This only implements non-SASL authentication, per U{JEP-0078<http://www.jabber.org/jeps/jep-0078.html>}. Additionally, this authenticator provides the ability to perform inline registration, per U{JEP-0077<http://www.jabber.org/jeps/jep-0077.html>}. Under normal circumstances, the BasicAuthenticator generates the L{xmlstream.STREAM_AUTHD_EVENT} once the stream has authenticated. However, it can also generate other events, such as: - L{INVALID_USER_EVENT} : Authentication failed, due to invalid username - L{AUTH_FAILED_EVENT} : Authentication failed, due to invalid password - L{REGISTER_FAILED_EVENT} : Registration failed If authentication fails for any reason, you can attempt to register by calling the L{registerAccount} method. If the registration succeeds, a L{xmlstream.STREAM_AUTHD_EVENT} will be fired. Otherwise, one of the above errors will be generated (again). @cvar INVALID_USER_EVENT: See L{IQAuthInitializer.INVALID_USER_EVENT}. @type INVALID_USER_EVENT: L{str} @cvar AUTH_FAILED_EVENT: See L{IQAuthInitializer.AUTH_FAILED_EVENT}. @type AUTH_FAILED_EVENT: L{str} @cvar REGISTER_FAILED_EVENT: Token to signal that registration failed. @type REGISTER_FAILED_EVENT: L{str} r z'//event/client/basicauth/registerfailedc C s t j�| |j� || _|| _d S r )r �ConnectAuthenticatorr �hostr rC )r r rC r r r r � s zBasicAuthenticator.__init__c C s0 d|_ tj�| |� tj|dd�t|�g|_d S )N)r r F��required)�versionr rV �associateWithStream�TLSInitiatingInitializerr- � initializersr0 r r r r[ � s �z&BasicAuthenticator.associateWithStreamNc C sj |r|| j _|r || _t| jd�}|�d� |jjd| j jd� |jjd| jd� |�| j� |� � d S )Nr )zjabber:iq:registerr5 r6 r7 rC ) r r; rC r r r9 r5 r �_registerResultEventr& )r r6 rC r r r r �registerAccount� s z"BasicAuthenticator.registerAccountc C s, |d dkr | � � d S | j�|| j� d S )Nr �result)� streamStartedr rP �REGISTER_FAILED_EVENTr( r r r r^ � s z'BasicAuthenticator._registerResultEvent)NN) r) r* r+ r, � namespacer- rR rS rb r r[ r_ r^ r r r r r � s r c @ s e Zd ZdZdd� Zdd� ZdS )�CheckVersionInitializerzU Initializer that checks if the minimum common stream version number is 1.0. c C r. r r/ r0 r r r r � r2 z CheckVersionInitializer.__init__c C s | j jdk r t�d��d S )N)� r zunsupported-version)r rZ r � StreamError)r r r r r@ � s �z"CheckVersionInitializer.initializeN)r) r* r+ r, r r@ r r r r rd � s rd c @ s( e Zd ZdZedfZdd� Zdd� ZdS )�BindInitializerz� Initializer that implements Resource Binding for the initiating entity.

This authenticator performs the initialization steps needed to start exchanging XML stanzas with an XMPP server as an XMPP client. It checks if the server advertises XML stream version 1.0, negotiates TLS (when available), performs SASL authentication, binds a resource and establishes a session. Upon successful stream initialization, the L{xmlstream.STREAM_AUTHD_EVENT} event will be dispatched through the XML stream object. Otherwise, the L{xmlstream.INIT_FAILED_EVENT} event will be dispatched with a failure object. After inspection of the failure, initialization can then be restarted by calling L{ConnectAuthenticator.initializeStream}. For example, in case of authentication failure, a user may be given the opportunity to input the correct password. By setting the L{password} instance variable and restarting initialization, the stream authentication step is then retried, and subsequent steps are performed if successful. @ivar jid: Jabber ID to authenticate with. This may contain a resource part, as a suggestion to the server for resource binding. A server may override this, though. If the resource part is left off, the server will generate a unique resource identifier. The server will always return the full Jabber ID in the resource binding step, and this is stored in this instance variable. @type jid: L{jid.JID} @ivar password: password to be used during SASL authentication. @type password: L{unicode} r Nc C s& t j�| |j� || _|| _|| _dS )a3 @param configurationForTLS: An object which creates appropriately configured TLS connections.
