Our preflight installer script needs to add an authorization right. This worked on OS X 10.4-10.8 but suddenly stopped working on OS X 10.9 DP1. AuthorizationRightSet() fails with -60005 (errAuthorizationDenied), and the following error message is logged by authd: "Jul 20 07:20:15 Testers-Mac.local com.apple.authd[66]: server[584]: AuthorizationRightSet Denied process identifier not found, missing code signature." Our installer runs as superuser. Executing the below code from a command line program by root fails in the same manner. Here's the source code: int SetAuthRight() {    OSStatus status;    AuthorizationRef auth;    status=AuthorizationCreate(NULL, kAuthorizationEmptyEnvironment, kAuthorizationFlagDefaults, &auth);    if(status!=noErr){       syslog(LOG_ERR, "AuthorizationCreate failed: %d.", (int)status);       return -1;    }    status=AuthorizationRightSet(auth, "mycompany.myapp.auth", CFSTR(kAuthorizationRuleAuthenticateAsAdmin), CFSTR("my_display_message"), NULL, NULL);    AuthorizationFree(auth, kAuthorizationFlagDefaults);    if(status!=noErr){       syslog(LOG_ERR, "AuthorizationRightSet failed: %d.", (int)status);       return -1;    }    return 0; } Thanks in advance.
