Using NXRM 3.20.1
1. Open the default UI Page by entering the NXRM hostname and port. You will not be prompted to authenticate if the Anonymous user is enabled and has the default privileges.
2. Sign-in as a NXRM administrator by clicking sign-in.
3. Open a page under the Administration menu
4. Click Sign-out.
Your session will end, but the user will immediately be presented with an authentication dialog because the URL in the web browser still points at a restricted Administration page.
This is a regression introduced in 3.18.0. Testing with 3.17.0-01 and earlier, signing out redirects back to the default page http://localhost:8081/#browse/welcome and does not prompt to authenticate.
Your session ends on sign-out and the UI redirects to Welcome page as it did in previous versions. The user will not be prompted ( by default )to authenticate because Anonymous user has access to that page.
