Why teams connect Active Directory and Infor LN

Keep the employee, group, and account records that Infor LN and Active Directory share aligned in real time, so a person added, moved, or offboarded in one system shows up correctly in the other within seconds.

An ERP and an identity system describe the same workforce from two angles. Infor LN holds the authoritative record of who works at the company, and often their department, title, manager, and cost center. Active Directory controls the accounts, groups, and access those same people use every day. When the two aren't connected, every hire, transfer, and departure has to be keyed twice, and the window between someone leaving in Infor LN and their account still being active in Active Directory is a real security exposure.

Stacksync syncs Service orders, Items, Bills of material, Business partners in Infor LN with Group memberships, Devices, Directory roles, Service principals & applications in Active Directory in real time, with field-level mapping and conflict resolution in place of CSV exports and nightly jobs. A new hire, a department change, or a termination propagates within seconds, and where you want changes to flow both ways — the ERP's org data into the directory, account status back into the ERP — the same mapping handles it.

That matters most at offboarding and audit time. When the directory reflects the ERP's current headcount and org structure, disabling access no longer depends on someone remembering to update a second system, and access reviews start from a roster both sides already agree on.

Common use cases

  • 01 Run a two-way sync of business partners between LN and a CRM so sales and manufacturing share account data.
  • 02 Keep inventory positions aligned between LN and distribution or aftermarket service systems.
  • 03 Read Users, Groups, and directoryRole assignments into a warehouse for periodic access reviews and SOC 2 audit evidence.
  • 04 Keep security-group memberships aligned with application entitlement tables so access reflects the right teams as they change.

Common sync patterns

Keep profile attributes current

A name, email, title, manager, or department corrected in either system updates the other, so directory entries and employee records don't drift apart.

Align group and department membership

When someone changes team or department, their group or organizational-unit membership updates to match, keeping access tied to their current role.

One roster on a shared key

People are matched across both systems on an identifier you choose, such as work email or employee ID, so there is a single accurate list of who is active.

What you can sync between Active Directory and Infor LN

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 Infor LN objects How this pairing syncs
Organizational units On-prem AD DS containers (LDAP organizationalUnit) used to scope which users and groups a sync includes. Production orders Shop-floor work orders synced with MES for execution visibility. Organizational units is specific to Active Directory and Production orders to Infor LN — 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. Warehouse / inventory Stock positions exposed so external channels reflect real availability. Organizational contacts is specific to Active Directory and Warehouse / inventory to Infor LN — 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. Projects Project structures used in engineer-to-order manufacturing scenarios. Users is specific to Active Directory and Projects to Infor LN — 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. Service orders Aftermarket service documents synced with field service tools. Groups is specific to Active Directory and Service orders to Infor LN — 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. Items Manufacturing item masters synced to PLM, MES, and commerce systems. Group memberships is specific to Active Directory and Items to Infor LN — each maps to any object or custom field on the other side.
Devices Registered and joined device objects; typically read into a database for inventory and compliance reporting. Bills of material Product structures shared with engineering and planning tools. Devices is specific to Active Directory and Bills of material to Infor LN — each maps to any object or custom field on the other side.

How changes propagate between Active Directory and Infor LN

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 Infor LN 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 written to Infor LN through its API, with automatic retries and rate-limit backoff.

Infor LN Active Directory Interval-based propagation

DetectionStacksync polls Infor LN for changes on an incremental schedule, reading only records changed since the previous pass. Event-style BOD publications through Infor ION where configured.

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.
  • Infor LN: Subject to the ION API gateway's tenant rate limits in cloud deployments.

How the Active Directory and Infor LN 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.

Infor LN

Integration surface
SOAP and REST web services, with standardized BOD exchange through Infor ION in Infor OS deployments
