# Intent is to allow calls to mount with -t smb to work properly
# (either manually or from an automounter).
#
# bugs:
#  -- possible security hole, as this is a shell script called as root...
#  -- arguments other than rw and ro which mount might supply are not handled
#

#
# To use this from autofs:
#
# have an entry of the form
#	key	-fstype=smb,-Uadministrator,-Ppassword	://host/share
# in the appropriate /etc/auto.mountpoint file.
#
# This makes access to /mountpoint/key/ access smb //host/share/ 
# as administrator (or another user, if you specify such) with the given
# password.  You may have to supply a -c <unqualified-localhostname>.
# Special characters need to be 'escaped' with a backslash ('\') -- for 
# instance, if you want to use the default share names with a "$" at the 
# end (e.g., //host/c$), you must enter ://host/c\$ 
#
# Note that mount/autofs is smart enough to figure out how to unmount
# this without any extra work on our part!

#
# I get called in the form: /sbin/mount.smb //host/shr /mnt/tmp -o rw,arg1,arg2
#
# It looks like mount tacks on either "rw" or "ro" as the first argument,
# so I'm going to count on having exactly 5 arguments.
#
# This has been developed and tested with mount-2.7
