docs(authbridge): fetch demo admin token from master realm (fixes null token)

[pdettori]

Problem

Following the AuthBridge demos (starting with weather-agent/demo-ui.md), the "Inside the pod, get credentials and send a request" step fails — ADMIN_TOKEN and the agent TOKEN both come back null.

The admin-token step does a password grant against the rossoctl realm with admin/admin:

ADMIN_TOKEN=$(curl -s .../realms/rossoctl/protocol/openid-connect/token \
  -d grant_type=password -d client_id=admin-cli -d username=admin -d password=admin | jq -r .access_token)

But admin/admin is the master realm credential. The rossoctl realm admin user has a randomly generated password (per show-services.sh). The grant returns 401 invalid_grant, jq yields the literal null, and everything downstream cascades to null.

Fix

Fetch the admin token from the master realm. admin/admin is stable and documented, and the master admin has cross-realm rights, so /admin/realms/rossoctl/clients still resolves. The client lookup and the agent client_credentials grant stay on the rossoctl realm.

Applied to all 9 admin-token password grants across 5 demo docs:

• weather-agent/demo-ui.md
• github-issue/demo-ui.md (×2)
• github-issue/demo-manual.md (×2)
• github-issue/demo-rbac.md (×2)
• github-issue/demo-aiac.md (×2, via REALM_NAME)

Misleading "from the rossoctl realm" comments updated to match.

Deliberately left unchanged: the WRONG_ISSUER_TOKEN master-realm negative test in demo-manual.md/demo-rbac.md, the client_credentials agent-token grants (correctly rossoctl), and /admin/realms/rossoctl/clients admin-API paths.

Verification

Ran the full sequence on a local Kind cluster with only the realm changed to master:

admin token len: 766
CLIENT_ID=spiffe://localtest.me/ns/team1/sa/weather-service  secret_len=32
agent token http=200  token_len=1262

Closes #797

Summary by CodeRabbit

• Documentation
  • Updated deployment and demo instructions to obtain administrator tokens from Keycloak’s master realm.
  • Clarified administrator credentials and noted that the application realm’s administrator password is randomly generated.
  • Corrected token-generation examples across GitHub issue, RBAC, UI, and weather-agent demos.

📝 Walkthrough

Walkthrough

The AuthBridge demo instructions now obtain Keycloak admin tokens from the master realm using admin/admin. Subsequent client and agent-token operations remain in the rossoctl realm where applicable.

Changes

AuthBridge demo token instructions

Layer / File(s)	Summary
Update admin-token instructions authbridge/demos/github-issue/demo-aiac.md, authbridge/demos/github-issue/demo-manual.md, authbridge/demos/github-issue/demo-rbac.md, authbridge/demos/github-issue/demo-ui.md, authbridge/demos/weather-agent/demo-ui.md	All affected admin-token examples now target Keycloak’s master realm. The guides document the admin/admin credentials where applicable. Subsequent realm-specific operations remain unchanged.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 3075f

The demos now request the admin token from the correct realm, but they still hardcode admin/admin, so environments using configured non-default credentials can fail before client lookup and authentication. Update the commands to use the configured credentials before merging.

Preserve the configurable Keycloak admin credential contract. The GitHub demo setup reads admin credentials from environment variables, but these commands hardcode admin/admin. Custom credentials therefore cause the master token request to return 401 and downstream client lookup to fail.

Correct, well-scoped fix for the null admin token. Verified live on a Kind cluster (kind-rossoctl): the old rossoctl-realm grant with admin/admin returns invalid_grant / Invalid user credentials (the null cascade you describe), while the new master-realm grant returns a token of length 766 — matching your own verification exactly. The master admin token also retains cross-realm rights: GET /admin/realms/rossoctl/clients → HTTP 200, so the downstream client lookup and agent client_credentials grant on the rossoctl realm still resolve.

Diff scope is exactly the 9 admin-token password grants; client lookups, agent client_credentials grants, and the WRONG_ISSUER master-realm negative test are correctly left untouched.

One non-blocking nit inline about comment parity in demo-aiac.md.

nit — the other four docs gained a clarifying comment (# Get a Keycloak admin token from the master realm (admin/admin; the rossoctl realm admin password is randomly generated)), but the two admin-token grants in this file (this line and ~631) switch to realms/master with no comment while REALM_NAME="rossoctl" still sits just above. For parity with the sibling docs — and to explain the master-vs-rossoctl split to a reader — consider adding the same one-line comment here. Not blocking.
