When someone joins, moves or leaves in Sesame HR, you want that change reflected in your on-premise Active Directory without anyone touching it by hand. To connect Sesame HR to Active Directory, Joinly reads each HR change through the Sesame HR REST API and applies it to your domain through the Joinly AD Agent — a lightweight connector that runs inside your network. Sesame HR stays your source of truth; Joinly is the engine that keeps every account in the right OU, accurate and traceable.
Key takeaways
Sesame HR 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 Sesame HR departments and offices to the right AD security groups and target OUs, and builds the sAMAccountName, UPN and distinguished name from your own rules.
Because Sesame HR is attendance-first with high seasonal churn, Joinly matches rehires back to the existing AD object and applies robust fallbacks when an org field is missing.
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 Sesame HR to Active Directory?
Joinly reads each HR change in Sesame HR in the cloud through its REST API, then hands the action to the Joinly AD Agent inside your network, which makes the change in Active Directory. Sesame HR holds the authoritative employee record; the agent is the only component that touches your domain.
Joiner. HR completes the hire in Sesame HR. Joinly reads the new record, determines the role from department, office and job title, 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 recorded start date.
Mover. When someone changes department, office or manager, 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 Sesame HR, Joinly instructs the agent to disable the AD account and optionally move it to a disabled-users OU. When a seasonal worker returns, Joinly matches the rehire back to the existing object and re-enables it rather than creating a duplicate.
Example: A private clinic group runs Sesame HR and an on-premise AD across four sites. It hires a receptionist with a start date next Monday. Joinly reads the record, and on Monday morning the AD Agent creates the user in the Site-A > FrontDesk OU, sets the sAMAccountName to a unique pattern, and adds the Reception group. When the receptionist later moves to a different clinic, 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 Sesame HR note that an admin works through in Active Directory Users and Computers by hand — creating the object, choosing the OU, building the sAMAccountName, adding groups. There is no native path from Sesame HR to on-premise AD, so without Joinly this is either fully manual or a custom script someone has to own, and the decisions 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 — painful when a shift worker is expected on site from day one.
Permissions that don’t keep up (privilege creep). When movers change department or office, 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 frequent seasonal turnover it is easy to lose track of who has actually left.
Joinly vs. the Entra provisioning agent for AD
There is no native path from Sesame HR to on-premise AD, so the closest native comparison is stitching the Sesame HR API into Entra’s provisioning agent yourself. It stops short of the part that actually decides access. Here’s how the two compare for a Sesame HR-driven AD setup.
Joinly AD Agent | Entra provisioning agent (custom bridge) | |
|---|---|---|
Source | Reads the Sesame HR REST API directly | Needs a custom SCIM / API bridge you build |
OU placement | Rule-based on department / office | Single configured container; limited logic |
Role-to-group mapping | Built in, rule-based | Not available out of the box; manual |
Sparse / missing org fields | Robust mapping rules with fallbacks | Fails or mis-maps when a field is empty |
Rehire / seasonal staff | Matches back to the existing AD object | Risk of duplicate objects on rehire |
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 Sesame HR 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 departments and offices. Sesame HR departments and offices (work centres) don’t map one-to-one to your OU structure, and records can be sparse. Joinly builds explicit rules — with fallbacks — that place each user, and move them on a transfer, into the correct OU.
Part-time, temporary and seasonal churn. SME workforces here turn over quickly and the same person often returns. Joinly matches a rehire to the existing AD object and re-enables it, so a returning worker keeps their identity instead of getting a fresh, duplicate account.
Attendance data volume. Sesame HR carries a lot of high-volume clock-in and time data alongside identities. Joinly reads only the employee, department and office objects the agent needs on a frequent schedule, so provisioning stays fast and focused.
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 Sesame HR 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 private clinic group with around 1,300 employees across eight sites, running Sesame HR for time tracking and scheduling but still living in an on-premise Active Directory for its clinical and practice systems. Every new receptionist, nurse or support worker starts as a manual job that IT processes by hand in AD — creating the object, choosing the OU, building the login, adding groups. With part-time contracts and frequent moves between sites the queue never empties, and new joiners wait until day two or three for their account. Seasonal returners keep getting brand-new objects, cluttering the directory.
Connect Sesame HR 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 sAMAccountName, adds the correct security groups, moves people on a transfer, matches returning staff back to their existing object, and disables accounts on the end date with a 30-day grace window — all driven by the HR change in Sesame HR.
“An account is simply ready in the right OU when the receptionist walks in, returning staff keep their old login, transfers move themselves, and we can show the auditor exactly which Sesame HR change created every bit of access.” — Head of IT, private clinic group
The outcome this setup is designed for: onboarding drops from days to zero touch, duplicate objects from rehires are eliminated, and the team can walk into its next NIS2 assessment with a complete, source-backed audit trail.
More than a connector
A standalone Sesame HR 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 Sesame HR 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 Sesame HR integration in the Joinly marketplace
Open the Joinly marketplace and search for the Sesame HR 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 Sesame HR integration.
3. Follow the installation wizard
You may be redirected to integrations.joinly.app. Create an account there and enter your Sesame HR connection details: your API token (generated in the Sesame HR admin area) and your region-specific API endpoint. All data is encrypted and stored securely.

Enter your Sesame HR API token and region endpoint 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 department and office, 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 Sesame HR 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 Sesame HR 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 Sesame HR department and office, with fallbacks for sparse records, 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 Sesame HR 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.
