Marc Schier	296a904f34	Add full OPC UA Part 18 (Role management) support (#3778) ... * role management compliant with OPC UA Part 18 Server-side: - New IRoleManager / RoleManager with spec-correct status codes (Bad_AlreadyExists, Bad_NodeIdUnknown, Bad_RequestNotAllowed, Bad_NotFound) for every mutator per Part 18 4.2 / 4.4. - Pre-populate default identities for the three reserved well-known roles per Part 18 4.3 (Anonymous, AuthenticatedUser, TrustedApplication). - Reject mutations on reserved roles with Bad_RequestNotAllowed. - Validate IdentityMappingRuleType per Part 18 4.4.3 (empty criteria for Anonymous/AuthenticatedUser/TrustedApplication; upper-case hex for Thumbprint; Name=Value grammar for X509Subject). - Honour Part 18 4.4.2 default-field-as-wildcard EndpointType comparisons; tighten TrustedApplication/Application rules to require trusted certificate + signed channel. - Introduce CustomConfiguration flag per Part 18 4.4.1. - Add IRoleManager.RoleConfigurationChanged event raised after every successful mutation per Part 18 4.4.1. - Make RoleEntry an immutable snapshot. Address-space binding (typed proxies): - RoleStateBinding switched from stringly-typed OnCallMethod2 plumbing to the source-generated typed proxies (RoleSetState, RoleState, AddRoleMethodState, AddIdentityMethodState, ...). - DiagnosticsNodeManager.AddBehaviourToPredefinedNodeAsync upgrades passive BaseObjectState nodes of RoleSetType / RoleType to the typed RoleSetState / RoleState proxies at predefined-node load time. - New RoleAuthorizationGate.CheckAdmin centralizes SecurityAdmin role plus SignAndEncrypt enforcement per Part 18 4.2 / 4.4 / 5.2. - Bound writable ApplicationsExclude / EndpointsExclude / CustomConfiguration with the same auth gate. - Raise RoleMappingRuleChangedAuditEventType from every successful mutator (Part 18 4.5) via the existing AuditEvents helper. Client library: - New Opc.Ua.Client.Roles.RoleManagementClient + IRoleManagementClient + RoleInfo + SessionRoleExtensions.OpenRoleManagementClient. - Covers list / read / add / remove role, identity, application, endpoint operations plus Set*Exclude via Write Service. Tests: - New RoleManagerTests.cs - 37 NUnit tests for pre-populated roles, reserved-role immutability, spec-correct status codes, criteria validation, ResolveGrantedRoles, exclude semantics, CustomConfiguration, AddRole well-known NodeId reuse, and RoleConfigurationChanged event. Documentation: - Rewrite Docs/RoleBasedUserManagement.md as a Part 18 compliance reference (status-code matrix, client examples, known limitations). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Add Part 18 5 UserManagement implementation Server-side: - New IUserManagement interface (Opc.Ua.Server.UserManagement) modelling Part 18 5.2.1 surface: PasswordLength, PasswordOptions, PasswordRestrictions, SnapshotUsers, AddUser, ModifyUser, RemoveUser, ChangePassword, MustChangePassword, IsUserActive, UserDeactivated event. - Default UserManagement implementation wraps the existing IUserDatabase and stores per-user UserConfigurationMask + description in memory. Validates passwords against PasswordLength + character-class flags from PasswordOptions; honours Part 18 5.2 result codes (Bad_AlreadyExists, Bad_NotFound, Bad_OutOfRange, Bad_NotSupported, Bad_ConfigurationError, Bad_InvalidSelfReference, Bad_IdentityTokenInvalid). - ChangePassword clears the MustChangePassword bit on success. - New UserManagementBinding wires the typed source-generated proxies (UserManagementState, AddUserMethodState, ModifyUserMethodState, RemoveUserMethodState, ChangePasswordMethodState) - typed OnCallAsync delegates everywhere; admin gate via RoleAuthorizationGate.CheckAdmin; ChangePassword gated via RoleAuthorizationGate.CheckSelfUserName; closes active sessions for deactivated users via ISessionManager. - ConfigurationNodeManager.AddBehaviourToPredefinedNodeAsync upgrades the passive UserManagement object to the typed UserManagementState proxy at predefined-node load time; CreateServerConfiguration invokes UserManagementBinding.Bind when an IUserManagement was injected. - IServerInternal gains UserManagement getter + SetUserManagement injector. Tests: - New Tests/Opc.Ua.Server.Tests/UserManagementTests.cs - 18 NUnit tests covering AddUser happy path, duplicate / password-length / config-flag validation, RemoveUser non-existent / self-reference / NoDelete, ModifyUser self-disable / disable-other UserDeactivated event, ChangePassword happy path / same-as-old / wrong-old / MustChangePassword bit clearing / NoChangeByUser rejection, IsUserActive on disabled vs active users. Documentation: - Update Docs/RoleBasedUserManagement.md with a User Management section including the spec result-code matrix, example wiring code, and reduce known limitations - UserManagement is no longer a limitation.	2026-05-20 05:51:17 +02:00
