GNOME_VFS_MODULE_CALLBACK_FILL_AUTHENTICATION

#define GNOME_VFS_MODULE_CALLBACK_FILL_AUTHENTICATION "fill-authentication"

A module callback name used together with gnome_vfs_module_callback_invoke() to ask the keyring manager for login data. It is expected to return stored or cached login data, but may not query the user.

The login data consists of a username, a password and a domain, and is used to access a resource. If the data is not suitable for accessing the resource, the GnomeVFSModule typically issues a GNOME_VFS_MODULE_CALLBACK_FULL_AUTHENTICATION module callback to query the user right after the authentication failed.

`in arg` :	A GnomeVFSModuleCallbackFillAuthenticationIn * passed to the application, specifying the authentication request. The application will usually proxy this request to the keyring manager of the desktop environment, but it can also handle the request itself.
`out arg` :	A GnomeVFSModuleCallbackFillAuthenticationOut * passing the cached keyring data (i.e. username/password etc.) back to the module. Usually, this is data that was stored using GNOME_VFS_MODULE_CALLBACK_SAVE_AUTHENTICATION, and is either stored permanently on disk or cached.

GnomeVFSModuleCallbackFillAuthenticationIn

typedef struct {
	char *uri;
	char *protocol;
	char *server;
	char *object;
	int port;
	char *authtype;
	char *username;
	char *domain;
} GnomeVFSModuleCallbackFillAuthenticationIn;

A pointer to a GnomeVFSModuleCallbackFillAuthenticationIn structure is passed to the GNOME_VFS_MODULE_CALLBACK_FILL_AUTHENTICATION callback, and informs the application about the authentication parameters that should be requested from the user.

The GNOME_VFS_MODULE_CALLBACK_FILL_AUTHENTICATION application callback will then set the members of a pointer to a GnomeVFSModuleCallbackFillAuthenticationOut structure according to the stored or cached data.

Members

char *`uri`;	The textual URI of the resource that requires authentication.
char *`protocol`;	One of the protocols supported by the invoking module. Typically matches `uri` 's protocol.
char *`server`;	The server that contains the resource that requires authentication. Typically matches `uri` 's hostname.
char *`object`;	The type of the resource that requires authentication.
int `port`;	The port that was used to connect to `server` . 0 means unset.
char *`authtype`;	The type of authentication that was requested. For the HTTP method, this may be "basic" or "proxy". For the SFTP method, this may be "publickey" or "password".
char *`username`;	The username that was used to connect to `server` .
char *`domain`;	The domain that `server` belongs to (only used by the SMB method).

GnomeVFSModuleCallbackFillAuthenticationOut

typedef struct {
	gboolean valid;
	char *username;
	char *domain;
	char *password;
} GnomeVFSModuleCallbackFillAuthenticationOut;

A pointer to a GnomeVFSModuleCallbackFillAuthenticationOut structure is passed to the GNOME_VFS_MODULE_CALLBACK_FILL_AUTHENTICATION callback, and informs the module about the authentication parameters that were found in the cache or permanently stored.

The login data returned by GNOME_VFS_MODULE_CALLBACK_FILL_AUTHENTICATION was usually previously stored using #GNOME_VFS_MODULE_CALLBACK_SAVE_AUTHENTICATION.

Members

gboolean `valid`;	Whether stored or cached login data was found for the resource referenced by the GnomeVFSModuleCallbackFillAuthenticationIn structure.
char *`username`;	The cached username that should be used to access the resource. This will be freed by the module when it isn't needed any longer. May only be set if `valid` is `TRUE`.
char *`domain`;	The cached domain that should be used to access the resource. This will be freed by the module when it isn't needed any longer. May only be set if `valid` is `TRUE`.
char *`password`;	The cached password that should be used to access the resource. This will be freed by the module when it isn't needed any longer. May only be set if `valid` is `TRUE`.

GNOME_VFS_MODULE_CALLBACK_FULL_AUTHENTICATION

#define GNOME_VFS_MODULE_CALLBACK_FULL_AUTHENTICATION "full-authentication"

A module callback name used together with gnome_vfs_module_callback_invoke() to ask the user for login data. This includes username and password, but also special login choices like anonymous login.

`in arg` :	A GnomeVFSModuleCallbackFullAuthenticationIn * passed to the application, specifying the authentication request.
`out arg` :	A GnomeVFSModuleCallbackFullAuthenticationOut * passing the user's provided authentication data (i.e. his username/password etc.) back to the module.

enum GnomeVFSModuleCallbackFullAuthenticationFlags

These flags will be passed to the GNOME_VFS_MODULE_CALLBACK_FULL_AUTHENTICATION callback, as part of the GnomeVFSModuleCallbackFullAuthenticationIn structure. The output data will be stored in a GnomeVFSModuleCallbackFullAuthenticationOut structure.

Members

GNOME_VFS_MODULE_CALLBACK_FULL_AUTHENTICATION_PREVIOUS_ATTEMPT_FAILED	This is not the first login attempt, i.e. this callback was already invoked but the provided login data was not suitable for a successful login.
GNOME_VFS_MODULE_CALLBACK_FULL_AUTHENTICATION_NEED_PASSWORD	The application should ask the user for a password and set the `password` field of GnomeVFSModuleCallbackFullAuthenticationOut.
GNOME_VFS_MODULE_CALLBACK_FULL_AUTHENTICATION_NEED_USERNAME	The application should ask the user for a username and set the `username` field of GnomeVFSModuleCallbackFullAuthenticationOut.
GNOME_VFS_MODULE_CALLBACK_FULL_AUTHENTICATION_NEED_DOMAIN	The application should ask the user for a domain and set the `domain` field of GnomeVFSModuleCallbackFullAuthenticationOut.
GNOME_VFS_MODULE_CALLBACK_FULL_AUTHENTICATION_SAVING_SUPPORTED	The application may ask the user whether he wants to save the password. If this flag is not present, or the user does not want to save the password, the application must set the `save_password` field of GnomeVFSModuleCallbackFullAuthenticationOut to `FALSE` and its keyring field to `NULL`. If the `save_password` field is `TRUE`, the module invoking the GNOME_VFS_MODULE_CALLBACK_FULL_AUTHENTICATION callback is expected to invoke the GNOME_VFS_MODULE_CALLBACK_SAVE_AUTHENTICATION callback if the login attempt was successful with the `username` , `password` , `domain` and `keyring` fields of GnomeVFSModuleCallbackFullAuthenticationOut.
GNOME_VFS_MODULE_CALLBACK_FULL_AUTHENTICATION_ANON_SUPPORTED	The application should offer the user a choice to login anonymously (used for example by the FTP module). If the user requests anonymous login, GNOME_VFS_MODULE_CALLBACK_FULL_AUTHENTICATION_OUT_ANON_SELECTED must be set in the `out_flags` field of GnomeVFSModuleCallbackFullAuthenticationOut.

GnomeVFSModuleCallbackFullAuthenticationIn

typedef struct {
	GnomeVFSModuleCallbackFullAuthenticationFlags flags;

	char *uri;
	char *protocol;

	/* for pre-filling the dialog */
	char *default_user;     
	char *default_domain;
} GnomeVFSModuleCallbackFullAuthenticationIn;

A pointer to a GnomeVFSModuleCallbackFullAuthenticationIn structure is passed to the GNOME_VFS_MODULE_CALLBACK_FULL_AUTHENTICATION callback, and informs the application about the authentication parameters that should be requested from the user.

The GNOME_VFS_MODULE_CALLBACK_FULL_AUTHENTICATION application callback will then set the members of a pointer to a GnomeVFSModuleCallbackFullAuthenticationOut structure according to the user input.

Members

GnomeVFSModuleCallbackFullAuthenticationFlags `flags`;	GnomeVFSModuleCallbackFullAuthenticationFlags influencing the user query.
char *`uri`;	The textual URI of the resource that requires authentication.

char *`server`;	The server that contains the resource that requires authentication. Typically matches `uri` 's hostname.
char *`object`;	The type of the resource that requires authentication.
int `port`;	The port that was used to connect to `server` . 0 means unset.
char *`authtype`;	The type of authentication that was requested. For the HTTP method, this may be "basic" or "proxy". For the SFTP method, this may be "publickey" or "password".
char *`username`;	The username that was used to connect to `server` . This variable should just be used for display purposes, i.e. like “You were trying to access foo`bar.com` ” where foo is the `username` and bar.com is the `server` . Do not make the contents of the GnomeVFSModuleCallbackFullAuthenticationOut output variables depend on the value of this variable. If you want to handle absence of user input, pass back `default_user` instead.
char *`domain`;	The domain that `server` belongs to (only used by the SMB method). This variable should just be used for display purposes where foo is the `username` and bar.com is the `server` . Do not make the contents of the GnomeVFSModuleCallbackFullAuthenticationOut output variables depend on the value of this variable. If you want to handle absence of user input, pass back `default_domain` instead.
char *`default_user`;	The username that should be provided to the user by default. Typically matches `username` .
char *`default_domain`;	The domain that should be provided to the user by default. Typically matches `domain` .

} GnomeVFSModuleCallbackFullAuthenticationOut;

A pointer to a GnomeVFSModuleCallbackFullAuthenticationOut structure is passed to the GNOME_VFS_MODULE_CALLBACK_FULL_AUTHENTICATION callback, and informs the module about the authentication parameters that the user provided by setting the respective fields according to the user input and the passed-in GnomeVFSModuleCallbackFullAuthenticationIn pointer.

Members

gboolean `abort_auth`;	Whether the user somehow cancelled the login process. The application is expected to offer the user a cancellation point during the authentication query. In a graphical user interface, this is typically achieved by providing a "Cancel" button.
char *`username`;	The user-provided username that should be used to access the resource referenced by GnomeVFSModuleCallbackFullAuthenticationIn. This will be freed by the module when it isn't needed any longer. Must not be set if the GnomeVFSModuleCallbackFullAuthenticationFlags don't contain GNOME_VFS_MODULE_CALLBACK_FULL_AUTHENTICATION_NEED_USERNAME.
char *`domain`;	The user-provided domain that should be used to access the resource referenced by GnomeVFSModuleCallbackFullAuthenticationIn. This will be freed by the module when it isn't needed any longer. Must not be set if the GnomeVFSModuleCallbackFullAuthenticationFlags don't contain GNOME_VFS_MODULE_CALLBACK_FULL_AUTHENTICATION_NEED_DOMAIN.
char *`password`;	The user-provided password that should be used to access the resource referenced by GnomeVFSModuleCallbackFullAuthenticationIn. This will be freed by the module when it isn't needed any longer. Must not be set if the GnomeVFSModuleCallbackFullAuthenticationFlags don't contain GNOME_VFS_MODULE_CALLBACK_FULL_AUTHENTICATION_NEED_PASSOWRD.

This will later be passed to the GNOME_VFS_MODULE_CALLBACK_SAVE_AUTHENTICATION callback if the login attempt was successful with the specified `username` , `password` and `domain` . This will NOT be freed by the module, so the application typically provides a `NULL` pointer or a pointer to a static string.
gsize `out_flags`;	GnomeVFSModuleCallbackFullAuthenticationOutFlags signalling a special request, for instance anonymous access to an FTP server.
