Inline comments:
In `@backend/.mockery.private.yml`:
- Around line 418-433: Remove the duplicate
github.com/thunder-id/thunderid/internal/scim mapping in the configuration,
keeping one complete config block with its existing settings and deleting the
second identical block.
In `@backend/internal/scim/config/config.go`:
- Around line 18-20: Update the PatchSupported constant to true so
ServiceProviderConfig accurately advertises the registered group PATCH endpoint
and preserves group membership-delta behavior; keep its documentation consistent
with the enabled capability.
Apply the same fix in `@api/scim.yaml` around lines 59 - 60.
In `@backend/internal/scim/core_attr_mapper.go`:
- Around line 351-359: Update mapToCoreAttrs so the kindMultiComplex address
handling merges the normalized formatted address into the existing
result["addresses"] entry rather than overwriting it when addrParts are also
present. Preserve both the formatted value from normalizeToMultiComplex and the
individual address-part fields, ensuring the final SCIM addresses response
contains all mapped data.
In `@backend/internal/scim/discovery_handler_test.go`:
- Line 19: Update the host value in testBaseURL to use the approved ThunderID
product name (or the file’s appropriate template placeholder) instead of the
bare “thunder” term, while preserving the URL’s role in the test.
In `@backend/internal/scim/groups_resource.go`:

resolveThunderExtensionURN, thunderPrefix, and thunderURNs; update the matching
test names in backend/internal/scim/groups_resource_test.go:14-18 and
backend/internal/scim/groups_service_test.go:530-539. Preserve structural
thunder+id identifiers and excluded import/package names.
- Around line 72-82: Update groupVersionState to build the ETag state from
canonical member identities rather than the raw group.Member values: exclude
Member.Display, sort the identities deterministically, and retain the group
display name in the state. Add the required sort support and ensure equivalent
membership sets produce the same state regardless of paging order or member
record renames.
In `@backend/internal/scim/groups_service.go`:
- Around line 75-96: Update ListGroups to replace the per-group
fetchAllGroupMembers calls with one group-service batch member lookup for all
returned group IDs, then associate each group’s members while building SCIM
resources and preserve existing error mapping and response behavior. Add the
batch lookup at the group service layer, reusing existing membership data access
and pagination semantics as needed.
- Around line 195-215: The membership replacement paths in ReplaceGroup
(backend/internal/scim/groups_service.go:195-215) and the scimPatchOpReplace
branch of applyMembersPatch (backend/internal/scim/groups_service.go:345-373)

departing members and adding only new members; introduce or reuse one shared
diff helper in both sites, preserving unchanged members and existing error
handling.

- Around line 80-84: Wrap r.Body with http.MaxBytesReader before each io.ReadAll
call in the SCIM handlers, including the paths around the referenced users
handler reads, using the appropriate request-size limit. Treat a max-bytes
overflow like other invalid bodies by returning ErrorInvalidRequestBody or the
established 413 SCIM error, while preserving existing empty-body handling.
Apply the same fix in `@backend/internal/scim/groups_handler.go` around lines 57 -
61: All three group-handler reads require the same request-size limit.
In `@backend/internal/scim/version.go`:
- Around line 28-53: Address the TOCTOU window around checkIfMatch by making the
user and group mutations atomic: preferably persist the resource version and use
conditional updates that require the expected version, or hold a row lock across
the version read and mutation in a transaction. Ensure concurrent PUT /Users,
PUT /Groups, and PATCH /Groups requests return 412 for stale ETags; if this
cannot be implemented here, create a tracking issue and document the limitation
for SCIM integrators.
In `@backend/internal/system/security/middleware.go`:
- Around line 36-48: Update the SCIM error branch around writeSCIMSecurityError
to set the same WWW-Authenticate challenge used by writeSecurityError whenever
statusCode is http.StatusUnauthorized, before writing the response body; leave
forbidden responses unchanged.
In `@tests/integration/scim/scim_filter_test.go`:
- Around line 79-84: Make the SCIM fixture attribute values unique across
parallel runs so global list/search TotalResults assertions remain exact. In
tests/integration/scim/scim_filter_test.go lines 79-84, prefix the given-name
and locality values and update the corresponding filter literals at lines 159,
171, and 179; in tests/integration/scim/search_test.go lines 69-72, prefix the
locality values and update the filter literals at lines 156 and 166. Keep the
createFilterFixtureUser fixtures and their filters consistent.
In `@tests/integration/scim/users_test.go`:
- Around line 263-277: Update the GET /Users test around scimRequest and
scimUserListResponse to fetch and aggregate every pagination page before
checking IDs, using the response’s pagination metadata and advancing the start
index until all resources are collected. Keep the existing orphan exclusion and
good-user inclusion assertions against the complete deployment-wide result, and
avoid assumptions about shared test data or page ordering.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win
PatchSupported = false contradicts the registered PATCH route.
backend/internal/scim/init.go lines 197-201 register PATCH /scim/v2/Groups/{id} and route it to gh.HandleGroupsPatchRequest. The PR description also lists group PATCH support. ServiceProviderConfig therefore advertises patch.supported=false while the server implements PATCH.
SCIM clients read ServiceProviderConfig to decide whether to send PATCH. With false, a compliant client uses PUT replace instead and loses membership-delta semantics on groups.
The doc comment also states the operation "is supported" while the value is false.
Set the constant to true, or state the intended scope in the comment if Users PATCH is deliberately excluded from the advertised capability.
Note that discovery_service_test.go asserts result.Patch.Supported == scimconfig.PatchSupported, so the test cannot detect a wrong constant value.

@ravindu439, understood. I will keep this finding open because patch.supported=false also advertises that Groups PATCH is unavailable.
If the intended contract is that clients must not use PATCH for any resource until Users PATCH exists, this behavior is consistent with that policy. However, SCIM clients will not discover the implemented Groups PATCH endpoint.

Track the non-atomic If-Match check before the SCIM API ships.
The documented TOCTOU window is a real lost-update path for PUT /Users/{id}, PUT /Groups/{id}, and PATCH /Groups/{id}. Two concurrent writers read the same version, both pass checkIfMatch, and the second write overwrites the first. Clients that use ETags expect 412 in that case, so the guarantee advertised by ServiceProviderConfig.etag.supported is weaker than the response headers imply.
Two options keep the current shape:
- Add a persisted version column and a conditional
UPDATE ... WHERE version = ?in the user and group stores. - Wrap the read and the mutation in one transaction with a row lock.
If neither lands in this PR, please open a tracking issue and note the limitation in the SCIM documentation so integrators do not rely on strict optimistic concurrency. I can draft the issue text.

Make the PATCH request atomic.
A successful earlier action remains committed when a later action fails. For example, applyDisplayNamePatch can update the group before a member operation returns an error at Line 263.
Apply all actions in one group-service transaction. Restore the original group when any action fails. Add a test with a successful display-name action followed by a failing member action.
RFC 7644 requires a PATCH request to be atomic and requires restoration of the original resource on an operation error. (rfc-editor.org)

@ravindu439, agreed. A correct fix needs an atomic operation at the group-service or persistence boundary. A local rollback in scimGroupsService.PatchGroup cannot reliably restore state if a later operation fails.
If this work is out of scope for this PR, please confirm that you want a follow-up GitHub issue. The issue can specify an atomic group update API and the SCIM PATCH rollback test.

Purpose
Adds SCIM 2.0 provisioning support to ThunderID, implementing RFC 7643 (Core Schema) and RFC 7644 (Protocol) so external identity providers and provisioning clients (Okta, Azure AD, Entra ID, etc.) can create, read, update, and delete Users and Groups against
/scim/v2using the standard SCIM wire format.Approach
New package:
backend/internal/scimStandalone SCIM layer sitting on top of the existing user, group, and entitype (user-type schema) services — it does not replace them, it translates between the SCIM wire protocol and ThunderID's native resource model.
Discovery endpoints (
discovery_handler.go,discovery_service.go,schema_builder.go)GET /ServiceProviderConfig— advertises supported capabilities (patch, bulk, filter, sort, pagination), public, no auth.GET /Schemas,GET /Schemas/{id}— returns the static coreUser/Groupschemas (RFC 7643 §4.1/§4.2) plus one dynamically generated extension schema per registered ThunderID user type, built from that type's attribute schema.GET /ResourceTypes,GET /ResourceTypes/{id}— advertisesUserandGroupresource types; theUsertype'sschemaExtensionsarray lists every registered user type's extension URN.Users (
users_handler.go,users_service.go,users_resource.go,users_model.go,scim_validator.go,core_attr_mapper.go)GET/POST /Users,GET/PUT/DELETE /Users/{id},POST /Users/.search,GET/PUT /Me.PATCH /Users/{id}returns501 Not Implementedper spec (not yet supported).urn:thunderid:params:scim:schemas:<userType>:2.0:User) identifying the target user type — unless the server has exactly one configured user type, in which case the extension URN may be omitted.core_attr_mapper.gobidirectionally maps SCIM core fields (userName,name.givenName/familyName,emails,phoneNumbers,addresses, etc.) to/from ThunderID attribute names (username,given_name,family_name,email, ...), so a SCIM client'suserNameand a ThunderID admin'susernameattribute stay in sync.eqcomparisons optionally joined byand(scim_filter.go);or,not, grouping, and any operator other thaneqreturn400 invalidFilter. Sorting (sortBy/sortOrder) is not implemented and returns400if requested.attributes/excludedAttributesquery params implement RFC 7644 §3.9 attribute projection on Users/Me; the two are mutually exclusive.Groups (
groups_handler.go,groups_service.go,groups_resource.go,groups_model.go)GET/POST /Groups,GET/PUT/PATCH/DELETE /Groups/{id}.PATCH(RFC 7644 §3.5.2) supports replacingdisplayName, adding/replacing/clearing the fullmemberslist, and removing a single member viamembers[value eq "{id}"].UserorGroup.Cross-cutting
response.go— singlemapSCIMErrortranslator from internaltidcommon.ServiceErrorcodes to SCIM HTTP status +scimType(RFC 7644 §3.12), so error-format decisions live in one place instead of being duplicated per handler. Internal ThunderID error codes are never sent to SCIM clients — only the standard{schemas, status, scimType, detail}shape.error_constants.go— oneSCIM-10xxinternal error per failure mode (missing schema URN, duplicate schemas, unknown user type, uniqueness conflict, mutability violation, invalid filter syntax, etc.), each carrying an i18n key + default message.Content-Type: application/scim+jsonis enforced on all write requests; wrong/missing Content-Type returns400 invalidSyntax./Bulkand root/.searchreturn501 Not Implementedrather than a generic 404, per spec.config/config.go— SCIM-specific server config (public URL for resourcelocationfields, whether GET responses include mapped core attributes).version.go— SCIM package version marker.Tests
