Java implementation of the knoe-auth identity backbone (Round 1):
authority/.../admin/ user admin REST endpoints (list, deactivate,
reset-totp, role management)
authority/.../enroll/ invite-OTP web enrollment flow — accepts invite
token, creates Kerberos principal via kadmin,
seeds TOTP secret, returns keytab
authority/.../provisioning/ contributor provisioning service — orchestrates
invite generation, principal lifecycle, role grants
authority/.../kerberos/
KadminClient.java typed wrapper around the kadmin(1) subprocess;
create/delete/get-keytab/change-password
GKE manifests:
deploy/gcp/gke/knoe-auth-deployment.yaml two-container Pod (knoe-auth HTTP
+ kdc sidecar) with keytab-bootstrap
initContainer
deploy/gcp/gke/knoe-kdc-configmap.yaml krb5.conf, kdc.conf, kadm5.acl and
entrypoint for the embedded KDC
deploy/gcp/gke/knoe-kdc-secrets.yaml placeholder template — real values
created by init_knoe_auth.sh via 1Password
See docs/plans/knoe-auth-round-1.md for full architectural narrative.
