When someone joins, moves or leaves in isolved, you want that change reflected in your on-premise Active Directory without anyone touching it by hand. To connect isolved to Active Directory, Joinly reads each HR change in isolved People Cloud through the REST API and applies it to your domain through the Joinly AD Agent — a lightweight connector that runs inside your network. isolved stays your source of truth; Joinly is the engine that keeps every account in the right OU, accurate and traceable.
Key takeaways
isolved People Cloud 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 isolved structures — legal company, department, job and work location — to the right AD security groups and target OUs, and builds the sAMAccountName, UPN and distinguished name from your own rules.
Reads the isolved hire date and resolves multi-company clients, so accounts land in the correct OU on the start date and a move between legal companies stays one identity instead of a duplicate.
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 isolved to Active Directory?
Joinly reads each HR change in isolved People Cloud in the cloud, then hands the action to the Joinly AD Agent inside your network, which makes the change in Active Directory. isolved holds the authoritative employment and payroll record; the agent is the only component that touches your domain.
Joiner. HR or the service bureau completes the hire in isolved. Joinly reads the new record, determines the role from legal company, department, job and work location, 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 isolved hire date.
Mover. When someone changes department, job, work location or legal company, 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. When the isolved status moves to Terminated on the recorded termination date, Joinly instructs the agent to disable the AD account and optionally move it to a disabled-users OU. A rehire or status reversal is recognised, so the account reactivates rather than a duplicate being created.
Example: A regional logistics SMB runs isolved People Cloud and an on-premise AD across three depots. It hires a dispatch clerk with a start date next Monday. Joinly reads the hire record, and on Monday morning the AD Agent creates the user in the Depot-North > Dispatch OU, sets the sAMAccountName to a unique pattern, and adds the Dispatch-Operations group. When the clerk later moves to a second legal company in the same isolved client, the agent keeps one object, moves it to the new OU and swaps the groups the same day.
What manual AD account management costs
Without automation, every account starts as an isolved request that an admin works through in Active Directory Users and Computers by hand — creating the object, choosing the OU, building the sAMAccountName, adding groups. Marketplace IGA connectors can push isolved data toward AD, but they offer limited mapping, no role-to-group logic and don’t reason about multi-company clients or pay-driven statuses, so 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.
Permissions that don’t keep up (privilege creep). When movers change department, job or legal 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 payroll-driven statuses a Terminated flag can flip back on a rehire or pay correction, so timing matters.
Joinly vs. a marketplace connector for AD
An isolved Marketplace IGA connector can write isolved data to on-premise AD, but it stops short of the part that actually decides access. Here’s how the two compare for an isolved People Cloud-driven AD setup.
Joinly AD Agent | Marketplace connector (isolved → AD) | |
|---|---|---|
Source | Reads the isolved REST API directly | Reads isolved directly |
OU placement | Rule-based on legal company, department and work location | Single configured container; limited logic |
Role-to-group mapping | Built in, rule-based | Not available out of the box; manual |
Hire-date timing | Times creation to the isolved hire date | Usually creates on next sync, not the start date |
Multi-company clients | Legal-company move stays one identity | Often reads a FEIN change as leaver plus duplicate joiner |
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 isolved 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 isolved structures. Legal company, department, job and work location 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.
Multi-company clients. One isolved client can hold several legal companies (FEINs), and employees move between them. Joinly applies rules to keep a single, stable AD object across the move, so a legal-company transfer swaps OU and groups rather than creating a duplicate account.
Payroll-driven dates and statuses. Hire and termination dates in isolved are pay-driven, and a Terminated status can reverse on a rehire or pay correction. Joinly reads the effective status and has the agent disable on the real termination date and reactivate cleanly on a rehire.
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 isolved 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 regional logistics SMB with around 900 employees across three depots, running isolved People Cloud but still living in an on-premise Active Directory for its warehouse and dispatch systems. Every new driver, picker or dispatch clerk starts as an isolved request that IT processes by hand in AD — creating the object, choosing the OU, building the login, adding groups. With seasonal contracts and frequent moves between depots and legal companies the queue never empties, and new joiners wait until day two or three for their account.
Connect isolved to Active Directory with Joinly and that work disappears. The Joinly AD Agent creates each user in the right OU on the hire date, builds a unique sAMAccountName, adds the correct security groups, moves people on a depot or legal-company transfer and disables accounts on the termination date with a 30-day grace window — all driven by the HR change in isolved People Cloud.
“An account is simply ready in the right OU when the clerk walks in, a move between legal companies just relocates the object, and we can show the auditor exactly which isolved change created every bit of access.” — Head of IT, regional logistics SMB
The outcome this setup is designed for: onboarding drops from days to zero touch, duplicate accounts from legal-company moves 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 isolved 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 isolved 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 isolved integration in the Joinly marketplace
Open the Joinly marketplace and search for the isolved 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 isolved integration.
3. Follow the installation wizard
You may be redirected to integrations.joinly.app. Create an account there and enter your isolved connection details: the API base URL and the OAuth Client ID and secret from the API Application registered in your isolved tenant. All data is encrypted and stored securely.

Enter your isolved API base URL and OAuth Client ID and secret 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 legal company, department and work location, 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 isolved flows through the agent to AD. Add a threshold workflow that disables the account a set period after the termination 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 isolved 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 isolved structures like legal company, department and work location, 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 isolved 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.
