feat(core, react): add copyable sp issuer urn field to saml sso setup

[chakrihacker]

Summary

Adds a read-only, copyable SP Issuer URN (Service Provider Entity ID) field to the SAML
connection create and edit views, completing the set of copyable SP fields alongside
Callback URL, ACS URL, and SP Metadata URL.

Why

The SAML connection setup exposed Callback, ACS, and SP Metadata URLs but not the SP
Issuer URN (Entity ID), which admins need to configure the Service Provider identity in
their SAML IdP. Unlike the other three fields, the URN requires the tenant name — which
UI Components cannot derive on its own — so the host must be able to supply it.

What

• New read-only, copyable SP Issuer URN field in the SAML create and edit views,
  rendered as urn:auth0:{tenantName}:{connectionName}.
• New optional resolveSamlMetadata?: ({ connectionName }) => { entityId } prop on
  SsoProviderCreate, SsoProviderDetails, and the provider-configure props, letting the
  host supply the tenant name and full connection-name prefix.
• Fallback when the prop is absent: urn:auth0:{domain-derived-tenant}:{connectionName},
  derived from the core client domain.
• The URN is display-only — excluded from the submitted form payload
  (formRef.getData()).
• Added sp_issuer_urn label and helper text to en-US, fr, and ja translations.

Testing

How can this be verified? Note anything intentionally not covered by tests and why.

1. Start an example app and open the My Organization → SSO provider create flow.
2. Select the SAML strategy and enter a connection name.
3. Confirm the SP Issuer URN field renders read-only and copyable, showing
   urn:auth0:{tenant}:{connectionName}.
4. Pass a resolveSamlMetadata prop and confirm the field uses the returned entityId.
5. Omit the prop and confirm the domain-derived fallback value renders.
6. Open the edit view for an existing SAML connection and confirm the field appears there too.

• This change adds unit test coverage
• Tested for both SPA and RWA flows, all example apps working
• All existing and new tests complete without errors

Checklist

• Breaking change
• Requires docs update
• Backward compatible

Summary by CodeRabbit

• New Features
  • SAML provider configuration now displays the SP issuer URN in a read-only, copyable field with localized guidance.
  • The issuer value can come from resolved SAML metadata or be generated from the tenant domain and connection name. If no connection name is provided, the field remains empty.

📝 Walkthrough

Walkthrough

The SAML provider configuration now displays a read-only, copyable SP issuer URN. The form uses an optional metadata resolver when provided, or builds a URN from the tenant and connection name. English, French, and Japanese translations and form tests are updated.

Merge Risk: 🟡 Moderate · up to e943b

The new SP Issuer URN field is meant to be copied into an identity provider. When the host app does not supply a resolver, the displayed value is guessed from the domain and can differ from the real entity ID, for example on custom domains. An administrator who copies the wrong value could end up with a SAML integration that fails at login. Make the fallback accurate, or require an authoritative value, before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to e943b

The new copyable issuer could help administrators configure SAML, but the default value is derived from a domain rather than confirmed against the service provider’s actual identity. A mismatch could lead to an incorrect identity being configured at an IdP.

Retained concerns

• Medium · security · inferred: When no resolver is supplied, the copyable issuer is inferred from the domain’s first segment. For a domain whose first segment is not the tenant name, that value may differ from the service provider’s actual entity ID and be copied into an IdP configuration. Runtime equivalence has not been established.

Security review details

Security Blast Radius

• inferred — The direct new exposure is the issuer presented in SAML create and edit views and potentially copied into an IdP. The evidence does not establish a new network entrypoint or a change to submitted provider data.

Security Findings and Attack Paths

• inferred — A domain-derived value that differs from the actual SP entity ID could misconfigure an IdP and disrupt SAML sign-in. The available evidence does not establish an authentication bypass, cross-tenant access, or an actual mismatched deployment.

Trust Boundaries and Controls

• observed — The embedding host may supply the displayed identity through the resolver. Without it, the UI constructs an identity from the core-client domain; the displayed value is not part of the form data returned for saving.

Hardening Proposals

• proposed — Source the copyable issuer from authoritative SP metadata, or establish and verify the domain-to-tenant rule before relying on the fallback, particularly for custom domains.

- Around line 130-132: Update the fallback that builds the SAML issuer from
`domain` and `connectionName` to use an authoritative tenant identifier or the
configured `connection.options.entityId`, rather than inferring the tenant from
the domain’s first segment.
