In this Repository you will find a simple Zimlet to connect Zimbra Collaboration with Rocket Chat, and make an amazing integration with both inside the Zimbra Web Client, it will look like:

On this github we will not cover the installation of Rocket Chat, as it's perfectly explained here:

• https://rocket.chat/docs/installation/minimum-requirements
• https://www.digitalocean.com/community/tutorials/how-to-install-configure-and-deploy-rocket-chat-on-ubuntu-14-04
• https://www.howtoforge.com/tutorial/how-to-install-rocket-chat-with-nginx-on-ubuntu-16-04/

Rocket Chat it's also designed to be deployed on Docker or Ubuntu Snap, which is really great:

• https://rocket.chat/docs/installation/docker-containers/
• https://rocket.chat/docs/installation/manual-installation/ubuntu/snaps/

This Zimlet can automatically log your users on to Rocket chat and even automatically create new users on Rocket chat. That way you only need to maintain the user accounts on Zimbra (full integration). Or you can maintain your Rocket accounts via LDAP or manually, but still log them on automatically (logon-only integration). Or you can just deploy only the Zimlet and let the user decide on the authentication (basic integration).

1. Full integration For this you need to set-up the Java server extension copy it from https://github.com/Zimbra-Community/zimbra-rocket/releases to /opt/zimbra/lib/ext/rocket/extension.jar then create a text file /opt/zimbra/lib/ext/rocket/config.properties with the contents:

    adminuser=adminUsername
    adminpassword=adminPassword
    rocketurl=https://rocket.example.org
    loginurl=https://mail.example.org
   

This adminuser and password you should have created when you first installed Rocket. The loginurl is the place where we point users to that have not yet authenticated. This can be your SSO login page or the Zimbra login page. Don't forget zmmailboxdctl restart.

You must also configure Rocket chat like so: Be careful, as you can easily lock yourself out if something does not work. If you want more details check: https://github.com/Zimbra-Community/zimbra-rocket/wiki/Debugging

Also enable the full iframe integration like so:

You must also configure and deploy the Zimlet: Get a com_zimbra_rocket.zip (from Github releases) and as Zimbra user:

  zmzimletctl deploy com_zimbra_rocket.zip

To configure the rocketurl in the Zimlet

  zmzimletctl getConfigTemplate /opt/zimbra/zimlets/com_zimbra_rocket > /tmp/config_template.xml.tmp

Edit the /tmp/config_template.xml.tmp file according to your needs. Import the new configuration file by the running following command:

  zmzimletctl configure /tmp/config_template.xml.tmp

2. Logon-only integration Follow the same steps as under Full integration except when configuring the Zimlet set createRocketAccount to false. You may also want to configure Rocket to use Zimbra LDAP. See steps below.

3. Basic integration You must configure and deploy the Zimlet: Get a com_zimbra_rocket.zip (from Github releases) and as Zimbra user:

   zmzimletctl deploy com_zimbra_rocket.zip

Configure the rocketurl in the Zimlet and set createRocketAccount to false

  zmzimletctl getConfigTemplate /opt/zimbra/zimlets/com_zimbra_rocket > /tmp/config_template.xml.tmp

Edit the /tmp/config_template.xml.tmp file according to your needs. Import the new configuration file by the running following command:

  zmzimletctl configure /tmp/config_template.xml.tmp

Their appears to be an issue in meteor (the platform on which Rocket is build) that results in authentication tokens not being purged. This is a performance and security issue, as one user record can have thousands of valid tokens slowing down the db. To fix this configure a clean-up cron.

Create a file /usr/local/sbin/rocket-token-purge with contents:

  #!/bin/bash
  cd /snap/rocketchat-server/*/
  ./bin/mongo parties --eval 'db.users.update({}, { $set: { "services.resume.loginTokens": []}},{multi: true})'

run chmod +rx /usr/local/sbin/rocket-token-purge and put it in cron crontab -e like so:

  2 3 1 * * /usr/local/sbin/rocket-token-purge

This will log people out of the Rocket.Chat app on their phone, so they need to re-enter their credentials.

Configure Rocket Chat with the Zimbra LDAP is really easy, and you must follow the next steps:

Go to Administration and then LDAP, and enable the LDAP option, mark the option as shown, change the LDAP hostname with your Zimbra one (the Rocket and the Zimbra must have Network visibility)

On the Domain Base add the next, change it with your domain: ou=people,dc=zimbra,dc=io On the Domain Search User select the next: uid=zimbra,cn=admins,cn=zimbra On the Domain Search Password add your LDAP Password, you can retrieve on the Zimbra server with zmlocalconfig -s zimbra_ldap_password

On the next fields, please fill them as shown:

On the latest fields, fill them as shown and finally click on test, and Sync users, and Save

Zimbra Rocket doesn't end into an amazing look-a-like Slack experience, and you can even integrate your Zimbra Talk to make video calls between users, one-to-one and one-to-many, follow the next steps to enable it:

Go to Administration > Videoconference and add your Zimbra Talk FQDN, and the Zimbra Talk Chrome ID for the Share Screen Feature:

Then the users will be able to call each other, or to groups by using the camera icon:
