OSX can't copy files in finder when mapped uid-->sid

scottgelb — Thu, 05 Jun 2025 06:00:11 GMT

A customer noticed this issue with OSX finder and I am able to recreate in my VSIM. The issue occurs with cDOT 8.0, 8.1 and 8.2 in my testing.

When a volume has UNIX security style, OSX works to copy files for both command line (terminal) and Finder.

When a volume has an NTFS security style and there is an NFS export with a name-mapping UID to SID, OSX works to copy files from only command line. Finder fails to copy when mapping the uid to a sid. The odd behavior is that it works on terminal so we know the mapping is working.

Anyone seen this or know of any workarounds?

Workaround for the issue...Thank you to Justin Parisi for this...he figured this out. The fix is to change ntfs-unix-security-ops from fail to ignore in the export policy. Assuming the default policy at position 1... also make sure to go to advanced mode first

set adv

export-policy rule modify -policyname default -ruleindex 1 -ntfs-unix-security-ops ignore

set admin
