NAME
sasl_callbacks - How to work with SASL callbacks
SYNOPSIS
#include <sasl/sasl.h>
DESCRIPTION
sasl_callbacks are used when the application needs some information from the application. Common reasons are getting for getting usernames
and passwords. A client MUST specify what callbacks they support in the sasl_client/server_init() or sasl_client/server_new() calls. If an
authentication mechanism needs a callback that the application does not state it supports it cannot be used.
If a callback has an id parameter that should be checked to make sure you are giving the appropriate value.
If an application is using the client side of the library functions to handle the callbacks are not necessary. Instead the application may
deal with callbacks via SASL_INTERACT's. See sasl_client_start/step() for more information.
The list of callbacks follows:
Common Callbacks
sasl_getopt_t
Get an option value
sasl_log_t
Log message handler
sasl_getpath_t
Get path to search for mechanisms
sasl_verifyfile_t
Verify files for use by SASL
sasl_canon_user_t
Username canonicalization function.
Client-only Callbacks
sasl_getsimple_t
Get user/language list
sasl_getsecret_t
Get authentication secret
sasl_chalprompt_t
Display challenge and prompt for response
sasl_getrealm_t
Get the realm for authentication
Server-only Callbacks
sasl_authorize_t
Authorize policy callback
sasl_server_userdb_checkpass_t
verify plaintext password
sasl_server_userdb_setpass_t
set plaintext password
RETURN VALUE
SASL callback functions should return SASL return codes. See sasl.h for a complete list. SASL_OK typically indicates success.

I want to create a new user and grant him ONLY transfer files access to a specific directory where he can only upload and read the files. He should be restricted to this activity only.
