Mac file sharing

Hi I have a situation where I have a number of Mac OS 10.13.4 machines that I need to share a folder with without the need for the users to enter any credentials.

The folder share is set up so that the ‘everyone’ and ‘staff’ groups have full access and the guest account on the Mac hosting the share is enabled for file sharing only but whenever the other machines try to access the share it prompts for credentials when I do not want it to.

Is there any way around this?
