I also had this problem, and discovered that somehow my mount point had become owned by root, despite it being in my user’s home directory, and created by the user. Not sure how the permissions had been changed, but changed them back to the user again and all was well.

Good point. Actually, isn’t this the expected behavior? Every time I set up a read/write mount point outside of /home I usually chown it so that I’m the owner. It might not be best practice, but it doesn’t hurt.
I don’t think the the rw,user option in fstab overrides the normal file permission on your mount point directory, but I might be wrong…

Unfortunately it didn’t work for me; I got

mount error: permission denied or not superuser and mount.cifs not installed SUID

I too had this problem
You have to set the right owner for the mount point

for example, about the command:

//server/share /mnt cifs rw,user,noauto,username=user,password=pass 0 0

/mnt has to be owned by user:user_group

ps. remember to add suid to umount.cifs too

[…] First you will need to mount the network share on your box. Next you will need the Spreadsheet::ParseExcel package from CPAN. […]

Korinthe – do you get that message when mounting or when trying to do the chmod?

Do the chmod as root and then mount. That may fix the issue here.

Either that or you don’t have mount.cifs installed. See if it exists in your /sbin directory:

ls /sbin | grep cifs

If it’s not there you probably will need to instal the smbfs package. On redhat that should be possible via yum no?

Unfortunately it didn’t work for me; I got

Yup, Mookie’s suggestion worked for me too.

THX Mookie!
I had the same problem and this fixed it!

As root: chmod +s /sbin/mount.cifs
