Suggested reviewers: Merge Risk: 🟡 Moderate · up to Concurrent administrator removals could leave an organization without an active administrator. Serialize those changes before merging. Security Architecture ReviewSecurity architecture risk: 🟠 High · up to Provisioning and sign-in now share responsibility for account state. A concurrent sign-in reconciliation can lose a successful deactivation, and concurrent administrator removals can bypass the recovery safeguard. Organization-scoped authorization limits exposure, but these races affect offboarding and administrative recovery guarantees. Retained concerns

_user_name validates that the value is non-empty after .strip() but then returns value.lower() — the original, unstripped string. A userName with leading/trailing whitespace (e.g. " grace@example.org") passes validation and is stored verbatim (just lowercased), which can create confusing look-alike duplicates against the trimmed form. Compare with _group_changes's displayName handling a few lines below, which does strip (value.strip()[:100]) — this looks like an inconsistency/oversight rather than intentional.

Confidence: medium — this is a real edge case, though real-world IdPs (Entra/Okta) are unlikely to send padded usernames in practice.

_deactivate (line 368-374) already calls _remove_memberships for the non-managed branch, so this explicit call on line 987 re-runs the same DELETE statements (and demote_disallowed_public_projects) a second time for non-managed accounts. It's needed for the managed branch (since deactivate_account doesn't touch membership), but for non-managed accounts it's redundant work within the same request. Not incorrect, just a minor inefficiency — worth a comment or restructuring _deactivate to optionally always remove memberships, if that's easy to do cleanly.
Confidence: low — purely a quality/performance nit, no functional bug.

Summary
Part 3 of 3 for institutional sign-in in the reference projects/identity API (
backend/geolibre_server_api). It adds SCIM 2.0 provisioning per organization for IdPs such as Entra ID and Okta. Builds on the security policy (#2788) and OIDC federation (#2796).POST/GET/DELETE /api/organizations/{id}/scim-tokens. The raw token is shown once; only its digest is stored. Base URL is/scim/v2/{organizationId}.ServiceProviderConfig,ResourceTypes,Schemas),UsersandGroupsCRUD, paging, supported equality filters, PATCH operations including Entra ID's capitalization/string-boolean variants. SCIM errors and responses use the SCIM media type and error schema.docs/server-api.mddescribes token management, supported SCIM behavior, adoption/reconciliation, deactivation, and the admin protections.Testing
