SUMMARY
Dolphin is unable to create new folders/download-files-to/delete files off a Synology NFS mounted folder, despite the same user being able to, in the console.

STEPS TO REPRODUCE
1. NFS Mount Options in /etc/fstab are:
XXX.XXX.X.XXX:/volume1/XXXXX /XXXX/XXX nfs rsize=8192,wsize=8192,timeo=14,intr
2. Go to folder and try to create new folder, option is grayed out.
3. Try to create a folder in console, it works. But trying to delete it shows the prompt that the folder is "write-protected".
