This error appears when agents are set to synchronize posix or NTFS permissions and this cannot be fulfilled
How to resolve this error?
To fix, check the following:
1) When syncing NTFS permissions across Windows agents, check that agent runs (to sync permissions by DACL) as Local System or domain admin (to sync permission by owner group).
2) When syncing posix permissions, check that target agent shall have a user or group registered with same ID or name as source.
