Looks like you are hitting problems with older version of cifs-utils.

I ran the "mount -a" tests on openSUSE 11.4 and SLES11 SP1 but I could
reproduce this problem. I don't have a SLES11 setup. I'll see if I could
get one. Some useful information that'll help include

a) version of cifs-utils/cifs-mount
b) version of util-linux
c) mount -a -vvv output


OTOH, if you have a support contract with SUSE/Novell, please open a bug
report on https://bugzilla.novell.com agaist the product and include me
in the Cc.
