Disabling authentication for web service call on webMethods 7.1

Can anyone help me how to configure anonymous web service call on webmethods 7.1 ?
Cause we’ve just migrate from 6.5 to 7.1, on 6.5 the created service can be invoke by web service client using anonymous, but the problem is come from the new built service on 7.1 that can not be call using anonymous. Since the client only can invoke using anonymous call (6.5 are ok to do this) but can not accomplish this 7.1 requirement of authentic call.

Thanks

It’s done.
It seems there’s an ACL bug on webMethods 7.1. Because if the Anonymous ACL on folder are inherited to the child (servcie), it can’t run. but if you force it to anonymous it can run.
