It's your SELECT that's causing the ORA-1422. If you're using 8i or 9i, you can avoid the SELECT and use the SYS_CONTEXT function like this:

CREATE OR REPLACE TRIGGER CONTROL_DDL
   BEFORE DDL ON DATABASE
BEGIN
   INSERT INTO CONTROL_OBJETOS

	(USUARIO,	BASE_DATOS,
	HORA,		OPERACION, 
	ESQUEMA,	TIPO_OBJETO,
	OBJETO,	MAQUINA,
	USUARIO_OS)
   VALUES
	(ORA_LOGIN_USER,	ORA_DATABASE_NAME,
	SYSDATE,		ORA_SYSEVENT,
	ORA_DICT_OBJ_OWNER,	ORA_DICT_OBJ_TYPE,
	ORA_DICT_OBJ_NAME,	SYS_CONTEXT('USERENV','TERMINAL'),
	SYS_CONTEXT('USERENV','OS_USER'));

END; (Note: I didn't test this code!!!!)

HTH! GL! :)
