How to get a user's last login date?

sdeyres — Tue, 04 Oct 2016 10:08:07 GMT

Hi,I'd like to get a user's last login date. I searched the forum, and based on this thread (Re: get last login? ), it appears that I have two solutions to do this: enable audit (which seems a bit overkill to just get the last login date), or create a new aspect and extend the LoginBean to update t

Maybe you can start from this custom authenticator alfresco-sdk-samples/all-in-one/custom-authentication-repo at alfresco-51 · Alfresco/alfresco-sdk-samples · GitHub

Hi,

From what I understand, this implementation would require me to handle the authentication itself (i.e. connect to the LDAP server and check user credentials, etc.); I would simply like to let Alfresco handle this on its own, just like it does today, and once the authentication is performed, update the user information.

Isn't there some kind of event to which I could subscribe so I can update the user once he's logged in? Or maybe I'm missing something in your answer...

Anyway, thanks for your answer.

Sylvain.

My suggestion was to build a new "LoggerAuthenticationComponentImpl.java" as is suggested in the sample. You can log any information at "authenticateImpl" method and delegate authentication stuff in "super".

Alternatively, you can always use the audit component / service to record logins and use that to determine the last login date. This requires no implementation for recording the date, only configuration of the audit component. The default audit access config already contains everything you would need as far as I know.

No,you don't need to implement all code to handle the authentication ,you can inherit from existing class that alfresco provided.

The easiest way to do it like this:

For example if you use the default authentication chain,you can just customize your own class and inherit org.alfresco.repo.security.authentication.AuthenticationComponentImpl,the only methd you have to override is following

@Override

protected void authenticateImpl(final String userNameIn, final char[] password) throws AuthenticationException{

super.authenticateImpl(userNameIn, password);

//add your code here

}

create a spring configuration name file like ***-context.xml with content like following and place it into alfresco/extension/subsystems//Authentication/alfrescoNtlm

<?xml version='1.0' encoding='UTF-8'?>

<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>

<beans>

<bean id="authenticationComponent" class="******.YourAuthenticationComponentImpl"

parent="authenticationComponentBase">

</property>

</property>

</property>

<value>${alfresco.authentication.allowGuestLogin}</value>

</property>

</property>

</property>

</property>

<set>

<value>${alfresco_user_store.adminusername}</value>

<value>administrator</value>

</set>

</property>

<set>

<value>${alfresco_user_store.guestusername}</value>

</set>

</property>

</bean>

</beans>

And same as Axel Faust ,I also recommend using audit component

kayne zhang Obviously I was suggesting that, giving the code as sample and including that "super" in my response for the "authenticateImpl" method. However, thanks for clarifying, if it was not clear for you, it wasn't clear for others. Thanks

Thanks for your inputs. So, if I get this right...

My authentication chain looks like this:

authentication.chain=external1:external,alfrescoNtlm1:alfrescoNtlm,all:ldap-ad

So basically, I should extend org.alfresco.repo.security.authentication.ldap.LDAPAuthenticationComponentImpl, and overload its authenticateImpl method in the following way:

  @Override 
  protected void authenticateImpl(String userName, char[] password) {
     super.authenticateImpl(userName, password);

     final NodeService nodes = getNodeService();
     final PersonService people = getPersonService();
     final Date now = new Date();

     try {
       NodeRef user = people.getPerson(userName);
       if (nodes.exists(user)) {
         if (nodes.hasAspect(user, LastConnectionAspect.ASPECT_LAST_CONNECTION)) {
           nodes.setProperty(user, LastConnectionAspect.PROP_LAST_CONNECTION, now);
         } else {
           Map<QName, Serializable> properties = new HashMap<>();
           properties.put(LastConnectionAspect.PROP_LAST_CONNECTION, now);
           nodes.addAspect(user, LastConnectionAspect.ASPECT_LAST_CONNECTION, properties);
         }
       }
     } catch (Exception exception) {
       LOGGER.error("Could not set last connection date: " + exception);
     }
   }

And then, I should create the bean configuration file in alfresco/extensions/subsystems/Authentication/LDAP.

Am I right?

Thanks again for your time,

Sylvain.

In my opinion, you should extend the abstract class like it's done at alfresco-sdk-samples/CustomAuthenticationComponentImpl.java at alfresco-51 · Alfresco/alfresco-sdk-samples · GitHub

You can include the code suggested by kayne zhang there:

@Override

protected void authenticateImpl(final String userNameIn, final char[] password) throws AuthenticationException{

super.authenticateImpl(userNameIn, password);

//add your code here

}

Then you can include your context (alfresco-sdk-samples/customauthenticator-authentication-context.xml at alfresco-51 · Alfresco/alfresco-sdk-samples · Git… ) and your properties (alfresco-sdk-samples/customauthenticator-authentication.properties at alfresco-51 · Alfresco/alfresco-sdk-samples · GitH… ) inside your AMP or in extended alfresco configuration folders.

Finally, you can include your custom authenticator in your alfresco global configuration file alfresco-sdk-samples/alfresco-global.properties at alfresco-51 · Alfresco/alfresco-sdk-samples · GitHub

I don't get it,

How would the super.authenticateImpl() call do anything since the parent class is abstract?

Thanks for your inputs,

Sylvain.

You're right.

You can try overwriting following Spring bean:

by using your customised class:

and then override that authenticateImpl() method extending from org.alfresco.repo.security.authentication.AuthenticationComponentImpl

I've wrote a quick sample to include a custom authenticator for login as first component in authentication chain. Please, check GitHub - angelborroy/alfresco-logger-authenticator: Custom authenticator for Alfresco It's not perfect, but can be used as reference.

Probably it's a better idea to implement Axel Faust approach, but I have no experience on that kind of customisation.

Almost like this，But Audit component is recommended.

Audit component provides feature to track user activities include user login .And Audit data is accessible via the AuditService ,audit web scripts,So you don't need to implement your own.It is less intrusive than cusomized authentication.

Alfresco's default audit configuration already persists login success, login failure and logout events data.But it also persist more other data for general use.

If you only need login data,you can customize your configuration using alfresco-audit-example-login.xml.sample as an example.

About how to customize audit ,you can refer to http://docs.alfresco.com/5.1/references/dev-extension-points-audit.html
