Aug 1, 2025August 2025: Focused bug fix in LDAP group management for opf/openproject by implementing alphabetical sorting for the LDAP group selection dropdown. This change makes the dropdown deterministic by ordering groups by lastname ascending and plucking the relevant fields, addressing the issue of unpredictable group listings and reducing admin selection errors. Implemented in commit bba86ec4e6286dc7e241b78310288e075c2dabba, linked to OpenProject issue #66582. This improves admin efficiency and data accuracy with minimal risk to existing workflows.
