GitHub SCIM sync failed team membership mismatch

Not specified by the original author.

TL;DR

Reconcile the IdP groups with the GitHub teams: the sync fails where the two disagree about who belongs where. Fix the mapping, then re-sync.

Error

GitHub SCIM sync failed: team membership mismatch

Steps

1. Identify the mismatched teams from the SCIM provisioning logs. Expected: the affected teams known.
2. Compare the IdP group membership with the GitHub team membership for those teams. Expected: the discrepancies listed.
3. Fix the source of truth: update the IdP groups (preferred) or adjust the team mappings in the SCIM config. Expected: both sides agree.
4. Re-run the sync and verify team memberships match. Expected: sync succeeds.

When to use

• SCIM sync fails on team membership mismatches
• Teams were renamed on one side only
• Manual team edits fight the sync

When not to use

• The sync fails on authentication (a credential problem)
• Users are missing entirely (a provisioning problem)
• You do not use SCIM for teams (manage teams manually instead)

Tool compatibility

GitHub SCIM with Okta or Entra as the IdP.

Variant phrasings

mismatch after renaming a team

Renames break the mapping. Update the SCIM config to the new name.

manual GitHub team edits keep getting reverted

That is the sync working as designed. Make the change in the IdP group.

Why it happens

SCIM treats the IdP as the source of truth for team membership. Any out-of-band edit on the GitHub side creates a mismatch the next sync flags.

TL;DR

Remove the user from the organization first, then reclaim the seat. GitHub counts every org member as a seat, so membership must go before the license is freed.

Error

GitHub seat reclamation failed: user still in organization

Steps

1. Confirm the user is still an org member. Expected: membership confirmed.
2. Transfer any owned resources the offboarding requires (or document that none exist), then remove the user from the org. Expected: membership ended.
3. Verify the seat count dropped in org billing settings. Expected: the seat reclaimed.
4. If the user must keep access to some repos, convert them to an outside collaborator on those repos only. Expected: least-privilege access preserved.

When to use

• Seat reclamation fails because the user is still in the org
• Offboarded employees linger as members
• The error names org membership as the blocker

When not to use

• The user is already removed but the count is wrong (a billing sync delay)
• The issue is a SCIM team membership mismatch (a sync problem)
• The user should stay (then the seat is legitimately consumed)

Tool compatibility

GitHub organization administration and billing.

Variant phrasings

user removed but still billed

Billing can lag. Check again after the sync window before escalating.

reclamation via SCIM deprovision

SCIM deprovision removes the org membership; use it instead of manual removal.

Why it happens

GitHub's seat model is membership-based. Any removal flow that skips the org-removal step leaves the seat consumed.

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

how to fix GitHub SCIM provisioning failed "SCIM identity conflict

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.
