That shouldn't matter unless you're calling mount.cifs
directly. /bin/mount can handle this format. Also, if that were the case,
I wouldn't think that the mount helper would even get around to calling
mount().

Do you even have a /sbin/mount.cifs program? If not, that may be the
problem. If you do, maybe run this under strace so we can see what's
actually being passed to the kernel. Something like:

# strace -f -s 256 /bin/mount -t cifs //zang/s$ /mnt/zangshare -o user=foo,pass=bar

...and then find the mount() syscall in the output and send that here.
