	long enough to be difficult to crack but short
	enough for users to remember without writing
	it down. This attribute is set to 8 by default.
passwordMaxRepeats	This attribute set the maximum number of
	times that the same character can be used in
	row, such as aaaaa. Setting the attribute to 0

	a character can be repeated. This attribute is
	set to 0 by default.
passwordMinAlphas	This attribute sets the minimum number of
	alphabetic chracters that must be used in the
	password. This setting does not set any

	for the minimum number of lowercase and
	uppercase letters are set in the

	attribute is set to 0, meaning there is no
	required minimum.

	numeric characters (0 through 9) which must
	be used in the password. By default, this
	attribute is set to 0, meaning there is no
	required minimum.

	special ASCII characters, such as !@#$.,
	which must be used in the password. By
	default, this attribute is set to 0, meaning
	there is no required minimum.

	lower case alphabetic characters, a to z,
	which must be used in the password. By
	default, this attribute is set to 0, meaning
