HTAA_checkPassword(username,password,passwdfile)opens the password file, and checks if
the username-password pair is correct. Return value is YES, if and only if they are
correct. Otherwise, and also if the open fails, returns NO.
If the given password file name is NULL or an empty string, the default password file
name is used (macro PASSWD_FILE).

** NOTE:
** Uses currently the C library function crypt(), which
** only accepts at most 8 characters long strings and produces
** always 13 characters long strings. This function is
** called repeatedly so that longer strings can be encrypted.
** This is of course not as safe as encrypting the entire

** about the security inside the machine.
