Why teams connect Active Directory and Lemlist

Keep the users, groups, and profile details that Lemlist and Active Directory share consistent in real time, so who can work in Lemlist always matches who your directory in Active Directory says belongs there.

Active Directory is where a company records who its people are: their accounts, the groups and roles they hold, and the attributes attached to each one. Lemlist is where a slice of those same people do their work, as agents, members, or seats, and every one of them needs a matching account with the right access. When a directory and a productivity tool are maintained by hand, someone added, moved, or offboarded in one becomes a stale entry in the other within the hour.

Stacksync syncs Activities, Unsubscribes, Webhooks, Team Members in Lemlist with Groups, Group memberships, Devices, Directory roles in Active Directory bi-directionally and in real time. A user created, renamed, moved between groups, or deactivated in either system updates the matching record in the other within seconds, with field-level mapping and conflict resolution in place of CSV uploads and nightly IT batch jobs.

That matters most at the edges of employment. When both systems agree on who has an account, which groups they belong to, and whether they are still active, granting access on day one and revoking it on the last day stops being a manual checklist that trails the directory.

Common use cases

  • 01 Push enriched leads from a warehouse or list-building workflow into Lemlist campaigns automatically
  • 02 Propagate unsubscribes and bounces back to the CRM and other outreach tools for suppression compliance
  • 03 Keep security-group memberships aligned with application entitlement tables so access reflects the right teams as they change.
  • 04 Read Devices and service principals into a database for identity, asset, and license inventory across the tenant.

Common sync patterns

Keep profile attributes current

A person's name, email, department, manager, or phone number corrected in either system updates the other, so the productivity tool shows the same details the directory holds of record.

Mirror group and role membership

Moving a user between groups or roles in Active Directory updates their team, permission set, or seat in Lemlist, so what someone can do reflects where they sit in the directory.

One record per person

People matched across both systems on email or an external ID stay linked, so every account and action in Lemlist ties back to the right identity in Active Directory.

What you can sync between Active Directory and Lemlist

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 Lemlist objects How this pairing syncs
Group memberships Member and owner links between users and groups; membership add/remove changes are surfaced by delta query. Leads Per-campaign prospect records sync in from enrichment sources and back out with status. Group memberships is specific to Active Directory and Leads to Lemlist — 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. Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines. Devices is specific to Active Directory and Activities to Lemlist — 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. Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. Directory roles is specific to Active Directory and Unsubscribes to Lemlist — 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. Webhooks Hook subscriptions define which activity events are pushed to external endpoints. Service principals & applications is specific to Active Directory and Webhooks to Lemlist — 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. Team Members Sender and seat records map outreach activity to reps in other systems. Organizational units is specific to Active Directory and Team Members to Lemlist — 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. Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. Organizational contacts is specific to Active Directory and Campaigns to Lemlist — each maps to any object or custom field on the other side.

How changes propagate between Active Directory and Lemlist

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

Lemlist Active Directory Sub-second propagation

DetectionLemlist notifies Stacksync of record changes through webhook events. Webhooks on outreach activity events, plus 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.
  • Lemlist: Subject to the platform's API rate limits.

How the Active Directory and Lemlist 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.
