# Fix Okta provisioning failures when the AD agent is down

## TL;DR
The Okta AD agent is the bridge between Okta cloud and on-prem Active Directory: every AD-sourced provisioning task flows through it. If its service stops, every one of those tasks fails. Get the agent service running again on the domain-joined host, confirm it checks in to Okta, then retry the failed tasks. This is infrastructure, not a mapping problem.

## The error
```text
Provisioning task failed: "Unable to communicate with the Active Directory agent."
Okta Admin / Directory / Directory Integrations / Active Directory / Agents: status Down or last check-in hours old
```

```

## Fix it

### Step 1: Check the agent service on the host

```bash
On the domain-joined Windows host, open Services and find the Okta AD Agent service. Note whether it is stopped, and start it if so.
```

Expected: the service shows Running. If it stops again immediately, go to step 2 before retrying in Okta.

### Step 2: Read the agent logs for the real reason

```bash
Open the agent log files in the install directory's logs folder and read the most recent errors around the time the service stopped.
```

Expected: a concrete reason - TLS, proxy, credential, or disk issue. Fix what the log names.

### Step 3: Verify the host can reach Okta and the service account is valid

```bash
Confirm outbound HTTPS from the host to the Okta tenant succeeds, the proxy settings (if any) are correct, and the AD service account password has not expired.
```

Expected: connectivity works and the service account authenticates. An expired service-account password is the usual culprit.

### Step 4: Confirm the agent checks in to Okta

```bash
In Okta Admin / Directory / Directory Integrations / Active Directory / Agents, verify the agent shows Active with a recent check-in timestamp.
```

Expected: green Active status. If it stays down, re-run the agent installer to re-register it rather than fighting the config.

### Step 5: Retry the failed provisioning tasks

```bash
Open the provisioning task queue, select the failed AD tasks, and retry them.
```

Expected: tasks complete successfully now that the agent is back.

## When this applies

- AD-sourced provisioning fails with agent communication errors
- The AD agent shows Down or a stale check-in in Okta
- All AD operations fail at once, not just one user

## When it doesn't

- Only some users fail (mapping or data issue)
- The agent is Active but tasks fail (look at the task error detail)
- Non-AD provisioning fails too (Okta-side or target-app issue)

## Compatibility

Okta Active Directory integration, Okta AD Agent on Windows Server. Same approach for the LDAP agent variant.

## Variant phrasings

### okta ad agent not checking in

Check-in failures are almost always network or credential: proxy, TLS, or the service account.

### okta active directory agent down provisioning failed

If the service will not stay running, the logs name the cause. Do not reinstall until you have read them.

## Why it happens

Okta cloud cannot reach on-prem AD directly, so all reads and writes go through the agent's outbound connection. When the agent service stops - crashed, patched, password expired, proxy changed - that connection dies and every AD operation fails with the same communication error. One broken bridge, not many broken users.

## Edge cases

- Agent auto-update can restart the service mid-day; schedule updates in maintenance windows
- Multiple agents: Okta fails over, but a half-dead agent can still accept and drop work; check each one
- Service-account password expiry locks the account after failed binds; use a managed non-expiring service account per policy

## If it still fails

- Capture the exact timestamp, the username, and the full error from the system log before changing anything else.
- Reproduce with a single test user so you are not debugging a crowd.
- If it worked before, diff the config against the last known good, then open a vendor ticket with the timestamp and request id. Never send secrets or private keys.

## Prevention

- Track credential and certificate expiry with alerts, not memory.
- Run a synthetic check per app daily so breakage pages you, not a user.
- Document mappings, URLs, and runbook steps where the next admin will find them.
