NAME

       sasl_getrealm_t - Realm Acquisition Callback

SYNOPSIS

       #include <sasl/sasl.h>

       int sasl_getrealm_t(void *context, int id,
		       const char **availrealms,
			   const char **result)

DESCRIPTION

       sasl_getrealm_t is used when there is an interaction with SASL_CB_GETREALM as the type.

       If  a mechanism would use this callback, but it is not present, then the first realm listed is automatically selected.  (Note that a mecha-
       nism may still force the existence of a getrealm callback by SASL_CB_GETREALM to its required_prompts list).

       context context from the callback record

       id callback ID (SASL_CB_GETREALM)

       availrealms A string list of the available realms.  NULL terminated, may be empty.

       result The chosen realm. (a NUL terminated string)

RETURN VALUE

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

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.
