ClickHouse removes the use of subprocess execution for Kerberos initialization, replacing it with a more integrated approach and adding a new integration test to ensure stability.
Why it matters
This change improves the reliability and security of Kerberos authentication by eliminating the need to run external subprocesses for initializing Kerberos credentials, thereby simplifying the codebase and reducing potential issues related to subprocess management.How to use it
Users do not need to take any additional steps to enable this feature; the Kerberos initialization process is now integrated directly within ClickHouse, and the new integration test validates its functionality automatically.
