When playing with Authentication service filter chains, it was found that the filter chain test on the Authentication page didn't always choose the correct filter chain.
To replicate, create a filter chain called wms and use the ant pattern /wms/** on a filter chain with everything else left as default. Click close and then save and then navigating back to the authentication page. Then click on the find chain button with the below url displays default for the filter chain test result.
Selecting the chain filter anonymous for the default filter chain and basic for the wms filter chain above and then entering the url below in a separate browser causes the browser to show a basic authentication login dialog.
