Detailed Description

The QAuthenticator class is usually used in the authenticationRequired() and proxyAuthenticationRequired() signals of QNetworkAccessManager and QAbstractSocket . The class provides a way to pass back the required authentication information to the socket when accessing services that require authentication.

QAuthenticator supports the following authentication methods:

• Basic

• NTLM version 2

• Digest-MD5

• SPNEGO/Negotiate

Options

In addition to the username and password required for authentication, a QAuthenticator object can also contain additional options. The options() function can be used to query incoming options sent by the server; the setOption() function can be used to set outgoing options, to be processed by the authenticator calculation. The options accepted and provided depend on the authentication type (see method()).

The following tables list known incoming options as well as accepted outgoing options. The list of incoming options is not exhaustive, since servers may include additional information at any time. The list of outgoing options is exhaustive, however, and no unknown options will be treated or sent back to the server.

Basic

Option	Direction	Type	Description
realm	Incoming	QString	Contains the realm of the authentication, the same as realm()

The Basic authentication mechanism supports no outgoing options.

NTLM version 2

The NTLM authentication mechanism currently supports no incoming or outgoing options. On Windows, if no user has been set, domain\user credentials will be searched for on the local system to enable Single-Sign-On functionality.

Digest-MD5

Option	Direction	Type	Description
realm	Incoming	QString	Contains the realm of the authentication, the same as realm()

The Digest-MD5 authentication mechanism supports no outgoing options.

SPNEGO/Negotiate

Option	Direction	Type	Description
spn	Outgoing	QString	Provides a custom SPN.

This authentication mechanism currently supports no incoming options.

The spn property is used on Windows clients when an SSPI library is used. If the property is not set, a default SPN will be used. The default SPN on Windows is HTTP/<hostname>.

Other operating systems use GSSAPI libraries. For that it is expected that KDC is set up, and the credentials can be fetched from it. The backend always uses HTTPS@<hostname> as an SPN.

class PySide6.QtNetwork.QAuthenticator

PySide6.QtNetwork.QAuthenticator(other)

Parameters:

other – PySide6.QtNetwork.QAuthenticator

Constructs an empty authentication object.

Constructs a copy of other.

PySide6.QtNetwork.QAuthenticator.isNull()

Return type:

bool

Returns true if the object has not been initialized. Returns false if non-const member functions have been called, or the content was constructed or copied from another initialized QAuthenticator object.

PySide6.QtNetwork.QAuthenticator.__ne__(other)

Parameters:

other – PySide6.QtNetwork.QAuthenticator

Return type:

bool

Returns true if this authenticator is different from other; otherwise returns false.

PySide6.QtNetwork.QAuthenticator.__eq__(other)

Parameters:

other – PySide6.QtNetwork.QAuthenticator

Return type:

bool

Returns true if this authenticator is identical to other; otherwise returns false.

PySide6.QtNetwork.QAuthenticator.option(opt)

Parameters:

opt – str

Return type:

object

Returns the value related to option opt if it was set by the server. See the Options section for more information on incoming options. If option opt isn’t found, an invalid QVariant will be returned.
