The "Authen::CyrusSASL" module
    provides a simple class that allows you to send request to the cyrus-sasl's
    2.0 authen daemon. This module is based on the Authen::Radius module with
    the similar interface.
  - new ( Type => < SASL_AUTHD
    | SASL_PWCHECK >, < Dir => dirpath | Path => sockpath > [,
    TimeOut => TIMEOUT] )
- Creates & returns a blessed reference to a Authen::CyrusSASL object,
      or undef on failure. Error is saved into $!. Use undef on the return value
      if you want to undef the underlying unix socket.
    There are two types for Type attribute - one for saslauth
        daemon and one for old pwcheck daemon (SASL_PWCHECK). The Type attribute
        is obligatory. The default value for Dir is '/var/run/pwcheck' (it then looks
        for the path '/var/run/pwcheck/pwcheck') for pwcheck method, and
        '/var/run/saslauthd' (path '/var/run/saslauthd/mux') for saslauthd
        method. You can specify the full path for pwcheck or mux special files
        with the Path attribute. The TimeOut value is self explonatory. 
  - check_pwd (
    USERNAME, PASSWORD, SERVICE, REALM )
- Checks with the SASL server if the specified
      "PASSWORD" is valid for user
      "USERNAME". It returns SASL_OK if the
      "PASSWORD" is correct, SASL_FAIL if the
      connection fails, or SASL_BADAUTH if the password or the username is
      incorrect (possible error is in the $! variable).
