ObjectStore Standard 2025.1 Release Notes

New Features

● Support for Kerberos authentication on Windows

On Windows, ObjectStore now supports Kerberos as an authentication option. Starting with this version, NTLM (option NT_REMOTE) is no longer supported, as Microsoft is gradually removing it from Windows. For further information, see "Managing ObjectStore" guide: Chapter 2, section “Authentication Required”; Chapter 3, sections “OS_AUTH” and “OS_SPN (Windows only)”; Chapter 4, section “osserver”; and Chapter 8, section “Use Active Directory for Authentication”.

● Windows Server 2025 is now supported

Resolved Issues

● [GHI-12460] Fixes “"Error writing to (...)" when using OS_DEBUG_NETWORK=1”

A fix was implemented to avoid race conditions that were responsible for causing log files to have "Error writing to (…)" in specific conditions when using the OS_DEBUG_NETWORK environment variable with value “1”.

● [GHI-12565] Documentation updates regarding security configurations

A new subsection “Configuring Process Permissions for Enhanced Security (Windows only)” was added to the section “Managing Processes” of the Managing ObjectStore documentation file. This new subsection provides further details on how the environment variable OS_SECURITY_DESC_SDDL can be used to define fine-grained permission policies on the ObjectStore services via Security Descriptor Definition Language (SDDL).

● [GHI-12262] Upgrade of libexpat library

Libexpat was upgraded to version 2.7.1.
