Hi, I am using Tomacat Autehntication Login page and LDAP Settings as Log in page to my Struts application. When I retrieve the user profile using request.getRemoteUser() , Iam able to fetch the user name logged in on my machine(where I run my server). When I run the same app on diff mahchine the user is name is null. Any idea why its null ??, thanks in adavance.
