sasl_authorize_t

- the SASL authorization callback

Synopsis

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

int sasl_authorize_t(sasl_conn_t *conn, const char *requested_user,
     unsigned alen, const char* auth_identity, unsigned rlen,
     const char *def_realm, unsigned urlen, struct propctx *propctx);

Description

sasl_authorize_t() is a typedef function prototype that defines the interface associated with the SASL_CB_PROXY_POLICY callback.

Use the sasl_authorize_t() interface to check whether the authorized user auth_identity can act as the user requested_user. For example, the user root may want to authenticate with root's credentials but as the user tmartin, with all of tmartin's rights, not root's. A server application should be very careful when it determines which users may proxy as other users.

alen

default_realm

The default user realm as passed to sasl_server_new(3SASL).
