Is there a Dummies guide to configuring Tomcat to use basic Authentication tokens when using external parties want to consume a Uniface webservice?

I hope it can help you.
A quick googling reveals two other well written sources, because the one already linked from Jonathan Degoumois is always "out of bandwidth":

Hope it helps...
There is some documentation in the uniface library about enabling webserver authentication
https://u.uniface.info/docs/1000/uniface/webApps/applicationIssues/authentication/Other_Authentication_Methods.htm?tocpath=Developing%20Web%20Applications%7COther%20Programming%20Considerations%7CAuthentication%20for%20Uniface%20Web%20Applications%7C_____2
and
https://u.uniface.info/docs/1000/uniface/webApps/applicationIssues/authentication/Uniface_Authentication_Method.htm?tocpath=Developing%20Web%20Applications%7COther%20Programming%20Considerations%7CAuthentication%20for%20Uniface%20Web%20Applications%7C_____1
Are these of any help?
Kind regards,
