You need to upgrade. Current 6.0.x version if 6.0.51. Current stable
version is (IMO) 8.0.42.

Does the application understand anything about LDAP authentication, or
are you asking how Tomcat can be configured to request the username
and password for the user?
The LDAP backend is just the way that the authentication and
authorization is performed. Credential-gathering is typically
performed using one of the following:
1. HTTP Basic "authentication"
2. HTTP Digest "authentication"
3. FORM login (username/password in a web form)
4. SSL/TLS client certificate
Which of the above did you have in mind? If you are just slapping
authentication on top of an existing application that doesn't have its
own login process, then I would recommend using HTTP Basic
"authentication" (I use parens around "authentication" because it's
not authenticating at all... it's just providing credentials that the
server can use for authentication). When using HTTP Basic
"authentication" it is absolutely required that you use TLS to encrypt
the channel.

You need to resolve those issues. Any software product that has
security components cannot be trusted after it reaches end-of-life.
Any EOL'd product should be considered known-vulnerable as soon as
that EOL date arrives.

Redirects or proxies? Adding a redirect will only work for users who
are sitting at your actual computer (localhost).

Is there a reason not to require a username and password for all
users, regardless of the hostname they use to access the application?
