Space in credentials file, smbfs & fstab

Question

I'm trying to mount a Windows share on an Ubuntu Server box. It works with smbmount, and with an entry in /etc/fstab.

//Kubrick/Projects    /mnt/projects    smbfs    user=Eric\040Fritz%{pass},rw    0    0

However, when I try to write a credentials file, it always give me a "Permission Denied" error when I try to mount /mnt/projects. Here is the creds file and the new fstab line.

username=Eric Fritz
password={pass}

.

//Kubrick/Projects    /mnt/projects    smbfs    credentials=/root/.creds,rw    0    0

What is the proper way to escape the space in the username when using a credentials file?
