Joseph Doherty 0f2b2b8351 feat(glauth): merged shared dev GLAuth directory + compose + runbook (10.100.0.35)
Phase 0 of the shared-GLAuth standardization. config.toml = merged dc=zb,dc=local
directory (15 groups in partitioned 55xx/56xx/57xx families, 14 users incl.
multi-role spanning all groups, serviceaccount search account). compose runs one
glauth/glauth:latest on :3893. README is the deploy/verify runbook. Code-reviewed;
fixed scp -r idempotency in the deploy command (README + plan Task 4).

Shared dev GLAuth (dc=zb,dc=local)

One GLAuth directory that all three sister apps use for dev/test auth — OtOpcUa, MxAccessGateway, ScadaBridge. It runs as a single container on the shared Docker host 10.100.0.35:3893 (plaintext LDAP). This is the app-neutral source of truth; each app just points its …Ldap:Server at 10.100.0.35.

Scope: dev/test only. Production uses real corporate AD. See ../../docs/plans/2026-06-04-shared-glauth-standardization-design.md.

Directory layout

Group families are partitioned into non-overlapping gid ranges so the three apps coexist — each app maps only its own family and ignores the rest.

Family Used by Groups (gidnumber)
SCADA-* (55xx) ScadaBridge roles (DB-mapped) Admins 5501, Designers 5502, Deploy-All 5503, Deploy-SiteA 5504, Viewers 5505
OPC-perm (560x) OtOpcUa + MxGateway OPC-UA write model ReadOnly 5601, WriteOperate 5602, WriteTune 5603, WriteConfigure 5604, AlarmAck 5605
Gw* (561x) MxGateway dashboard (config-mapped) GwAdmin 5610, GwReader 5611
OtOpcUa-* (57xx) OtOpcUa AdminUI (DB-mapped) Admins 5701, Designers 5702, Viewers 5703

Users (all password password except serviceaccountserviceaccount123):

  • serviceaccount (cn=serviceaccount,dc=zb,dc=local) — the single bind account every app uses for search-then-bind. Has a search * capability.
  • multi-role — member of every group → all roles in all three apps (canonical cross-app login).
  • adminSCADA-Admins + GwAdmin + OtOpcUa-Admins → Administrator everywhere.
  • Per-role testers: designer / deployer / site-deployer (ScadaBridge); gwreader (MxGateway Viewer); otdesigner / otviewer (OtOpcUa); readonly / writeop / writetune / writeconfig / alarmack (OPC perms).

Deploy on 10.100.0.35

Access note: deploying needs working SSH/Docker access to 10.100.0.35. If your key is not authorized there, hand this folder to whoever administers the box and have them run the same docker compose up -d. The artifact is self-contained.

# From this repo root. Copy the FILES into the dest (not the dir) so a re-deploy
# doesn't nest them at ~/zb-glauth/glauth/ (scp -r of a dir into an existing dir).
ssh dohertj2@10.100.0.35 'mkdir -p ~/zb-glauth'
scp infra/glauth/config.toml infra/glauth/docker-compose.yml dohertj2@10.100.0.35:~/zb-glauth/
ssh dohertj2@10.100.0.35 'cd ~/zb-glauth && docker compose up -d --force-recreate && docker ps --filter name=zb-shared-glauth'

Verify

Bind as the service account and confirm multi-role spans all four families:

ldapsearch -x -H ldap://10.100.0.35:3893 \
  -D cn=serviceaccount,dc=zb,dc=local -w serviceaccount123 \
  -b dc=zb,dc=local "(cn=multi-role)" memberOf
# → result: 0 Success. memberOf comes back as group DNs (e.g. ou=SCADA-Admins,ou=groups,dc=zb,dc=local)
#   spanning all four families: SCADA-*, ReadOnly/Write*/AlarmAck, GwAdmin/GwReader, OtOpcUa-*.
#   (The shared ZB.MOM.WW.Auth.Ldap lib strips each to its bare RDN, e.g. "SCADA-Admins", at login.)

Confirm a user authenticates with password (a bad password returns result: 49; this user lacks the search capability, so a successful bind shows result: 50 Insufficient access on the search):

ldapsearch -x -H ldap://10.100.0.35:3893 \
  -D cn=multi-role,dc=zb,dc=local -w password \
  -b dc=zb,dc=local "(cn=multi-role)" cn

No ldapsearch locally? Run it from a throwaway container:

docker run --rm alpine:3.20 sh -c 'apk add -q openldap-clients >/dev/null 2>&1 && \
  ldapsearch -x -H ldap://10.100.0.35:3893 -D cn=serviceaccount,dc=zb,dc=local -w serviceaccount123 \
  -b dc=zb,dc=local "(cn=multi-role)" memberOf'

Editing the directory

GLAuth uses the config datastore (this config.toml, mounted read-only). To add/change a user or group, edit config.toml and recreate the container — a plain restart keeps the stale file (single-file Docker bind-mount inode trap):

docker compose up -d --force-recreate

Group gidnumbers and user uidnumbers must stay unique across the whole file; keep new groups inside the per-app range (55xx / 56xx / 57xx) so the families don't collide.
