Cause

The default behavior of the ZFS Storage Appliance is to allow only root to change ownership of files. This is the POSIX compliant settings.

This setting does have practical uses, such as preventing users from avoiding quota limitations by changing the ownership of their files so that they no longer count against user quotas.

Solution

This setting can be changed at the share or project level. On the Share/General or Project/General tab, it is the last option in the Properties Section.

To change it at the share level, clear the "inherit from project" checkbox, then clear the "Restrict Ownership Change" checkbox.

Example of Share/General BUI screen:
