Detailed Description

Authorization Callouts.

The GSI Authorization API provides an interface for making generic authorization decisions using dynamically-loaded authorization modules. The API documentation is divided into the following sections:

• GSI Authorization API
• GSI Credential Constants

Function Documentation

globus_gsi_authorize()

globus_result_t globus_gsi_authorize	(	globus_gsi_authz_handle_t	handle,
		const void *	action,
		const void *	object,
		globus_gsi_authz_cb_t	callback,
		void *	callback_arg
	)

Start the authorization decision-making process.

Processes an authorization decision by calling the GLOBUS_GSI_AUTHORIZE_ASYNC function named in the authorization configuration file. The parameters to this function are passed to the authorization callout. Once the authorization decision is made, the callback function will be called, with the result and the callback_arg passed to it.

Parameters

handle	Pointer to an authorization handle
action	Action to authorize
object	Object that the action pertains to.
callback	Callback function to call when authorization completes
callback_arg	Argument to callback function

Returns

GLOBUS_SUCCESS if successful, or a Globus error object on failure.

globus_gsi_authz_get_authorization_identity()

globus_result_t globus_gsi_authz_get_authorization_identity	(	globus_gsi_authz_handle_t	handle,
		char **	identity_ptr,
		globus_gsi_authz_cb_t	callback,
		void *	callback_arg
	)

Query for authorization identity.

Query for authorization identity by calling the GLOBUS_GSI_GET_AUTHORIZATION_IDENTITY callout.

Parameters

handle	The handle that is to be used for the identity check.
identity_ptr	The authorization identity determined by the authorization handle. This is must be freed by the caller. If the value is NULL (and this function returned GLOBUS_SUCCESS), the caller should use the authenticated identity.
callback	Callback function to call when identity is determined.
callback_arg	Argument to callback function.

Returns

GLOBUS_SUCCESS

globus_gsi_authz_handle_destroy()

globus_result_t globus_gsi_authz_handle_destroy	(	globus_gsi_authz_handle_t	handle,
		globus_gsi_authz_cb_t	callback,
		void *	callback_arg
	)

Destroy an authz handle.

Initialize an authorization handle by calling the GLOBUS_GSI_AUTHZ_HANDLE_DESTROY function named in the authorization configuration file. Once the initialization is complete, the callback function is called, with the result and the callback_arg passed to it.

Parameters

handle	The handle that is to be destroyed
callback	Callback function to call when handle is destroyed
callback_arg	Argument to callback function

Returns

GLOBUS_SUCCESS

globus_gsi_authz_handle_init()

globus_result_t globus_gsi_authz_handle_init	(	globus_gsi_authz_handle_t *	handle,
		const char *	service_name,
		const gss_ctx_id_t	context,
		globus_gsi_authz_cb_t	callback,
		void *	callback_arg
	)

Initialize an authorization handle.

Initialize an authorization handle by calling the GLOBUS_GSI_AUTHZ_HANDLE_INIT function named in the authorization configuration file. The parameters to this function are passed to the authorization callout. Once the initialization is complete, the callback function is called, with the result and the callback_arg passed to it.

Parameters

handle	Pointer to the handle that is to be initialized
service_name	Service to authorize access to
context	Security context used to contact the service
callback	Callback function to call when authz handle init completes
callback_arg	Argument to callback function

Return values

The	globus_gsi_authz_handle_init() function returns GLOBUS_SUCCESS if successful, or a Globus error object on failure
