberships from Azure Active Directory land in IBM AS/400 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 Azure Active Directory and IBM AS/400

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.

Azure Active Directory objects IBM AS/400 objects How this pairing syncs
Applications App registrations under /applications; usually read into a database or CMDB for app ownership and credential-expiry tracking. Journals and journal receivers The change log that enables log-based CDC on journaled files. Applications is specific to Azure Active Directory and Journals and journal receivers to IBM AS/400 — each maps to any object or custom field on the other side.
Service principals /servicePrincipals (enterprise apps) plus appRoleAssignments; read for app inventory and access-posture reporting. Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. Service principals is specific to Azure Active Directory and Data queues to IBM AS/400 — each maps to any object or custom field on the other side.
Directory roles /directoryRoles and roleManagement assignments; read for privileged-access reviews, with role-assignment writes where the granted scopes permit. Libraries The schema-equivalent containers that scope which files a sync reads. Directory roles is specific to Azure Active Directory and Libraries to IBM AS/400 — each maps to any object or custom field on the other side.
Devices /devices registered or joined to the tenant; typically read-only into asset and security databases. Physical files (tables) The Db2 for i tables mapped directly to sync targets. Devices is specific to Azure Active Directory and Physical files (tables) to IBM AS/400 — each maps to any object or custom field on the other side.
Users /users in Microsoft Graph; synced two-way — profile attributes, accountEnabled, and assignedLicenses are read out while provisioning writes (create, update, disable, delete) are pushed back. Logical files (views) Indexed or filtered views over physical files, usable as read sources. Users is specific to Azure Active Directory and Logical files (views) to IBM AS/400 — each maps to any object or custom field on the other side.
Groups /groups covering security and Microsoft 365 groups; created, updated, and deleted through Graph, and read into warehouses for entitlement reporting. Members Sub-partitions of files in legacy applications, flattened or selected during syncs. Groups is specific to Azure Active Directory and Members to IBM AS/400 — each maps to any object or custom field on the other side.

How changes propagate between Azure Active Directory and IBM AS/400

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.

Azure Active Directory IBM AS/400 Sub-second propagation

DetectionAzure Active Directory notifies Stacksync of record changes through webhook events. Microsoft Graph delta query (deltaLink tokens returning only changed users and groups, with @removed deletions) paired with change-notification.

DeliveryEach detected change is applied to IBM AS/400 as a row-level write, with types converted between the two schemas.

IBM AS/400 Azure Active Directory Sub-second propagation

DetectionChanges in IBM AS/400 are captured at the source via change data capture — no polling loop against its API. Journal-based CDC by reading journal receivers on journaled files.

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

Rate-limit considerations

  • Azure Active Directory: Resource-unit throttling: roughly 8,000 ResourceUnits per 10 seconds per app for reads on tenants over 500 users, writes near 3,000 requests per 2.5 minutes; 429 responses include a Retry-After header.
  • IBM AS/400: Bounded by system resources and subsystem configuration rather than an API quota.
