Closes#11923
# Which Problems Are Solved
Client-side gRPC errors (e.g. NotFound, InvalidArgument,
PermissionDenied) were being surfaced as HTTP 500 Internal Server
Errors, causing false SRE alerts and poor UI feedback.
# How the Problems Are Solved
- New transport interceptor (`error-classification.ts`): Automatically
enriches every ConnectError with httpStatus and isUserError metadata via
a `ClassifiedConnectError` wrapper
- Route handler protection (`route.ts`, `flow-initiation.ts`): Catches
classified errors from `getAuthRequest` / `getSAMLRequest` and returns
correct HTTP status codes instead of 500
- Type safety: Replaced all magic number error.code === 9 checks with
typed Code.FailedPrecondition + instanceof ConnectError across
`oidc.ts`, `saml.ts`, `password.ts`, `zitadel.ts`
- Classification-aware logging (`session.ts`): Client/user errors log at
warn level, server errors at error level
- Observability (`otel.ts`): Spans now include error.is_user_error and
http.status_code attributes for alert filtering
# Additional Changes
Gitignore `next-env.d.ts`: This file is auto-generated by Next.js on
every next dev and next build invocation. The two modes write slightly
different import paths (.next/dev/types/ vs .next/types/), which causes
git diff --exit-code to fail in CI whenever a developer runs next dev
locally before committing. Since Next.js regenerates it automatically,
there's no need to track it

# Which Problems Are Solved
Invalid formatting in the login codebase due to invalid prettier
configuration
# How the Problems Are Solved
Fxed .prettierignore wildcards for login source files
# Additional Changes
Removed .prettierrc file because there is already a prettier.config.mjs
file
# Additional Context

# Which Problems Are Solved
This PR refactors the SAML Post binding flow to address issues with
payloads exceeding browser cookie size limits (typically ~4KB).
Previously, the SAML form data was serialized into a cookie, and the
user was redirected to an intermediate /saml-post page to render the
form. This approach failed for large SAML assertions.
# How the Problems Are Solved
The new implementation bypasses cookies entirely for the payload
transfer. Server actions now return the form data directly to the
client, which immediately renders and submits the form.
- Direct Data Transfer: Updated `startIdentityProviderFlow` to return an
object { url, fields } instead of a redirect URL when the next step is
formData.
- Server Actions: Updated redirectToIdp, sendLoginname, and
completeAuthFlow to propagate this samlData object to the client.
- Client-Side Auto-Submission: Added a new AutoSubmitForm component that
renders a hidden form with the provided fields and automatically submits
it to the IdP on mount.

Closes#11184
# Which Problems Are Solved
- loginName: This information is already retrievable from the URL
parameters during the authentication flow, so logging it presented no
additional exposure.
- idpIntent: This was being logged to the server console (server-side
logs), so it was never exposed to the client/browser.
These changes simply clean up the server logs to prevent unnecessary
data noise.
# How the Problems Are Solved
- Removed idpIntent logging from
`apps/login/src/lib/server/idp-intent.ts`
- Removed loginName logging from
`apps/login/src/lib/server/password.ts`

Closes#11191
# Which Problems Are Solved
This PR fixes the IDP linking for accounts with no authentication
method.
We strictly validate session ownership and generate a hash of the
sessionId + the user's fingerprintId cookie. This hash is passed to the
IDP as linkFingerprint.
This PR addtionally addresses TypeScript errors regarding unknown types
in catch blocks within the IDP intent processing logic. It ensures that
errors occurring during IDP linking are safely handled, and that
meaningful error messages are propagated to the client-side redirect
URLs.
# How the Problems Are Solved
- Safely handle unknown errors: Updated catch blocks in
`processIDPCallback` to check if the caught object is an instance of
Error before accessing error.message.
- Fix "IDP Taken" check: Implemented a safe check for the gRPC error
code 6 (Already Exists) by casting the error, resolving the Property
'code' does not exist on type 'unknown' build error.
- Error Propagation: The specific error message is now passed to the
linking-failed page params, allowing for better user feedback instead of
generic errors.

# Which Problems Are Solved
User profile updates were not propagated when using External OIDC IDP +
Login V2
# How the Problems Are Solved
* `UpdateHumanUserRequest` is added to
`RetrieveIdentityProviderIntentResponse`
* `UpdateHumanUserRequest` is returned in the
`RetrieveIdentityProviderIntentResponse` when the user already exists
during external IDP auth, which is then used in the frontend to update
the user info
# Additional Changes
* Moved integration tests related to user intent to a separate test file
* Fix redirection after external IDP user registration

# Which Problems Are Solved
When users authenticate via IDP (Identity Provider) without explicit
organization context, the flow could fail or create users without proper
organization assignment. This occurred when:
- No organization parameter was provided in the IDP callback
- Domain discovery didn't find a matching organization
- OIDC requests didn't include organization scopes
# How the Problems Are Solved
Implemented a fallback mechanism that ensures organization context is
always available:
- Centralized organization resolution in `resolveOrganizationForUser()`
- First: Use explicitly provided organization
- Second: Attempt domain discovery from username
- Third: Fallback to default organization (NEW)
- Explicit error handling: Users are never created without organization
context. If no organization can be determined (including no default
org), the flow fails gracefully with a clear error message.
- Applied to both creation flows:
- CASE 4: Auto-creation of users
- CASE 5: Manual user registration

Closes#10828
# Which Problems Are Solved
The IDP callback flow was calling retrieveIDPIntent() twice, causing
single-use token failures with error: "Intent Token is invalid". This
occurred due to Next.js 15's dynamicIO feature triggering double renders
# How the Problems Are Solved
Completely refactored the IDP callback architecture to ensure single-use
tokens are consumed exactly once:
- Centralized Business Logic: Moved all IDP callback logic into a single
server action (processIDPCallback) that:
- Consumes the token once
- Handles all 6 business scenarios (login, linking, auto-linking,
auto-creation, manual registration, account not found)
- Integrates session creation in the same action
- Returns `{ redirect?: string; error?: string }` for client-side
navigation
- Client Component Invocation: Created `IdpProcessHandler` client
component that:
- Calls the server action from browser context (enables cookie
modification)
- Prevents double execution with useRef
- Handles loading states and error display
- Clean Architecture:
- Removed 403-line success page with complex logic
- Removed component files from `/components/idps/pages/` folder
- Moved all UI directly into server pages
- Created dedicated result pages with minimal params
# Additional Changes
- Added translations to all 8 supported languages
