<p>You cannot use the credentials file for passwords containing special characters like "." or ",".</p>
<blockquote>
<p>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) will be
read correctly.</p>

<p>A solution would be to set up an environment variable for this share. The <code>mount</code> command will use this password and special characters are allowed.</p>
<p>I haven't read of escaping special characters in the credentials file.</p>
