Reproduction steps:

1. Deploy a clean Liferay tomcat bundle
2. Log in with an admin user
3. Create 2 public pages under the default site
   • Login (widget page) with url "/login" and place "Sign In" portlet on that page
   • Protected (widget page) with url "/protected" and remove guest view permission from that page
4. Log out and make sure that page 'Protected' is not visible in navigation
5. Log in and make sure default admin works fine
6. Shutdown server and configure JAAS
   • Place attached "jaas.config" file in "tomcat/conf/" folder
   • Configure the java login configuration by adding the following property to
     CATALINA_OPTS in "setenv. bat" (or .sh): -Djava.security.auth.login.config=%CATALINA_HOME%\conf\jaas.config
   • Configure portal realm in tomcat by adding the following section to Catalina engine in "tomcat/conf/server.xml"
     <Realm className="org.apache.catalina.realm.JAASRealm"
     appName="PortalRealm"
     userClassNames="com.liferay.portal.kernel.security.jaas.PortalPrincipal"
     roleClassNames="com.liferay.portal.kernel.security.jaas.PortalRole"
     useContextClassLoader="false"
     debug="99"
     />
   • Activate JAAS in DXP by adding the following lines to portal-ext.properties:
     company.security.auth.type=screenName
     portal.jaas.enable=true
     portal.jaas.auth.type=screenName
   • disable session persistence in tomcat by uncommenting the following line in "tomcat/conf/context.xml": <Manager pathname="" />
7. Start the server and go to page /login, make sure that login works and Protected page shows up in navigation
8. Log out and try to access /protected
9. You will be redirected to login page
10. Enter your admin credentials

Expected result: You get logged in
Actual result: The screen name cannot be blank

No additional log entries or errors or stacktraces show up.
