## Known Implementations

TpSvcChannelTypeServerAuthentication is implemented by TpBasePasswordChannel.

TpSvcChannelInterfaceSASLAuthentication is implemented by TpBasePasswordChannel.

## Includes

    #include <telepathy-glib/telepathy-glib-dbus.h>

## Description

The ServerAuthentication channel type represents a request for client/UI processes to carry out authentication with a server.

The SASLAuthentication interface allows authentication via SASL, and also allows providing a simple password to the connection manager for it to use with SASL or non-SASL mechanisms.

The CaptchaAuthentication interface (since 0.17.5) allows interactive captcha-solving so that the user can prove that they are not a bot, on protocols requiring this.

## Types and Values

### TpSvcChannelTypeServerAuthentication

    typedef struct _TpSvcChannelTypeServerAuthentication TpSvcChannelTypeServerAuthentication;

Dummy typedef representing any implementation of this interface.

### TpSvcChannelTypeServerAuthenticationClass

    typedef struct _TpSvcChannelTypeServerAuthenticationClass TpSvcChannelTypeServerAuthenticationClass;

The class of TpSvcChannelTypeServerAuthentication. This interface has no D-Bus methods, so an implementation can typically pass `NULL` to `G_IMPLEMENT_INTERFACE()` as the interface initialization function.

### TpSvcChannelInterfaceSASLAuthentication

    typedef struct _TpSvcChannelInterfaceSASLAuthentication TpSvcChannelInterfaceSASLAuthentication;

Dummy typedef representing any implementation of this interface.

### TpSvcChannelInterfaceSASLAuthenticationClass

    typedef struct _TpSvcChannelInterfaceSASLAuthenticationClass TpSvcChannelInterfaceSASLAuthenticationClass;

The class of TpSvcChannelInterfaceSASLAuthentication.

In a full implementation of this interface (i.e. all methods implemented), the interface initialization function used in `G_IMPLEMENT_INTERFACE()` would typically look like this:

    static void
    implement_channel_interface_sasl_authentication (gpointer klass,
        gpointer unused G_GNUC_UNUSED)
    {
    #define IMPLEMENT(x) tp_svc_channel_interface_sasl_authentication_implement_##x (\
      klass, my_object_##x)
      IMPLEMENT (start_mechanism);
      IMPLEMENT (start_mechanism_with_data);
      IMPLEMENT (respond);
      IMPLEMENT (accept_sasl);
      IMPLEMENT (abort_sasl);
    #undef IMPLEMENT
    }

### TpSvcChannelInterfaceCaptchaAuthentication

    typedef struct _TpSvcChannelInterfaceCaptchaAuthentication TpSvcChannelInterfaceCaptchaAuthentication;

Dummy typedef representing any implementation of this interface.

### TpSvcChannelInterfaceCaptchaAuthenticationClass

    typedef struct _TpSvcChannelInterfaceCaptchaAuthenticationClass TpSvcChannelInterfaceCaptchaAuthenticationClass;

The class of TpSvcChannelInterfaceCaptchaAuthentication.

In a full implementation of this interface (i.e. all methods implemented), the interface initialization function used in `G_IMPLEMENT_INTERFACE()` would typically look like this:

    static void
    implement_channel_interface_captcha_authentication (gpointer klass,
        gpointer unused G_GNUC_UNUSED)
    {
    #define IMPLEMENT(x) tp_svc_channel_interface_captcha_authentication_implement_##x (\
      klass, my_object_##x)
      IMPLEMENT (get_captchas);
      IMPLEMENT (get_captcha_data);
      IMPLEMENT (answer_captchas);
      IMPLEMENT (cancel_captcha);
    #undef IMPLEMENT
    }

## Signal Details

### The `“new-challenge”` signal

    void
    user_function (TpSvcChannelInterfaceSASLAuthentication *self,
                   GArray_guchar_                          *arg_Challenge_Data,
                   gpointer                                 user_data)

The NewChallenge D-Bus signal is emitted whenever this GObject signal is.

#### Parameters

self | an object |
arg_Challenge_Data | const GArray * (FIXME, generate documentation) |
user_data | user data set when the signal handler was connected. |

Flags: Has Details

### The `“s-as-lstatus-changed”` signal

    void
    user_function (TpSvcChannelInterfaceSASLAuthentication *self,
                   guint                                    arg_Status,
                   gchar                                   *arg_Reason,
                   gpointer                                 user_data)

The SASLStatusChanged D-Bus signal is emitted whenever this GObject signal is.

#### Parameters

self | an object |
arg_Status | guint (FIXME, generate documentation) |
arg_Reason | const gchar * (FIXME, generate documentation) |
arg_Details | GHashTable * (FIXME, generate documentation) |
user_data | user data set when the signal handler was connected. |
