When someone joins, moves or leaves in PayFit, you want that change reflected in your on-premise Active Directory without anyone touching it by hand. To connect PayFit to Active Directory, Joinly reads each HR change through the PayFit REST API and applies it to your domain through the Joinly AD Agent — a lightweight connector that runs inside your network. PayFit stays your source of truth; Joinly is the engine that keeps every account in the right OU, accurate and traceable.
Key takeaways
PayFit stays your 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 PayFit collaborator and contract data to the right AD security groups and target OUs, and builds the sAMAccountName, UPN and distinguished name from your own rules.
Resolves multi-contract collaborators and per-company (SIREN/SIRET) structure, so accounts land in the correct OU on the start date and aren’t broken by a second contract.
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 PayFit to Active Directory?
Joinly reads each HR change in PayFit in the cloud, then hands the action to the Joinly AD Agent inside your network, which makes the change in Active Directory. PayFit holds the authoritative collaborator and contract record; the agent is the only component that touches your domain.
Joiner. HR completes the hire in PayFit. Joinly reads the new collaborator and their contract, determines the role from job title, department and company, 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 contract start date.
Mover. When a collaborator changes role, department or company, or a new contract becomes the active one, 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 contract end date, Joinly instructs the agent to disable the AD account and optionally move it to a disabled-users OU. Multiple contracts are taken into account, so an account is only disabled when the last active contract ends.
Example: A retail chain runs PayFit and an on-premise AD across its stores and head office. It hires a store assistant with a start date next Monday, on the retail company (SIRET). Joinly reads the collaborator and contract, and on Monday morning the AD Agent creates the user in the Stores > Region-North OU, sets the sAMAccountName to a unique pattern, and adds the Store-Staff group. When the assistant later moves to a head-office role, 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 PayFit change that an admin works through in Active Directory Users and Computers by hand — creating the object, choosing the OU, building the sAMAccountName, adding groups. A generic HRIS connector rarely writes to on-premise AD at all, so the decisions — and often the whole job — still fall 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 role or company, 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 with multi-contract collaborators it is easy to disable an account while another contract is still active.
Joinly vs. the Entra provisioning agent for AD
Microsoft’s Entra provisioning agent can write to on-premise AD, but PayFit isn’t a native Entra source, so there is no supported PayFit-to-AD path through it. Joinly’s AD Agent reads PayFit directly and writes to your domain. Here’s how the two compare for a PayFit-driven AD setup.
Joinly AD Agent | Entra provisioning agent | |
|---|---|---|
Source | Reads the PayFit API directly (collaborators + contracts) | No native PayFit source; reads Entra / a SCIM app |
OU placement | Rule-based on company / department | Single configured container; limited logic |
Role-to-group mapping | Built in, rule-based | Not available out of the box; manual |
Multi-contract collaborators | Resolves which contract drives the account | Not modelled |
Multi-country (SIREN / SIRET) | Per-company mapping rules across countries | Not applicable |
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 PayFit to Active Directory
A few details decide whether this connection stays reliable at scale.
sAMAccountName uniqueness and length. AD limits the sAMAccountName to 20 characters and it must be unique across the domain. Joinly builds it from your rules with a fallback pattern, so duplicate names never produce a collision or a truncated, unreadable login.
OU placement from company and department. PayFit’s company (SIRET) and department don’t map one-to-one to your OU structure. Joinly builds explicit rules that place each user — and move them on a transfer — into the correct OU.
The contract is the central object. In PayFit a collaborator is tied to one or more contracts, and by default PayFit exposes the last active contract only. Joinly applies explicit rules to pick the contract that should own the AD account, so the object reflects the person’s real current position and not a stale contract.
Multi-contract collaborators. A collaborator can hold more than one active contract. Joinly keeps a single, stable AD object driven by the primary contract, so a second contract adds groups rather than creating a duplicate account.
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 PayFit 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 retail chain with around 1,800 employees across 90 stores and a head office, running PayFit but still living in an on-premise Active Directory for its till, rota and stock systems. Every new store assistant, supervisor or head-office hire starts as a PayFit change that IT processes by hand in AD — creating the object, choosing the store OU, building the login, adding groups. With seasonal peaks and constant store-to-store moves the queue never empties, and new joiners wait until day two or three for their account.
Connect PayFit to Active Directory with Joinly and that work disappears. The Joinly AD Agent creates each user in the right store OU on the start date, builds a unique sAMAccountName, adds the correct security groups, moves people on a transfer and disables accounts on the contract end date with a 30-day grace window — all driven by the HR change in PayFit.
“During the seasonal peak we hire hundreds of people across stores, and AD accounts were always the bottleneck. Now an account is simply ready in the right store OU on day one, moves follow the person, and we can show the auditor which PayFit change created every bit of access.” — Head of IT, retail chain
The outcome this setup is designed for: onboarding drops from days to zero touch, privilege creep from old store 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 PayFit 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 PayFit 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 PayFit integration in the Joinly marketplace
Open the Joinly marketplace and search for the PayFit 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 PayFit integration.
3. Follow the installation wizard
You may be redirected to integrations.joinly.app. Create an account there and enter your PayFit connection details: your PayFit API key (created as an admin in the PayFit integrations hub with the appropriate scopes) and your company_id. All data is encrypted and stored securely.

Enter your PayFit API key and company_id 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 PayFit company and department, and build the sAMAccountName, userPrincipalName, mail, department and manager with Liquid templates.

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 PayFit flows through the agent to AD. Add a threshold workflow that disables the account a set period after the contract 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 termination.
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 PayFit 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 PayFit company and department, and moves the object to a new OU automatically when someone transfers.
How is the sAMAccountName built and kept unique?
From your Liquid template, with the generateUniqueUsername helper falling back to the next pattern on a collision, all within AD’s 20-character limit.
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 PayFit 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.
