Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Despite the presence of auto and the permissive settings of timeo and retry, the mount does not happen at boot time:
pwa@suillus:~> mount | grep hp
Furthermore, despite the presence of users, (I also tried user), an ordinary user can't do the mount:
pwa@suillus:~> mount /mediavault
mount: hpmediavault:/shares/Volume1/FileShare failed, reason given by server: Permission denied
pwa@suillus:~> mount /musicvault
mount: hpmediavault:/shares/Volume1/MediaShare failed, reason given by server: Permission denied
However, root can do it:
pwa@suillus:~> sudo mount -a
pwa@suillus:~> mount | grep hp
hpmediavault:/shares/Volume1/FileShare on /mediavault type nfs (rw,users,noexec,nosuid,nodev,rsize=8192,wsize=8192,timeo=30,retry=5,addr=192.168.0.104)
hpmediavault:/shares/Volume1/MediaShare on /musicvault type nfs (rw,users,noexec,nosuid,nodev,rsize=8192,wsize=8192,timeo=30,retry=5,addr=192.168.0.104)
Here is the description of auto from the mount man page:
Can be mounted with the -a option.
(The mount at boot time is done with mount -a, I believe.)
And here is the description of users from that man page:
Allow every user to mount and unmount the file system. This option implies the options noexec, nosuid, and nodev (unless overridden by subsequent options, as in the option line users,exec,dev,suid).
So what am I missing?

Reason: Reference the OS I'm using.

Networking more than likely has not started yet before running the fstab file.
Change the auto to noauto so it will not be trying to mount yet.
Now not a Suse user but would say there is some knid of script that is started near the end of the boot process. In that add you mount -a command.
In Redhat type distros there is /etc/rc.local script.
Only root can use the mount command unless you let others through sudo.
It seems that an ordinary user can actually issue the mount command, since it works perfectly well without parameters and gives the mount status. I was able to use user in /etc/fstab in the previous version of OpenSuSE (10.2) and there an ordinary user was able to do the mount.
As to noauto: specifying it means that mount -a won't work at all, so there's a loss of functionality in doing that. Nevertheless I can still follow your suggestion about inserting mount -a in one of the init scripts. But as I read the manual, the mount is retried until it times out (which I don't think it does), so it should happen after a while anyway. And it doesn't.
Bugzilla at Novell reports that the problem with user not working is a bug, which can be fixed by setting the suid bit for mount.nfs. It hasn't been fixed yet because of security issues, but it's set in Kubuntu.
The situation with auto is less clear. Others have reported the problem, but it hasn't been pinned down yet.
