…pache#61673) This PR addresses several issues in the FE LDAP authentication path that could lead to login hangs, indefinite blocking, unstable search latency, and poor observability when the LDAP server is slow or unavailable. The main changes are: - Add configurable LDAP timeouts, `ldap_connect_timeout_ms` and `ldap_read_timeout_ms` (both default to 5000 ms), so LDAP bind and search operations do not block indefinitely. - Fix LDAP search connection management by removing the conflicting JNDI built-in pooling configuration and adding `ldap_search_use_pool` to support both pooled and non-pooled search mode. - Improve diagnosability by adding structured performance logs across the LDAP authentication chain, including password resolution, bind, user lookup, group lookup, cache hit/miss, and authentication result. Together, these changes improve FE LDAP authentication stability, make timeout behavior explicit and configurable, reduce the risk of login stalls, and provide better diagnostics for production issues.
