Kopano Groupware Core 8.7 Beta


  • Kopano

    Kopano Groupware Core 8.7 is the first release to include a range of new components for the Kopano platform. These new components include support for OpenID Connect and initial support for our new RestAPI. Apart from this version 8.7 also brings performance and security improvements.

    Kopano Groupware Core provides the Groupware functionality of the Kopano stack and in most cases sits at the heart of every Kopano environment. It is therefore a key figure in our promise to deliver stability and extensibility of Kopano’s proven communication platform. Kopano Archiver consists of additional archiving components, allowing Kopano Groupware servers to run on dedicated, and sometimes slower, storage servers for archived messages, while keeping the items available to the user.

    New components in Kopano Groupware Core 8.7

    Kopano 8.7 introduces two new components, which will play an important role in future client development and the integration of Kopano with external applications and platforms. The first new component that I want to introduce is Kopano Konnect. Konnect is an OpenID provider (OP) that directly integrates a web login with a consent form. It brings support for both OpenID Connect (OIDC) and Open Authentication (OAuth 2.0). Through this tool administrators can easily allow their users to login at third party applications, such as Owncloud and Nextcloud with the “Social Login” plugin, Wordpress, OpenProject and many more. In addition to the easier integration with third-party applications, Kopano Konnect will also provide the authentication for the Kopano RestAPI and clients consuming it.

    Want to learn more about Konnect? In the past we already gave a short introduction into Kopano Konnect. There are two main changes since the release blog post: you can now install Konnect through distribution packages and you no longer need to rely on Docker or binary downloads. Are you running Kopano on Univention Corporate Server and want to give Konnect a try? Kopano Konnect is available as Open ID provider with added Univention branding and integration on UCS.

    Another new component is our new RestAPI “Kopano API” (or KAPI for short). KAPI is modelled after the Microsoft Graph RestAPI and will make it easier than ever before to integrate your Kopano data with external applications and clients. App developers should make sure to check our Compat documentation for further information on Graph and where we differ in our implementation. The first new client that will make use of KAPI is the Kopano Meet. We will have another blog on this subject in the beginning of 2019.

    The Kopano RestAPI is only available for Debian 9, Ubuntu 16.04 and Ubuntu 18.04 at the moment. The API backend is made in Python3 and other distributions (RHEL, SLES, Debian 8) either do not have all dependencies in their repositories or not a recent enough version of Python. Support for SLES and RHEL will be added later on. The usage of Kopano WebApp or Z-Push is not affected by this.

    Improved performance and security

    Where available services now prefer python3 instead of python2.

    Reporting of usage statistics

    Starting with Kopano Groupware Core 8.7 the server process contains a new stats gathering and reporting functionality that is sending basic usage statistics back to us at Kopano. The transmitted statistics include:

    • a unique machine ID
    • the name of the submitting service
    • the version of the submitting program
    • an internal Kopano server GUID
    • an OS identifier
    • an identifier for the Kernel and architecture used
    • the configured Kopano user plugin
    • the number of active users
    • the number of contacts created
    • the number of inactive users (split in users, equipment and rooms)

    Internally we are also enhancing these stats with a timestamp when the system sends a report for the first time and another timestamp tracking when the the system contacted us last.

    Below is an example of how we store such a report internally:

    +------------------------------------------------------------------+------------------------------------------------------------------+------------------------------------------------------------------+---------------------+---------------------+----------------+-----------------+-------------------+-----------------+-------------------+------------+------------------------------+--------------------------------------------+---------------+-----------------+-------+
    | uid                                                              | machine_id_sha256                                                | server_guid_sha256                                               | first_seen          | last_update         | usercnt_active | usercnt_contact | usercnt_equipment | usercnt_na_user | usercnt_nonactive | userplugin | osrelease                    | utsname                                    | program_name  | program_version | flags |

    We hope to learn a bit more about our user base from these reports.

    How to turn the survey reporting off?

    The following configuration options in server.cfg have an influence over the report sending:

    • surveyclient_url
    • surveyclient_interval
    • surveyclient_ssl_verify

    To disable sending of reports it is sufficient to include the line surveyclient_interval=0 in your server.cfg

    Important configuration changes

    Some configuration options have changed compared to Kopano 8.6 or an earlier version. Below you will find a list of deprecated options and their replacements.

    server.cfg

    The following options are deprecated:

    • server_ssl_enabled
    • server_ssl_port
    • server_tcp_enabled
    • server_tcp_port

    The above options have been replaced with (these options were already available in Kopano Groupware Core 8.6.x):

    • server_listen
    • server_listen_tls

    ical.cfg

    The following options are deprecated:

    • ical_enable
    • icals_enable
    • ical_port
    • icals_port

    The above options have been replaced with:

    • ical_listen
    • icals_listen

    gateway.cfg

    The following options are deprecated:

    • imap_enable
    • imaps_enable
    • imap_port
    • imaps_port
    • pop3_enable
    • pop3s_enable
    • pop3_port
    • pop3s_port

    The above options have been replaced with:

    • pop3_listen
    • pop3s_listen
    • imap_listen
    • imaps_listen

    Upcoming changes in Kopano 8.8

    For the Kopano 8.8 release we are already planning some more changes, which we have announced in the “Housekeeping” blogpost. These changes can be summarised as:

    • switching to PHP 7.x compatibility only
    • switching to Python 3 compatibility only

    These changes will result in changed set of supported distributions from the release of Kopano Core 8.8 and onwards. More details can be found in the blog post.

    But there are also some smaller under the hood changes, that will only matter for custom integrations.

    For backwards compatibility we still provided a python-zarafa module within python-kopano. We plan to remove the compatibility bridge for Kopano Groupware Core 8.8.
    Additionally this release will also be the last release that to ship php class files. These files were already redundant, since both Kopano WebApp and Z-Push were shipping their own versions for quite a while. With the removal of the php version of kopano-mr-accept and kopano-mr-process in 8.7, these files are now no longer needed and will therefore be removed in the 8.8 release.

  • Hi Felix,
    in your repositories for pre-final are the repodata folders missing. Maybe you should automate this step ;)
    Only Debian based repos seem correct.

    @mkoas said in Kopano Groupware Core 8.7 Beta:

    Maybe you should automate this step ;)

    what makes you think this is not already the case?



  • Just guessed because the repodata is missing ;)
    Of course i don’t know which steps you execute automatically
    Primarily i just wanted to point out the issue of missing repodata


  • Kopano

    @mkoas Thanks, we’re looking into the issue.


  • Kopano

    @mkoas The issue should be fixed



  • @marty looks good
    I just saw it wants to install some mesa and x11 libraries on my CentOS 7 vm
    Is this the desired behaviour? If so it would be interesting for which feature this libraries are used :)
    Thanks in advance


  • Kopano

    @mkoas Maybe @fbartels knows


  • Kopano

    these packages are dependencies of poppler-utils, which was requested to be added as a dependency for kopano-search.

    https://jira.kopano.io/browse/KC-1245



  • @fbartels thanks for this info :)


  • Kopano

    Hi everyone, we have just updated the pre-final repo with a newer build. this also finally resolves the signing issues for rpm based distros (tested against rhel 7).
