When someone joins, moves or leaves in Lessor, you want that change reflected in your on-premise Active Directory without anyone touching it by hand. To connect Lessor to Active Directory, Joinly reads each HR change from your Lessor employee master data in Emply People and applies it to your domain through the Joinly AD Agent — a lightweight connector that runs inside your network. Lessor stays your source of truth; Joinly is the engine that keeps every account in the right OU, accurate and traceable.
Key takeaways
Your Lessor HR record stays the source of truth; Joinly applies every joiner, mover and leaver to on-premise Active Directory automatically.
The Joinly AD Agent runs inside your network and needs only an outbound HTTPS connection — no inbound ports and no domain controller exposed to the internet.
Joinly maps Danish afdeling and stilling to the right AD security groups and target OUs, and builds the sAMAccountName, UPN and distinguished name from your own rules.
The CPR-nummer stays inside Lessor as a matching key only and never becomes a sAMAccountName; Danish characters (æ, ø, å) are transliterated and duplicate names de-duplicated so logins stay valid and unique.
Every action is logged for a complete audit trail, aligned with NIS2 and ISO 27001 — and the same setup extends to a hybrid Entra ID environment.

How does Joinly sync Lessor to Active Directory?
Joinly reads each HR change from your Lessor employee master data in Emply People in the cloud, then hands the action to the Joinly AD Agent inside your network, which makes the change in Active Directory. Lessor holds the authoritative employment record; the agent is the only component that touches your domain.
Joiner. HR registers the new medarbejder in Lessor. Joinly reads the new record, determines the role from afdeling and stilling, and instructs the AD Agent to create the user in the correct OU, build the sAMAccountName and UPN from your rules, and add the right security groups — timed to the registered start date.
Mover. When someone changes stilling or afdeling, Joinly tells the agent to move the user to the matching OU, swap security-group membership and update attributes. Access that no longer fits the new position is removed, so permissions stay aligned with the actual job.
Leaver. On the end date recorded in Lessor, Joinly instructs the agent to disable the AD account and optionally move it to a disabled-users OU, so access ends on the date HR recorded rather than whenever a ticket is processed.
Example: A Danish facility-services company runs Lessor and an on-premise AD across three regions. It registers a new cleaning-team supervisor with a start date next Monday. Joinly reads the record, and on Monday morning the AD Agent creates the user in the Region-Vest > Facility OU, sets the sAMAccountName from a transliterated pattern so the Danish surname resolves cleanly, and adds the Facility-Supervisors group. When the supervisor later moves to another region, the agent moves the object to the new OU and swaps the groups the same day.
What manual AD account management costs
Without automation, every account starts as a message from payroll that an admin works through in Active Directory Users and Computers by hand — creating the object, choosing the OU, building the sAMAccountName, adding groups. Because there is no native Lessor connector to AD, the usual fallback is a generic middleware export or Entra Cloud Sync, which push attributes but offer no role-to-group logic and leave Danish naming and CPR handling to people.
Onboarding delays. New joiners wait for an AD account and group access while a request sits in a queue, losing productive days in their first week.
Permissions that don’t keep up (privilege creep). When movers change stilling or afdeling, old security-group membership often stays attached, so people accumulate rights they no longer need.
Forgotten offboarding. Accounts that aren’t disabled on time are a security and audit risk, and it is easy to lose track of an account once the payroll message has been filed away.
Joinly vs. the Entra provisioning agent for AD
There is no native Lessor connector to on-premise AD, so the usual path is Entra Cloud Sync or a generic middleware export writing to AD. That stops short of the part that actually decides access. Here’s how the two compare for a Lessor-driven AD setup.
Joinly AD Agent | Entra Cloud Sync / generic middleware | |
|---|---|---|
Source | Reads Lessor / Emply People data directly | Reads a generic export or the synced directory |
OU placement | Rule-based on afdeling and stilling | Single configured container; limited logic |
Role-to-group mapping | Built in, rule-based | Not available out of the box; manual |
Future-dated hires | Times creation to the recorded start date | Usually created on import, not on the start date |
Danish data (CPR, æ/ø/å) | CPR excluded, names transliterated and de-duplicated | Left to manual configuration |
sAMAccountName / UPN rules | Custom transformation with uniqueness fallback | Limited expression mapping |
Audit trail | Per-action logging tied to the HR source | Limited |
Watch-outs when connecting Lessor to Active Directory
A few Lessor-specific details decide whether this connection stays reliable and compliant at scale.
sAMAccountName uniqueness and length. AD limits the sAMAccountName to 20 characters and it must be unique across the domain — and Danish names with æ, ø, å plus common surnames make collisions likely. Joinly transliterates and builds the name from your rules with a fallback pattern, so duplicates never produce a collision or a truncated, unreadable login.
OU placement from afdeling and stilling. Danish department and position structures don’t map one-to-one to your OU tree. Joinly builds explicit rules that place each user — and move them on a transfer — into the correct OU.
CPR-nummer is sensitive data. The Danish CPR-nummer must never become a sAMAccountName, UPN or group name. Joinly keeps CPR inside Lessor as a matching key only and builds AD attributes from name and organisation data instead.
Where the identity data lives. LessorLøn and Lessor5 are payroll-first; the identity-usable attributes generally sit in Emply People. Joinly reads from the right source, so AD reflects the HR record rather than the payroll run.
Service-account permissions. The agent acts under a service account with delegated rights. Joinly works with least-privilege delegation scoped to the target OUs, so the agent can create, move and disable users without domain-admin rights.
Joinly handles each of these by default with custom mapping and transformation.
Always audit-ready
Every account action the Joinly AD Agent performs is logged in the Joinly cloud: who was affected, when it happened, which OU and groups changed and which Lessor change triggered it. For NIS2 that matters directly: access can be traced back to an authorised HR source rather than an ad-hoc request. Joinly is ISO 27001 certified, runs in an EU data centre in Amsterdam, applies least-privilege by default, and is built to meet NIS2 and ISO 27001.
Example case
Take a Danish facility-services company with around 1,800 employees across cleaning, catering and maintenance teams at dozens of client sites, running Lessor for payroll and Emply People as its HR core but still living in an on-premise Active Directory for its scheduling and access systems. Every new supervisor, coordinator or office worker starts as a payroll registration that IT then processes by hand in AD — creating the object, choosing the OU, building the login, adding groups. With high turnover and constant transfers between regions the queue never empties, and Danish surnames regularly break the login pattern.
Connect Lessor to Active Directory with Joinly and that work disappears. The Joinly AD Agent creates each user in the right OU on the start date, builds a unique transliterated sAMAccountName, adds the correct security groups, moves people on a transfer and disables accounts on the end date with a 30-day grace window — all driven by the HR change in Lessor, with the CPR-nummer kept safely inside the HR source.
“With our turnover the AD queue was never empty, and Danish names kept breaking the login rule. Now an account is simply ready in the right OU when someone starts, the name always resolves cleanly, and we can show the auditor exactly which Lessor change created every bit of access.” — Head of IT, facility-services provider
The outcome this setup is designed for: onboarding drops from days to zero touch, privilege creep from old roles is eliminated, and the team can walk into its next NIS2 assessment with a complete, source-backed audit trail.
More than a connector
A standalone Lessor to Active Directory connection is a good start, but identity rarely stops at one target. The same Joinly setup extends to Entra ID for a hybrid environment and to your other systems, managing the complete chain from joiner to leaver with logging and governance built in. You review the exceptions; Joinly maintains the chain.

Installation guide
Follow these steps to connect Lessor to your on-premise Active Directory with Joinly. Most of the setup happens in the cloud platform; the only local component is the lightweight Joinly AD Agent, which you install on a domain-joined server.
1. Create your account
Go to platform.joinly.app and create your account.
Note: charges may apply for using the platform after the trial period ends.

Sign up at platform.joinly.app to get started.
2. Find the Lessor integration in the Joinly marketplace
Open the Joinly marketplace and search for the Lessor integration.
Don’t see your system listed? Get in touch at support@koppelhet.nl and we’ll help you out.

Search the marketplace for the Lessor integration.
3. Follow the installation wizard
You may be redirected to integrations.joinly.app. Create an account there and enter your Lessor connection details: the Emply People API endpoint (api.emply.com) and the API key you generate in the Emply platform under API. All data is encrypted and stored securely.

Enter your Lessor / Emply People API endpoint and API key in the wizard.
4. Download the Joinly AD Agent
In the platform, go to Workflows → Select a workflow → Add action → Select ‘Provisioning via Agent’ and download the installer. The agent is a lightweight Windows service that connects your domain to the Joinly cloud over an outbound HTTPS connection only — there are no inbound ports to open.

Download the Joinly AD Agent installer from the provisioning settings.
5. Install the agent on a domain-joined server
Run the installer on a domain-joined Windows server that can reach a domain controller. The server needs outbound HTTPS (port 443) to the Joinly cloud and a GMSA account installation on your domain controller. Run through the installer; it registers the agent as a Windows service that starts automatically.
6. Pair the agent with your Joinly tenant
Copy the pairing token from Settings → Provisioning → AD Agent in the platform and paste it into the agent’s configuration screen. The agent uses the token to register securely with your tenant; once paired, its status shows as Connected in the platform.

Pair the agent with your tenant using the pairing token.
7. Set the target OU and attribute mapping
Configure where users are created and how their attributes are built. Map the distinguished name / OU from afdeling and stilling, and build the sAMAccountName, userPrincipalName, mail, department and manager with Liquid templates — including a transliteration step for Danish characters and a rule that keeps the CPR-nummer out of the directory.

Select the OU and attribute mapping.
8. Configure your workflows
Create an onboarding (joiner) and offboarding (leaver) workflow with trigger-based execution, then an Identity updated workflow with a Create/update employee in Active Directory action so every change in Lessor flows through the agent to AD. Add a threshold workflow that disables the account a set period after the end date (for example 30 days), optionally moving it to a disabled-users OU.

Create a trigger-based onboarding workflow.

A date-threshold workflow disables accounts a set number of days after the end date.
9. Network and firewall requirements
The agent needs outbound HTTPS (443) to the Joinly cloud and a GMSA account with PowerShell access to your domain controllers. No inbound firewall rules are required, and no domain controller is exposed to the internet. For high availability you can run the agent on more than one server.
Need cloud Entra ID provisioning as well? See our guide on connecting Lessor to Microsoft Entra ID, or contact support at support@koppelhet.nl.
Frequently asked questions
Does the Joinly AD Agent need inbound firewall openings?
No. The agent only makes an outbound HTTPS connection to the Joinly cloud and acts on your domain controllers from inside the network through a GMSA with PowerShell access. There are no inbound ports to open and no domain controller is exposed to the internet.
What account does the agent run under?
A Group Managed Service Account (GMSA) with PowerShell access to your domain controllers, scoped to the target OUs so it can create, move and disable user objects without domain-admin rights.
Which OU do new accounts land in?
The one your rules define. Joinly builds the distinguished name and OU placement from Lessor afdeling and stilling, and moves the object to a new OU automatically when someone transfers.
How is the sAMAccountName built and kept unique with Danish names?
From your Liquid template with a transliteration step for æ, ø and å, and the generateUniqueUsername helper falling back to the next pattern on a collision, all within AD’s 20-character limit. The CPR-nummer is never used in the login.
Can I provision to both Active Directory and Entra ID?
Yes. The same Joinly setup drives a hybrid environment — the AD Agent for on-premise AD and the native Entra connection for the cloud. See the Lessor to Entra ID guide.
Can I run more than one agent for high availability?
Yes. You can install the agent on multiple domain-joined servers so provisioning continues if one server is unavailable.
