Can i compare the username field value with one string value(like Administrator) in login.jsp?

veera_

Hi,

Can i compare the username field value with one string value(like Administrator) in login.jsp? How can i compare the username value with one string in this code?

If its equal means pass the value for authentication

else i have to set username value with null.

Can anyone help me?

Here is the code for username field in login.jsp

<tr>
<td class="login_label">
<label for="username"> <fmt:message bundle="${messages}" key="label.login.username" />
</label>
</td>
<td>
<input class="login_input" type="text" name="user_name" id="username" size="22">
</td>
</tr>

Thanks Veera

I don't really understand your need. Why don't you use a local user management that stores only your administrator? Anyway I give my answer to your specific question 🙂

The better way is not to attach your logic to the login page, but on the authentication filter. For multiple raison but the main is that you can login to Nuxeo with other way than the login page. So must work on a central point: Authentication layer.

You need to have a little knowledge about development to do that. Here is the guide line:

• install Nuxeo IDE
• declare an authenticator that filters users except administrator
• add it to the authentication chain
• deploy your contribution into the server.

You just have to contribute a new Authenticator that fail for other username than Administrator, else do the default behavior. So my piece of advice will be to create a authenticator that extends the default one:

public class AdministratorFilterAuthenticator extends ApplicationFormAuthenticator {

@Override
public UserIdentificationInfo handleRetrieveIdentity(
        HttpServletRequest httpRequest, HttpServletResponse httpResponse) {
            String userName = httpRequest.getParameter(usernameKey);
            if ("Administrator".equals(username)) {
                return super.handleRetrieveIdentity(httpRequest, httpResponse);
            }
            return null;
}

Finally you will have to add your authenticator to the authentication chain and declare your authenticator

  <extension
      target="org.nuxeo.ecm.platform.ui.web.auth.service.PluggableAuthenticationService"
      point="authenticators">

    <authenticationPlugin name="ADMINSITRATOR_FILTER_AUTH" enabled="true"
        class="org.nuxeo.ecm.mobile.filter.ApplicationFormAuthenticator">
      <needStartingURLSaving>true</needStartingURLSaving>
    </authenticationPlugin>
  </extension>
  <extension
      target="org.nuxeo.ecm.platform.ui.web.auth.service.PluggableAuthenticationService"
      point="chain">
    <authenticationChain>
      <plugins>
        <plugin>ADMINSITRATOR_FILTER_AUTH</plugin>
        <plugin>WEBSERVICES_AUTH</plugin>
      </plugins>
    </authenticationChain>
  </extension>

Hope this will help you.
