Why teams connect Active Directory and Plex ERP

Keep the employee, group, and account records that Plex ERP 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. Plex ERP 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 Plex ERP and their account still being active in Active Directory is a real security exposure.

Stacksync syncs Purchase orders, Customers, Suppliers, Shipments in Plex ERP with Organizational contacts, Users, Groups, Group memberships 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 Sync production and inventory data from Plex into a warehouse or Postgres for plant-level analytics.
  • 02 Keep customers, parts, and pricing aligned between Plex and the CRM the sales team uses.
  • 03 Read Devices and service principals into a database for identity, asset, and license inventory across the tenant.
  • 04 Two-way sync Users and Groups between Microsoft Entra ID and an HRIS or Postgres so joiners, movers, and leavers provision and deprovision automatically.

Common sync patterns

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.

Create accounts from new records

A person added in one system gets a matching account or record in the other automatically, so a new hire can be granted access without anyone re-keying their details.

What you can sync between Active Directory and Plex ERP

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 Plex ERP objects How this pairing syncs
Groups Security and Microsoft 365 groups; synced two-way including name, type, and owner, with membership tracked separately. Suppliers Vendor records aligned with procurement and AP tools Groups is specific to Active Directory and Suppliers to Plex ERP — 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. Shipments Outbound logistics records synced to trading partners and tracking systems Group memberships is specific to Active Directory and Shipments to Plex ERP — 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. Quality records Checksheet and inspection data pulled into plant dashboards Devices is specific to Active Directory and Quality records to Plex ERP — each maps to any object or custom field on the other side.
Directory roles Admin role assignments (directoryRole); read for access reviews and least-privilege governance. Parts Item master records shared with CRM, e-commerce, and planning tools Directory roles is specific to Active Directory and Parts to Plex ERP — each maps to any object or custom field on the other side.
Service principals & applications App registrations and enterprise apps; read-mostly for entitlement and license inventory. Inventory On-hand balances and locations replicated for visibility outside the plant system Service principals & applications is specific to Active Directory and Inventory to Plex ERP — 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. Production jobs Shop-floor work records combining ERP and MES data for output reporting Organizational units is specific to Active Directory and Production jobs to Plex ERP — each maps to any object or custom field on the other side.

How changes propagate between Active Directory and Plex ERP

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 Plex ERP 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 Plex ERP through its API, with automatic retries and rate-limit backoff.

Plex ERP Active Directory Interval-based propagation

DetectionStacksync polls Plex ERP for changes on an incremental schedule, reading only records changed since the previous pass. Polling.

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.
  • Plex ERP: Subject to the platform's API rate limits.

How the Active Directory and Plex ERP 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.
