#include <sasl/sasl.h>
int sasl_user_exists( sasl_conn_t *conn,


                      const char *service,


                      const char *user_realm,


                      const char *user)

  • conn – the SASL context for this connection
  • service – Service name or NULL (for service name of connection context)
  • user_realm – Realm to check in or NULL (for default realm)
  • user – User name to check for existence.
