### __init__(self, password_manager) (Constructor) | source code
Initialize a DigestMD5ServerAuthenticator object. Parameters: `password_manager` (: PasswordManager) - : name of the password manager object providing authentication credential verification. Overrides: core.ServerAuthenticator.__init__

### start(self, response) | source code
Start the authentication process. Parameters: `response` (: `str`) - : the initial response from the client (empty for DIGEST-MD5). Returns: sasl.Challenge, sasl.Success or sasl.Failure a challenge, a success indicator or a failure indicator. Overrides: core.ServerAuthenticator.start

### response(self, response) | source code
Process a client reponse. Parameters: `response` (: `str`) - : the response from the client. Returns: sasl.Challenge, sasl.Success or sasl.Failure a challenge, a success indicator or a failure indicator. Overrides: core.ServerAuthenticator.response

### _parse_response(self, response) | source code
Parse a client reponse and pass to further processing. Parameters: `response` (: `str`) - : the response from the client. Returns: sasl.Challenge, sasl.Success or sasl.Failure a challenge, a success indicator or a failure indicator.

### _check_params(self, username, realm, cnonce, digest_uri, response_val, authzid, nonce_count) | source code
Check parameters of a client reponse and pass them to further processing. Parameters: `username` (: `str`) - : user name. `realm` (: `str`) - : realm. `cnonce` (: `str`) - : cnonce value. `digest_uri` (: `str`) - : digest-uri value. `response_val` (: `str`) - : response value computed by the client. `authzid` (: `str`) - : authorization id. `nonce_count` (: `int`) - : nonce count value. Returns: sasl.Challenge, sasl.Success or sasl.Failure a challenge, a success indicator or a failure indicator.

### _make_final_challenge(self, username, realm, cnonce, digest_uri, response_val, authzid, nonce_count) | source code
Send the second challenge in reply to the client response. Parameters: `username` (: `str`) - : user name. `realm` (: `str`) - : realm. `cnonce` (: `str`) - : cnonce value. `digest_uri` (: `str`) - : digest-uri value. `response_val` (: `str`) - : response value computed by the client. `authzid` (: `str`) - : authorization id. `nonce_count` (: `int`) - : nonce count value. Returns: sasl.Challenge, sasl.Success or sasl.Failure a challenge, a success indicator or a failure indicator.
