And if you have ideas about improving the CommentAuthenticator, nows a
good time to speak up. We're considering some changes to the comment
servlet to add CommentValidators. See:

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);

}
