TL;DR

Align the GitHub SCIM and SAML identities: the SCIM userName and the SAML nameID must refer to the same value (usually the same email or username), so correct whichever side drifted and reprovision, because GitHub refuses to merge a SCIM identity with a mismatched SAML identity. Prove it on one failing hire before rolling it to the rest of hires in the same sync or flow, because this fault repeats identically wherever the same condition holds and a fleet-wide or batch-wide first attempt multiplies the damage when the diagnosis is wrong.

GitHub SCIM provisioning failed "SCIM identity conflict, the SCIM identity and the SAML identity do not match"

Use this when

• You see this exact error or symptom: GitHub SCIM provisioning failed "SCIM identity conflict, the SCIM identity and the SAML identity do not match".
• The failure is in the provisioning path named in the title (HR source, identity provider, and target app), and it repeats on the same action rather than happening once and clearing.
• Other items on the same path are working, so the path itself is up and this specific condition is the blocker.

Not for this skill when

• A different error code, message, or tool is involved. Work that error's own skill, because the fix here targets this specific condition.
• The whole service or platform is down. Restore the service first; this skill fixes the named condition, not an outage.
• You cannot identify one affected item to test on. Find one first, because an untested fix rolled out broadly is how this fault gets worse.

Steps

1. Confirm the fault on one failing hire first and capture the evidence before changing anything: check the provisioning log entry for the one failing user in the identity provider (Okta system log, Entra provisioning logs, or the target app's SCIM log), and record the exact error text, the record or host involved, and the time it happened. Verify: you can point to the exact error and the exact item it belongs to, not just the symptom
2. Align the GitHub SCIM and SAML identities: the SCIM userName and the SAML nameID must refer to the same value (usually the same email or username), so correct whichever side drifted and reprovision, because GitHub refuses to merge a SCIM identity with a mismatched SAML identity. Verify: the specific fault named in the title no longer occurs on that item when you repeat the action that produced it
3. Make the operation idempotent: look the record up by its stable key before creating, adopt or update the existing record when it is the same entity, and log which path was taken. Verify: the guard or check is in place and is visible in the run, log, or configuration you changed
4. Retest end to end: rerun provisioning for that single user (on-demand provisioning or a sync cycle) and confirm the target account exists with the right attributes and status. Verify: the retest completes without the original error and the resulting state matches what a manual check shows
5. Roll the fix out to the rest of hires in the same sync or flow in the same way, watching the first few for the same error, and note the root cause and the change in the run or incident record. Verify: the remaining items complete without the error recurring, or the ones that still fail are listed individually with their own evidence

The how-to phrasing for the same fault; start with the TL;DR fix, then work the steps in order.

Compatibility: Okta, Microsoft Entra ID, Google Workspace, AWS IAM Identity Center, SCIM 2.0 targets and Terraform providers as named in the title.

Why it happens

This fault happens because create-style operations are not idempotent in most of these systems, so a retry or a pre-existing record surfaces as a hard conflict instead of a no-op. In this case the condition is the one named in the title, in the provisioning path named in the title (HR source, identity provider, and target app): the receiving or acting side reports the failure faithfully, but the underlying state (a record, a setting, a credential, a file, or a mapping) does not match what that action assumes. Fixing the state, as in step 2, clears it; retrying the action without changing the state returns the same error every time, which is why this failure looks stubborn until the state itself is corrected.

TL;DR

The app already has a user with the same identifying attribute, so SCIM create fails with 409. Match on the right attribute, import the existing user into Okta management, or merge the duplicates, then retry provisioning.

The query

scim 409 conflict "user already exists" during okta provisioning

Use this when

• Okta provisioning fails with 409 user already exists
• the user was created manually in the app before SCIM
• provisioning worked for others but fails for one user

Not for

• SCIM endpoint authentication failures
• schema or attribute mapping errors
• deprovisioning failures

Steps

1. Identify the matching attribute Okta uses, usually userName or email, and find the duplicate in the app. Expected output: the existing app-side user is located.
2. Check whether the existing account is the same person or a true collision. Expected output: identity confirmed as same person or different person.
3. If same person, use Okta import to bring the app user under management and link it. Expected output: the accounts are linked with no duplicate.
4. If different people, fix the colliding attribute (often a reused email) before retrying. Expected output: the collision is resolved.
5. Retry provisioning. Expected output: the create or update succeeds without 409.

Applies to

Okta Lifecycle Management SCIM provisioning, SCIM 2.0 apps, current Okta versions.

Variant phrasings

409 for every user in a new integration

The matching attribute is wrong globally; switch userName to email or the app ID.

409 after a rehire

The old app account was never deprovisioned; link or remove it first.

Why it happens

SCIM create is not idempotent against pre-existing accounts. Manual app-side creation before the integration, or a wrong match attribute, guarantees collisions.

Edge cases

• Some apps match case-sensitively; differing letter case in an email-style login name can still collide.
• Import first, then enable provisioning, on every new SCIM integration.
• Keep a list of manually created accounts to import during rollout.

TL;DR

Resolve the taken login outside the identity provider: the GitHub login already exists and is not managed by the IdP, so the account must be converted to enterprise managed membership or the new hire given a different login, because SCIM cannot claim an unmanaged existing account. Prove it on one failing hire before rolling it to the rest of hires in the same sync or flow, because this fault repeats identically wherever the same condition holds and a fleet-wide or batch-wide first attempt multiplies the damage when the diagnosis is wrong.
