okta provisioning failed ad agent connector down

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

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

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

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

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

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

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.
