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 plugins (e.g. SASL 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

       sasl_getconfpath_t
	       Get path to search for SASL configuration file (server side only). New in SASL 2.1.22.

RETURN VALUE

       SASL callback functions should return SASL return codes. See sasl.h for a complete list. SASL_OK typically indicates success.

NAME

       sasl_verifyfile_t - the SASL file verification callback function

SYNOPSIS

       cc [ flag ... ] file ... -lsasl	 [ library ... ]
       #include <sasl/sasl.h>

       typedef enum {
	      SASL_VRFY_PLUGIN,       /* a DLL/shared library plugin */
	      SASL_VRFY_CONF,	      /* a configuration file */
	      SASL_VRFY_PASSWD,       /* a password storage file */
	      SASL_VRFY_OTHER	      /* some other file type */
       } sasl_verify_tyep_t

       int sasl_verifyfile_t(void *context, const char *file, sasl_verifyfile_t type);

DESCRIPTION

       Use  the  sasl_verifyfile_t()  callback	function check whether a given file can be used by the SASL library. Applications use sasl_verify-
       file_t() to check the environment to ensure that plugins or configuration files cannot be written to.

PARAMETERS

       context	       The context from the callback record

       file	       The full path of the file to verify

       type	       The type of the file

RETURN VALUES

       Like other SASL callback functions, sasl_verifyfile_t() returns an integer that corresponds to a SASL error code. See <sasl.h> for  a  com-
       plete list of SASL error codes.

ERRORS

       SASL_OK	       The call to sasl_verifyfile_t() was successful.

       See sasl_errors(3SASL) for information on SASL error codes.
