A few question on this segment of HTML. First, is it possible to set
commentAuthor Cookie from commentAuthenticator's getHTML? If yes, how?
There is no response object from that method.
Second, where is commentForm? The form name seems to be "form"? Is this
a bug?

Yes, you'll need to do a little Java coding, but it is possible to
implement your own comment authenticator. Here are the steps:
1) Implement the CommentAuthenticator interface below and in it,
check for LDAP login.
2) Put your implementation into the Roller classpath (e.g. in a jar in
WEB-INF/lib)
3) In your roller-custom.properties file override the property
'comment.authenticator.classname' and set it to your classname.
And here's the interface CommentAuthenticator.java:
package org.apache.roller.ui.rendering.util;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.roller.pojos.CommentData;
import org.apache.velocity.context.Context;
/**
* Interface for comment authentication plugin.
*/
public interface CommentAuthenticator {
/**
* Plugin should write out HTML for the form fields and other UI
elements
* needed to display the comment authentication widget.
* @param request comment form request object
*/
public String getHtml(HttpServletRequest request);
/**
* Plugin should return true only if comment posting passes the
* authentication test.
* @param request comment posting request object
* @return true if authentication passed, false otherwise
*/
public boolean authenticate(HttpServletRequest request);
}
