sasl_getprop - Get a SASL property


#include <sasl/sasl.h>

int sasl_getprop(sasl_conn_t *conn,
                int propnum,
                const void ** pvalue);


int sasl_getprop(sasl_conn_t *conn,
int propnum,
const void ** pvalue);

sasl_getprop gets the value of a SASL property. For example after successful authentication a server may wish to know the authorization name. Or a client application may wish to know the strength of the negotiated security layer.

  • conn – is the SASL connection context
  • propnum – is the identifier for the property requested
  • pvalue

    is filled on success. List of properties:

    • SASL_USERNAME ‐ pointer to NUL terminated user name
    • SASL_SSF ‐ security layer security strength factor,
      if 0, call to sasl_encode(3), sasl_decode(3) unnecessary
    • SASL_MAXOUTBUF ‐ security layer max output buf unsigned
    • SASL_DEFUSERREALM ‐ server authentication realm used
    • SASL_GETOPTCTX ‐ context for getopt callback
    • SASL_IPLOCALPORT ‐ local address string
    • SASL_IPREMOTEPORT ‐ remote address string
    • SASL_SERVICE ‐ service passed to sasl_*_new
    • SASL_SERVERFQDN ‐ serverFQDN passed to sasl_*_new
    • SASL_AUTHSOURCE ‐ name of auth source last used, useful for failed
      authentication tracking
    • SASL_MECHNAME ‐ active mechanism name, if any
    • SASL_PLUGERR ‐ similar to sasl_errdetail

Return Value

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

Other return codes indicate errors and should be handled.
