I'm in a similar situation - I've been following the instructions in the documentation, and with the info in this thread, I've been able to mount the volume for my external NTFS drive that is full of data.
Now, I'm attempting to set the permissions for a guest account, and they won't take. It takes forever if I choose the GUI option to set permissions recursively (I presume its due to the large file count). If I do it without that option checked, I reenter the dialog and it still reflects the old user/group ownership. If I chmod -R the /mnt/drive for my volume, there is no error message from the command, but it does not have any affect - the directory and files are still root/wheel.
I presume this permissions problem is why I cannot create the CIFS mount (which is my main problem) - when I use the UI to browse to select the mount, it is not listed as an option. I can manually enter the path, but I get permissions issue - I'm thinking the problem is upstream in the instructions (i.e. my unable to set permissions issue).
Any thoughts?
Thanks!
