Stage 2b. LdapOpcUaUserAuthenticator was left registered nowhere by stage 2a; this removes it, its three test files, and the config surface that existed only to serve it. Deleted: LdapOpcUaUserAuthenticator, LdapOpcUaUserAuthenticatorTests, LdapAuthResilienceTests, LdapGlauthOutageLiveTests (19 tests). Also removed four Security:Ldap keys — AuthTimeoutMs, MaxConcurrentAuthentications, OutageFailureThreshold, OutageCooldownSeconds — plus their validator rules and binding/validator test coverage. Verified first that the ONLY consumers were the deleted class and the validator rules asserting them; none appear in any checked-in appsettings. Leaving them would have created exactly the dead-config surface #521/#524/#525 were filed to clear up. Worth stating why that resilience machinery does not need relocating rather than just deleting. It existed because the OPC UA SDK raises impersonation SYNCHRONOUSLY under a SessionManager-wide event lock, so a hung LDAP bind there serialized every session activation server-wide — Anonymous and X509 included. Key verification is one indexed lookup plus one HMAC with no network I/O, so the hazard the wall-clock bound, concurrency cap and outage circuit guarded against no longer exists on that path. LDAP now runs only on AdminUI login, an ordinary async request path where a slow directory affects the one request making it. ConnectionTimeoutMs is RETAINED: it is projected into the shared library and is not authenticator-specific. Docs corrected rather than left to rot: - CLAUDE.md's "LDAP Authentication" section described the deleted file as the data-plane authenticator. Rewritten, including a warning not to "restore" it on seeing the LDAP wiring that AdminUI legitimately still needs. - infra/README §5b (the GLAuth outage live gate) marked RETIRED with the reason, rather than silently dropped — the harness GLAuth is still used by OTOPCUA_HARNESS_USE_LDAP=1 and is unaffected. - docs/security.md's five-key resilience table cut to the one surviving key, and a new API-key identity section added. Historical archreview/ records are left as-is; they are dated accounts. Host.IntegrationTests 211 tests (was 230, i.e. exactly the 19 removed) with the same 3 pre-existing failures verified against clean master. Host 37, Security 89.

ZB.MOM.WW.OtOpcUa.Host.IntegrationTests
Two-node Akka cluster integration tests on top of TwoNodeClusterHarness.
Default mode (no infra required)
dotnet test tests/Server/ZB.MOM.WW.OtOpcUa.Host.IntegrationTests
Uses Microsoft.EntityFrameworkCore.InMemory for ConfigDb and a stub ILdapAuthService that
accepts any username when the password is valid-password. Each harness instance creates a
unique in-memory database scoped to its lifetime. This is the mode CI runs by default.
Real-infra mode (SQL Server + OpenLDAP)
When you need to exercise EF behaviors that diverge between providers (index uniqueness,
RowVersion concurrency, JSON columns, migration application) or a real LDAP bind, bring up
the bundled compose stack and set the env-var switches:
docker compose -f tests/Server/ZB.MOM.WW.OtOpcUa.Host.IntegrationTests/docker-compose.yml up -d
export OTOPCUA_HARNESS_USE_SQL=1
export OTOPCUA_HARNESS_USE_LDAP=1
dotnet test tests/Server/ZB.MOM.WW.OtOpcUa.Host.IntegrationTests
docker compose -f tests/Server/ZB.MOM.WW.OtOpcUa.Host.IntegrationTests/docker-compose.yml down -v
SQL Server mode (OTOPCUA_HARNESS_USE_SQL=1)
- Container:
mcr.microsoft.com/mssql/server:2022-latestonlocalhost:14331 - Each
TwoNodeClusterHarness.StartAsync()creates a unique databaseOtOpcUa_Harness_{guid}viaDatabase.EnsureCreatedAsync()and drops it onDisposeAsync()(best-effort). - Port
14331chosen to avoid colliding with thedocker-dev/fleet (which uses14330).
LDAP mode (OTOPCUA_HARNESS_USE_LDAP=1)
- Container:
bitnami/openldap:2.6onlocalhost:3894 - Users
alice/alice123andbob/bob123, all underou=FleetAdmin. - Port

Local-dev caveat
This dev VM (DESKTOP-6JL3KKO) does not run Docker locally. Real-infra mode runs on the
shared Linux Docker host (10.100.0.35) per docs/v2/dev-environment.md, or in CI on Linux.
