The bug description includes dmesg output demonstrating the issue is
real; comment #6 includes the kernel source that probably emitted the
logs in the description. Thus setting to 'confirmed'.

Title:
  unable to mount CIFS share with comma in password

Status in cifs-utils package in Ubuntu:
  Confirmed
Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Since the update to Quantal I am unable to mount CIFS shares with a
  comma in the password:

  root@lama ~ # PASSWD=",password" mount -t cifs //cifs.example.org target -o username=user,domain=dom,uid=4711,gid=12345
  mount error(22): Invalid argument
  Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
  32 root@lama ~ # dmesg | tail -1
  [17848.954253] CIFS: Unknown mount option "password"

  The same thing happens with a credential file and the password prompt.

  This looks like a parser regression:
  mount.cifs(8) explains:
             Note that a password which contains the delimiter character (i.e. a
             comma ´,´) will fail to be parsed correctly on the command line.
             However, the same password defined in the PASSWD environment
             variable or via a credentials file (see below) or entered at the
             password prompt will be read correctly.

  This is pretty evil, as it exposes parts of the password through
  dmesg.
