+### Completed (2026-02-08) - OAuth2/OIDC for Grafana
+
+**OAuth2 client deployed for Grafana on monitoring02:**
+- Client ID: `grafana`
+- Redirect URL: `https://grafana-test.home.2rjus.net/login/generic_oauth`
+- Scope maps: `openid`, `profile`, `email`, `groups` for `users` group
+- Role mapping: `admins` group → Grafana Admin, others → Viewer
+
+**Configuration locations:**
+- Kanidm OAuth2 client: `services/kanidm/default.nix`
+- Grafana OIDC config: `services/grafana/default.nix`
+- Vault secret: `services/grafana/oauth2-client-secret`
+
+**Key findings:**
+- PKCE is required by Kanidm - enable `use_pkce = true` in Grafana
+- Must set `email_attribute_path`, `login_attribute_path`, `name_attribute_path` to extract from userinfo
+- Users need: primary credential (password + TOTP for MFA), membership in `users` group, email address set
+- Unix password is separate from primary credential (web login requires primary credential)
+
 ### Next Steps
 
 1. Enable PAM/NSS on production hosts (after test tier validation)
 2. Configure TrueNAS LDAP client for NAS integration testing
-3. Add OAuth2 clients (Grafana first)
+3. Add OAuth2 clients for other services as needed

+## Current Progress
+
+### monitoring02 Host Created (2026-02-08)
+
+Host deployed at 10.69.13.24 (test tier) with:
+- 4 CPU cores, 8GB RAM, 60GB disk
+- Vault integration enabled
+- NATS-based remote deployment enabled
+
+### Grafana with Kanidm OIDC (2026-02-08)
+
+Grafana deployed on monitoring02 as a test instance (`grafana-test.home.2rjus.net`):
+- Kanidm OIDC authentication (PKCE enabled)
+- Role mapping: `admins` → Admin, others → Viewer
+- Declarative datasources pointing to monitoring01 (Prometheus, Loki)
+- Local Caddy for TLS termination via internal ACME CA
+
+This validates the Grafana + OIDC pattern before the full VictoriaMetrics migration. The existing
+`services/monitoring/grafana.nix` on monitoring01 can be replaced with the new `services/grafana/`
+module once monitoring02 becomes the primary monitoring host.
+
 ## Open Questions
 
-- [ ] What disk size for monitoring02? 100GB should allow 3+ months with VictoriaMetrics compression
+- [ ] What disk size for monitoring02? Current 60GB may need expansion for 3+ months with VictoriaMetrics
 - [ ] Which dashboards to recreate declaratively? (Review monitoring01 Grafana for current set)

+## OAuth2/OIDC Login (Web Services)
+
+For OAuth2/OIDC login to web services like Grafana, users need:
+
+1. **Primary credential** - Password set via `credential update` (separate from unix password)
+2. **MFA** - TOTP or passkey (Kanidm requires MFA for primary credentials)
+3. **Group membership** - Member of `users` group (for OAuth2 scope mapping)
+4. **Email address** - Set via `person update --mail`
+
+### Setting Up Primary Credential (Web Login)
+
+The primary credential is different from the unix/POSIX password:
+
+```bash
+# Interactive credential setup
+kanidm person credential update <username>
+
+# In the interactive prompt:
+# 1. Type 'password' to set a password
+# 2. Type 'totp' to add TOTP (scan QR with authenticator app)
+# 3. Type 'commit' to save
+```
+
+### Verifying OAuth2 Readiness
+
+```bash
+kanidm person get <username>
+```
+
+Check for:
+- `mail:` - Email address set
+- `memberof:` - Includes `users@home.2rjus.net`
+- Primary credential status (check via `credential update` → `status`)
