Tomcat Experts:

 

                The Tomcat server works fine in my local computer with  application “TOPS“ in Eclipse.  I deployed the TOPS application to our DEV web server eagnmnmed1f45 under webapps. 

 

                After I started the Tomcat  server (9.0.13) in DEV server and entered the TOPS home page URL  http://eagnmnmed1f45:9080/TOPS-WEB/Welcome.do (It is http://localhost:8080/TOPS-WEB/Welcome.do  in my local computer)   in the browser,   I got the following error:

          Notice that I entered non secure port 9080 and then was re-direct to secure 9443. 

 

         If I only entered  “http://eagnmnmed1f45:9080/TOPS-WEB/”,  the login screen showed up as below:

 

 

 

But after I entered   topsadmin/@88Topstopstops as id/pd and clicked Login button,    I got the following error:

 

 

I know the  topsadmin/@88Topstopstops is the correct id/pd.

 

Any idea what happens here?     Any input is appreciated.   Following is the contents of server.xml and LDAP_realm.xml
