enum SignOn::AuthSession::AuthSessionError

Codes for errors that may be reported by AuthSession objects.

Deprecated:
  This enum is deprecated. Replaced by Error::ErrorType.

Enumerator
UnknownError | Catch-all for errors not distinguished by another code.
InternalServerError | Signon Daemon internal error.
InternalCommunicationError | Communication with Signon Daemon error .
PermissionDeniedError | The operation cannot be performed due to insufficient client permissions.
MechanismNotAvailableError | The requested mechanism is not available.
MissingDataError | The SessionData object does not contain necessary information.
InvalidCredentialsError | The supplied credentials are invalid for the mechanism implementation.
WrongStateError | An operation method has been called in a wrong state.
OperationNotSupportedError | The operation is not supported by the mechanism implementation.
NoConnectionError | No Network connetion.
NetworkError | Network connetion failed.
SslError | Ssl connetion failed.
RuntimeError | Casting SessionData into subclass failed

Definition at line 69 of file authsession.h.

enum SignOn::AuthSession::AuthSessionState

Codes for the states of the AuthSession object.

See Also
  stateChanged(AuthSession::AuthSessionState state, const QString &message)

Todo:
  The order of the states must be synchronized with AuthPluginState enum

Enumerator

ReplyWaiting | Waiting reply from remote server.
UserPending | Waiting response from user.
UiRefreshing | Refreshing ui request.
ProcessPending | Waiting another process to start.

ProcessCanceling | Canceling.current process: is this really needed???
ProcessDone | Authentication completed. >
CustomState | Custom message.

Definition at line 95 of file authsession.h.

## Constructor & Destructor Documentation

SignOn::AuthSession::AuthSession | ( | quint32 | id,
|  | const QString & | methodName,
|  | QObject * | parent = `0`
| ) |  |
| protected

Definition at line 34 of file authsession.cpp.

## Member Function Documentation

void SignOn::AuthSession::cancel | ( |  | ) |

Cancels the ongoing challenge.

Signal error() is emitted with Error::type() Error::SessionCanceled when process is canceled. If there is no challenge to cancel, Error::type() is Error::WrongState. If the operation fails, the error() signal is emitted.

See Also
  AuthSession::error()

Definition at line 73 of file authsession.cpp.

void SignOn::AuthSession::challenge | ( | const SessionData & | sessionData,
|  | const QString & | mechanism = `QString()`
| ) |  |
| inline

Sends a challenge to the authentication service.

The service processes the challenge and generates a response token that is emitted with response() signal. If the operation fails, the error() signal is emitted.

This is actually a call to process.

See Also
  process
  AuthSession::response()
  AuthSession::error()

Parameters

  sessionData | Information for authentication session
  mechanism | Mechanism to use for authentication

Definition at line 183 of file authsession.h.

void SignOn::AuthSession::error | ( | const SignOn::Error & | err | ) |
| signal

Emitted when an error occurs while performing an operation.

Typical error types are generic errors, where Error::type() < Error::AuthServiceErr and AuthSession specific, where Error::AuthSessionErr < Error::type() < Error::UserErr

See Also
  SignOn::Error
  SignOn::Error::ErrorType

Parameters

  err | The error object

void SignOn::AuthSession::mechanismsAvailable | ( | const QStringList & | mechanisms | ) |
| signal

Emitted when the list of available mechanisms have been obtained for identity.

Parameters

  mechanisms | List of available mechanisms

const QString SignOn::AuthSession::name | ( |  | ) | const

Name of method for session.

Returns
  Name of authentication method.

Definition at line 57 of file authsession.cpp.

void SignOn::AuthSession::process | ( | const SessionData & | sessionData,
|  | const QString & | mechanism = `QString()`
| ) |  |

Processes sessionData in the authentication service.

The service processes the data and generates a response that is emitted with response() signal. If the operation fails, the error() signal is emitted.

The format and interpretation of the data is mechanism-specific. The client usually obtains the data from a network protocol, such as the protocols using SASL. In case the mechanism implies generation of the authentication token without a challenge, this method should be called with an empty parameters.

Parameters are key value pairs, and they are given for authentication plugin. For example it can contain server name, realm, client key, etc. If the Identity objected that created this AuthSession object was itself created using a IdentityInfo object having the username and secret set, that data is going to be added to the params map before it is passed to a specific authentication plugin implementation. If credentials have been stored with Identity::storeCredentials, then the username is overriden from database. Stored secret is used as a default value.

See Also
  AuthSession::response()
  AuthSession::error()

Parameters

  sessionData | Information for authentication session
  mechanism | Mechanism to use for authentication

See Also
  IdentityInfo
  AuthPluginInterface

Definition at line 67 of file authsession.cpp.

void SignOn::AuthSession::queryAvailableMechanisms | ( | const QStringList & | wantedMechanisms = `QStringList()` | ) |

Query list of available mechanisms.

If wantedMechanisms list is provided, only mechanisms available on that list are reported. List is returned by emitting signal mechanismsAvailable(). If the operation fails, the error() signal is emitted.

See Also
  AuthSession::mechanismsAvailable()
  AuthSession::error()

Parameters

  wantedMechanisms | List of mechanisms that the client would like to use

Definition at line 62 of file authsession.cpp.

void SignOn::AuthSession::request | ( | const SessionData & | sessionData,
|  | const QString & | mechanism = `QString()`
| ) |  |
| inline

Sends a request to the authentication service.

The service processes the request and generates a response token that is emitted with response() signal. If the operation fails, the error() signal is emitted.

This is actually a call to process.

See Also
  process
  AuthSession::response()
  AuthSession::error()

Parameters

  sessionData | Information for authentication session
  mechanism | Mechanism to use for authentication

Definition at line 201 of file authsession.h.

void SignOn::AuthSession::response | ( | const SignOn::SessionData & | sessionData | ) |
| signal

Authentication response generated by the authentication service.

It is sent after a process() call sends a challenge token for authentication is used to request an authentication token, with the response token and accompanying non-opaque information produced by the service.

The format and interpretation of the response, as well as names and types of the information parameters, are mechanism-specific.

Parameters

  sessionData | Parameters with the authentication token

void SignOn::AuthSession::signMessage | ( | const SessionData & | params,
|  | const QString & | mechanism = `QString()`
| ) |  |
| inline

Signs message by using secret stored into identity.

This convenience interface is to do special challenge to signature service.

Parameters

  params | Extra information for signing
  mechanism | Mechanism to use for signing

Deprecated:

Definition at line 224 of file authsession.h.

void SignOn::AuthSession::stateChanged | ( | AuthSession::AuthSessionState | state,
|  | const QString & | message
| ) |  |
| signal

Provides the information about the state of the authentication request.

Parameters

  state | Current state of the authentication request
  message | Textual description of the state
