#include <sasl/sasl.h> 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 object. propnum is the identifier for the property requested and pvalue is filled in on success. List of properties follows:
SASL_USERNAME - pointer to NUL terminated user name SASL_SSF - security layer security strength factor, if 0, call to sasl_encode, sasl_decode 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
