Transmission client can't access mounted NFS share

view story

http://unix.stackexchange.com – I set up transmission-daemon on my Scientific Linux 6.3 machine to download files to a mounted NFS share (mounted during boot via /etc/fstab). The directory that the NFS share is mounted to was chown'ed to the transmission-daemon user and group. In the Transmission web interface, I add a test .torrent file, and got a permission denied error when Transmission tries to access the destination download directory (i.e the mounted NFS share). However, a regular user on the SL 6.3 system can read and write to that share fine. What should I do to resolve this issue? Thanks. (HowTos)
