Thanks for this post. The temp file workaround got me started. I didn't have to map a path to all the files I wanted, just /mnt/user/appdata/FreeRADIUS/raddb/:etc/freeradius/ In fact it may have been better if my unraid directory was also named raddb to match, but I don't feel like changing it now. Part of the issue may be that /etc/raddb is a symlink to //etc/freeradius in the most recent image.
