Nuxeo: after activating the Anonymous User can't log in

Question

My goal is to add the anonymous authentication to Nuxeo web ui.

I followed the steps on https://doc.nuxeo.com/nxdoc/how-to-define-public-pages-viewable-by-anonymous-users/.

1. Created anonymous-auth-config.xml with the following content:

<component name="org.nuxeo.ecm.platform.login.anonymous.config">
  <!-- Add an Anonymous user -->
  <extension target="org.nuxeo.ecm.platform.usermanager.UserService"
    point="userManager">
    <userManager>
      <users>
        <anonymousUser id="Guest">
          <property name="firstName">Guest</property>
          <property name="lastName">User</property>
        </anonymousUser>
      </users>
    </userManager>
  </extension>
</component>

First I copied the file into the C:\Nuxeo\nxserver\config then try folder C:\Nuxeo\templates\common\config.

2. Modified nuxeo.conf and set nuxeo.user.anonymous.enable=true.
3. Restart the application server.

Now I can only enter the web ui as Anonymous user, but can't log in as Administrator or any other valid user.

There is forceAnonymousLogin=true query string in the url now by default.

I'm not sure should I change and how the authenticationChain as stated in another link: https://doc.nuxeo.com/nxdoc/using-anonymous-authentication/

Thanks for your help in advance!
