Adds IOpcUaUserAuthenticator seam in OpcUaServer.Security with a deny-all NullOpcUaUserAuthenticator default. OpcUaApplicationHost subscribes to SessionManager.ImpersonateUser after _application.Start so UserName tokens flow through the authenticator and either attach a UserIdentity to the session (Allow) or set IdentityValidationError = BadIdentityTokenRejected (Deny / authenticator exception). Anonymous + X509 tokens fall through to SDK defaults. LdapOpcUaUserAuthenticator (Host project) bridges to the same ILdapAuthService that AddOtOpcUaAuth uses for Admin cookies / JWT, so a single LDAP source-of-truth governs both Admin control plane and OPC UA data plane. Program.cs registers LdapOptions + LdapAuthService + IOpcUaUserAuthenticator on driver-role hosts; admin-only nodes are unchanged. OtOpcUaServerHostedService threads the resolved authenticator into OpcUaApplicationHost so the seam respects Host DI. 10 new tests: 6 in OpcUaServer.Tests cover the pure HandleImpersonation static method (success / denial / anonymous fallthrough / authenticator- throw / null-username / Null authenticator); 4 in Host.IntegrationTests cover the LdapOpcUaUserAuthenticator adapter (LDAP allow → Allow with roles, LDAP deny → Deny, exception → backend-error denial, display-name fallback). OpcUaServer suite is 40 / 40 green. Closes #104. Unblocks Task 60 (dual-endpoint + ServiceLevel tests) once #81 residual lands.
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

LDAP mode (OTOPCUA_HARNESS_USE_LDAP=1)
- Container:
bitnami/openldap:2.6onlocalhost:3894 - Users

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.
