* Make authentication mode and credentials configurable via CLIThomas Vanbesien3 days3-43/+197
| | | | | | | | | | | | | Replace hardcoded user/password credentials with a new <auth-mode> parameter that accepts "anonymous" or "user". When "user" is chosen, two additional <username> <password> arguments are required. ServerRegister accepts two independent auth modes: one for its own server-side access control and one for authenticating to the LDS when registering. ClientFindServers passes credentials to readServerTime, which selects UA_Client_connectUsername or UA_Client_connect accordingly. Update CLAUDE.md running examples and add an auth modes table.
* Add username/password authentication to servers and clientThomas Vanbesien3 days3-1/+36
| | | | | | | | | Disallow anonymous sessions on both the LDS and registering server by configuring UA_AccessControl_default with a hardcoded user/password credential pair. Set UA_ClientConfig_setAuthenticationUsername on the client configs used for register, re-register, and deregister calls. Use UA_Client_connectUsername in the FindServers client when reading server time.
