sasl_client_init – SASL client authentication initialization Synopsis #include <sasl/sasl.h> int sasl_client_init(const sasl_callback_t *callbacks); Description sasl_client_init() initializes SASL. It must be called before any calls to sasl_client_start. This call initializes all SASL client drivers (e.g. authentication mechanisms). These are usually found in the /usr/lib/sasl2 directory but the directory may be overridden with the SASL_PATH environment variable….

This function is subject to the requirements that all user canonicalization functions are: It…

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…

sasl_auxprop_request – Request Auxiliary Properties from SASL Synopsis #include <sasl/sasl.h> int sasl_auxprop_request(sasl_conn_t *conn, const char ** propnames) Description sasl_auxprop_request will request that the SASL library obtain properties from any auxiliary property plugins that might be installed (such as the user’s home directory from an LDAP server for example). Such lookup occurs just after username canonicalization…

sasl_auxprop_getctx – Acquire an auxiliary property context Synopsis #include <sasl/sasl.h> int sasl_auxprop_getctx(sasl_conn_t *conn) Description sasl_auxprop_getctx will return an auxiliary property context for the given sasl_conn_t on which the functions described in sasl_auxprop(3) can operate. conn the sasl_conn_t for which the request is being made. Return Value Returns a pointer the the context on success. Returns…

sasl_auxprop – How to work with SASL auxiliary properties Synopsis #include <sasl/prop.h> struct propctx *prop_new(unsigned estimate) int prop_dup(struct propctx *src_ctx, struct propctx *dst_ctx) int prop_request(struct propctx *ctx, const char **names) const struct propval *prop_get(struct propctx *ctx) int prop_getnames(struct propctx *ctx, const char **names, struct porpval *vals) void prop_clear(struct propctx *ctx, int requests) void prop_erase(struct propctx…

sasl_authorize_t – The SASL authorization callback Synopsis #include <sasl/sasl.h> int sasl_authorize_t(void *context, const char *requested_user, unsigned alen, const char *auth_identity, unsigned alen, const char *def_realm, unsigned urlen, struct propctx *propctx) Description sasl_authorize_t is used to check whether the authorized user auth_identity may act as the user requested_user. For example the user root may wish to…
