Parent issue: https://github.com/sequentech/meta/issues/13842

Realm imports clear user credentials while retaining user metadata and service-account configuration. New tenant provisioning retains client-backed service accounts and an admin requiring password setup, and the shipped template carries no user credentials. Operator guidance covers initial admin setup and existing-account remediation.

Remote configuration strips imported user credentials, requires admin password setup, and aborts on invalid realm JSON. Its two isolated script regressions pass.

Validation: six focused Rust tests, strict Clippy for the actual policy modules, REUSE, formatting, and applicable shell checks pass. The owning Windmill crate compiles and passes both focused filters (six tests total).

Existing deployed accounts and sessions require the documented operator remediation. No deployment or account changes are performed by this PR.

Summary by CodeRabbit

  • New Features
    • New tenant setups include an admin account without a preset password; an initial password update is required. Configured service accounts and client settings are preserved, while other seeded human accounts are not included.
    • Tenant realm imports no longer retain stored user passwords. The template api-user account is disabled.
  • Documentation
    • Updated setup guidance explains how to set the tenant admin’s initial password and sign in to the Admin Portal.

📝 Walkthrough

Tenant realm preparation removes stored user credentials. Tenant creation retains client-backed service accounts, configures a passwordless admin account to update its password, and removes other seed users. Devcontainer setup assigns passwords to eligible local accounts. Documentation and tests cover these changes.

Changes: Tenant realm bootstrap

Layer / File(s) Summary
Realm credential cleanup
.devcontainer/keycloak/import/*, .devcontainer/remote-deployment/configure-environment.sh, packages/windmill/src/services/import/*, scripts/test_tenant_bootstrap_configuration.py
The realm template no longer contains stored user credentials, and api-user is disabled. Deployment preparation and realm import remove user credentials. Tests check credential removal, preservation of realm metadata and client settings, and failure on malformed realm JSON.
Tenant bootstrap admin policy
packages/windmill/src/tasks/*, docs/docusaurus/docs/07-developers/06-keycloak/developers_keycloak.md, docs/docusaurus/docs/10-try_it_out/01-full-standalone-deployment/README.md
Tenant creation retains client-backed service accounts, removes credentials from the admin, adds UPDATE_PASSWORD, and removes other seed users. Tests cover filtering and preservation. The documentation describes admin initialization, service-account handling, and migration steps.
Local development password setup
.devcontainer/scripts/init-cli.sh, .devcontainer/scripts/set-dev-passwords.sh
The devcontainer runs a password setup script after building the CLI. The script sets passwords for the tenant admin and trustees only when the users exist and have no password.

A transient lookup failure can replace an existing local account password, while a partial setup can leave an account unable to complete the intended login flow. Fix the script’s failure handling before merging.

What changed in this PR

This PR hardens Keycloak realm provisioning by ensuring shipped/imported realms never carry user credentials while preserving service-account configuration and enforcing initial admin password setup.

Changes:

  • Strip imported user credentials during realm secret removal and add Rust policy to keep only service accounts + a passwordless admin requiring UPDATE_PASSWORD for new tenants.
  • Update the remote deployment configuration script to remove user credentials from the realm JSON and fail fast on invalid realm JSON.
  • Add focused regression coverage (Rust unit tests + isolated Python script) and document operator steps for admin initialization/remediation.
File Description
scripts/​test_tenant_bootstrap_configuration.py Adds an isolated regression script to validate remote configuration behavior against synthetic realm inputs.
packages/​windmill/​src/​tasks/​tenant_bootstrap_admin.rs Introduces a tenant bootstrap policy to keep service accounts + passwordless admin, dropping human seed users.
packages/​windmill/​src/​tasks/​mod.rs Registers the new tenant bootstrap policy module.
packages/​windmill/​src/​tasks/​insert_tenant.rs Applies the new bootstrap policy when creating/upserting tenant realms.
packages/​windmill/​src/​services/​import/​realm_user_credentials.rs Adds shared logic + tests to strip user credentials from imported realms without losing metadata.
packages/​windmill/​src/​services/​import/​mod.rs Registers the new realm credential-stripping helper module.
packages/​windmill/​src/​services/​import/​import_election_event.rs Invokes user-credential stripping as part of realm secret removal.
docs/​docusaurus/​docs/​07-developers/​06-keycloak/​developers_keycloak.md Documents tenant realm bootstrap behavior and operator remediation steps.
.devcontainer/​remote-deployment/​configure-environment.sh Removes credentials from deployment realm JSON and enforces admin password update via required action.
.devcontainer/​keycloak/​import/​tenant-90505c8a-23a9-4cdf-a26b-4e19f6a097d5.json Removes embedded credential blobs from the shipped realm template and adds UPDATE_PASSWORD for admin.

Keep the template's accented text as written, name the realm template and
show jq's error when credential removal fails, skip the script test without
jq, and state the service-account contract in its test.

The realm template no longer carries the admin password, so the guide now
tells the operator to set it in the Keycloak console.

✅ Action performed

Review finished.

Note: CodeRabbit is an incremental review system and does not re-review already reviewed commits. This command is applicable only when automatic reviews are paused.

The template's `api-user` stayed enabled in the admin group with no
credentials, so a password set on it later would give a working
administrator account. Nothing signs in with it; it is now disabled,
with a regression test next to the template's no-credentials test.

Without template passwords, a fresh devcontainer's `config-cli.sh` could
not sign step-cli in as the tenant `admin`, and the dev tooling's
`TRUSTEE1_PASSWORD`/`TRUSTEE2_PASSWORD` no longer matched any account.
`init-cli.sh` now sources `set-dev-passwords.sh`, which gives the local
`admin`, `trustee1` and `trustee2` those development passwords through
the Keycloak admin API, only when they have none, and clears the admin's
`UPDATE_PASSWORD` action. Deployments are unaffected.

Validation: the focused Windmill `realm_user_credentials` and
`tenant_bootstrap_admin` tests pass (7). `set-dev-passwords.sh` was run
twice against Keycloak 26.0 with a synthetic realm: it set the missing
passwords, kept an existing one, changed nothing on the second run, and
the admin's password grant then succeeded.

- Around line 32-35: Update the existing-password branch in the password setup
flow to check and remove the blocking UPDATE_PASSWORD required action before
returning. This lets reruns complete accounts where password reset succeeded but
the user update failed; preserve the existing return behavior once the action is
reconciled.
- Around line 32-36: Update the credentials lookup before `reset-password` to
distinguish request failure from a successful response with no password
credential. Return without resetting the password when `curl` fails; continue to
`reset-password` only when the request succeeds and `jq` confirms no password
credential exists.
- Line 18: Update the curl requests that use KEYCLOAK_ADMIN_PASSWORD and bearer
tokens so secret values are not exposed in process arguments; pass the
URL-encoded password through stdin and provide sensitive headers through a
mechanism that keeps their values out of the argument list.

🔒 Security & Privacy | 🟡 Minor | ⚡ Quick win

Keep Keycloak credentials out of curl arguments.

--data-urlencode "password=$KEYCLOAK_ADMIN_PASSWORD" puts the bootstrap password in the curl process arguments. The bearer-token headers on Lines 25, 32, 38, 43, and 53 expose tokens in the same way. Pass the password through stdin and supply sensitive headers without placing their values in arguments. curl supports reading URL-encoded data from stdin. (curl.se)

Based on learnings: Shell secrets should be supplied through secure files or stdin rather than exposed through variables and command-line arguments.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Complete a partially finished password setup on the next run.

If reset-password succeeds but the user update on Line 43 fails, the account has a password and retains UPDATE_PASSWORD. The next run exits here, so it never removes the action that blocks the CLI password grant. Check and reconcile the required action for an account with a password before treating it as complete.

Stop when the credential lookup fails.

If the credentials request returns an error, the if condition is false. The script then resets the password even when the account already has one. Separate a successful response with no password from a failed request, and return before reset-password on failure. Keycloak documents this lookup as a separate API request that can return an error.
