Whilst Zimbra provides a full suite of collaboration applications, integration with third party collaboration systems is possible via Zimbra's Zimlet technology.

Zimlets are a mechanism for integrating the Zimbra Collaboration Suite with third party information systems and content as well as creating "mash-up" user interfaces within the Zimbra suite itself. Zimlets save end users time by condensing common tasks, which typically force them to open multiple applications, into simple contextual ones within ZCS web client. Zimlets essentially encapsulate three things:

  • Richly-interactive user interface in the browser: With technologies like AJAX, web user interfaces can be every bit as rich as that of traditional client/server applications, but at the same time still have the look, feel, behaviour, and zero client administration of the World-Wide Web;
  • XML-based web services: Service-Oriented Architecture (SOA) based on XML/web service end-points allows Internet data and services (maps, stock quotes, weather, flight status, etc.) and intranet data and services (enterprise applications such as CRM, ERP, etc.) to be securely accessed from other applications and systems;
  • Mash-ups: mash-ups are the aggregation and customization of multiple web user interfaces and web services to eliminate context switching between existing systems or deliver complete new experiences.

Mobile Sync.

Mobile devices can automatically synchronize:

  • messages;
  • agendas;
  • contacts.

Synchronizations are proactive and performed in real time mode called "push" for terminals that support it. In case of loss the terminals can be locked from the synchronization, or even emptied remotely depending on the model.

The technical prerequisites are:

  • Subscription standard DATA (20 MB is sufficient for a month of traffic).

Connection with an external LDAP or Active Directory

Zimbra may by default connect to an Active Directory server to be provisioned with accounts. However, it does not automatically update. We install hence specific scripts for the automatic provisioning from Active Directory or OpenLDAP instead, specify the automatic refresh intervals, and specify settings related to your operation.

Details of the synchronization directory with Zimbra.

We intend to use the IDs from your directory to synchronize:

  • users;
  • groups;
  • profiles;
  • rights.

This will allow a constant consistency between the repository and Zimbra. For example:

  • group "management" has a higher mail quota;
  • people in the group "mobile" can synchronize their mobile devices.
  • Authentication
  • In terms of authentication, Zimbra authenticates the accounts directly from Active Directory (or another directory service), if configured. Otherwise, Zimbra integrated OpenLDAP service is used for authentication

Data migration

Zimbra offers a large number of migration wizards. Here are the following steps for the Zimbra migration :

  • Zimbra configuration : Configuration and testing for sample accounts;
  • Migration configuration : Splitdomain or proxy mail setup, implementation of the migration tools;
  • Provisioning : LDAP or AD sync, users provisioning, provisioning validation, roles configuration;
  • Validation : Supplier validation, customer validation before switching to the new solution;
  • Transition : DNS changes, user access changes;
  • Migration : user data migration (mails, calendars, repository, etc.), system data migration (distribution lists, aliases);
  • Validation : of the data migration and mail routing;
  • Automatisms : automatic LDAP or AD sync activation, backup scripts activation;
  • Validation : Validation of the client's migration.

No interruption of services during the migration

The SplitDomain manages emails routing toward the legacy mail server or Zimbra depending on the location of the user's account.

An email arrives and is taken care of by the Splitdomain mechanism on the Zimbra server;

  • If the user exists on the Zimbra server, the email is delivered;
  • If the user does not exist on the Zimbra server, the email is routed toward the legacy mail server;
  • If the account is in the migration process, Zimbra Mail Queue stocks messages until the end of the migration.
