Lines 65 to 68 in b63c03a

	// Do exactly the same thing for both auth and account invocations.
	pam_sm_authenticate(pamh, flags, argc, argv);
	return PAM_SUCCESS;

If this module is implemented with an account module instead of an auth module, it always returns success, regardless of what OPA says it should.

Instead, it should return the value on line 66, not discard it.
