Introduction

The Open-Xchange Advanced Server Edition (OXASE)/Open-Xchange Server Edition for Univention Corporate Server (OXSE4UCS) includes the groupware Open-Xchange and the integration packages for Univention Corporate Server (UCS).

Open-Xchange Advanced Server Edition (OXASE)/Open-Xchange Server Edition for Univention Corporate Server (OXSE4UCS) is tailored to professional users looking for a tried-and-tested solution for the management of their entire IT infrastructure including groupware or companies which already employ UCS and wish to expand their infrastructure with innovative groupware functions.

More detailed information on UCS can be found on the Univention GmbH website: http://www.univention.de/dokumentation.html.

Differences between OXASE and OXSE for UCS

OXASE can not be used as

  • Domain Controller
  • Print Server
  • Database, web or directory service server (unless not for the exclusive use with Open Xchange)
  • IP management system
  • Software distribution system
  • Network or service monitoring system
  • Management tool for Windows or Linux based systems

Except for

  • the provisioning, use and management of file services („shares“) with the Samba software
  • the temporary, three-months limited, non-productive use of UCS for evaluation purposes

Installation

As OXASE/OXSE4UCS is an expansion pack for the Univention Corporate Server, one or more UCS server(s) must be installed firstly.

There are several possible different installation scenarios. In principle, OXASE/OXSE4UCS can be installed on all UCS domain controller server roles: DC master, DC backup or DC slave. Installation on the server roles member server or base system is not currently possible.

To start, the UCS systems are installed as usual with UCS 2.4. If several systems are in the UCS domain, a check must be performed that the join procedure has been run on all servers. This is usually done at the end of the installation procedure. Further information on the installation of UCS can be found in the UCS manual: http://www.univention.de/dokumentation.html.

The password-protected Open-Xchange repository must be integrated on all the systems where OXASE/OXSE4UCS packages are to be installed. The following Univention Configuration Registry variables (UCR variables) can be used to do this:

$ export LDBUSER=”myusername” LDBPASS=”secret”
$ ucr set repository/online/component/ox/server=software.open-xchange.com \

	repository/online/component/ox=enabled \

	repository/online/component/oxseforucs/password=”$LDBPASS” \                                                                                                                                   
	repository/online/component/oxseforucs/version=current \                                                                                                                                    
	repository/online/component/oxseforucs=enabled

The access data (myusername and secret) are created when the Open-Xchange licence is activated and must be adapted here accordingly.

Installation on a DC master

When installing OXASE/OXSE4UCS on a DC master, only the univention-ox-meta-singleserver package requires installing. This can be performed via the Univention Management Console or on the command line:

 $ univention-install univention-ox-meta-singleserver

The univention-ox-meta-singleserver package automatically installs packages for the filtering of spam and viruses at the same time. If this is not required, the univention-ox and univention-mail-cyrus-ox packages can be installed instead of the univention-ox-meta-singleserver package.

Installation on a dedicated DC slave

In this installation scenario, the DC slave system acts as a standalone Open-Xchange groupware server. To start, the univention-ox-directory-integration package must be installed on the DC master in order to initiate integration in the UCS management system.

DEBIAN_FRONTEND=noninteractive apt-get \
	 -o DPkg::Options::=--force-confold -y --force-yes \
	 install univention-ox-directory-integration

The univention-ox-meta-singleserver package is installed on the DC slave which is to be used as the groupware server. In addition, the join scripts must also be run following the installation:

DEBIAN_FRONTEND=noninteractive apt-get \
	 -o DPkg::Options::=--force-confold -y --force-yes \
	 install univention-ox-meta-singleserver

univention-run-join-scripts

The univention-ox-meta-singleserver package automatically installs packages for the filtering of spam and viruses. If this is not required, the univention-ox and univention-mail-cyrus-ox packages can be specified instead of the univention-ox-meta-singleserver package.

Installation in a distributed environment

When installing a distributed environment, integration in the UCS management system must be performed firstly by installing univention-ox-directory-integration.

DEBIAN_FRONTEND=noninteractive apt-get \                                         
	 -o DPkg::Options::=--force-confold -y --force-yes \                             
	 install univention-ox-directory-integration                                      

The following services can then be distributed on the other UCS systems:

  • IMAP server and optionally spam and virus filtering (univention-mail-cyrus-ox and optionally univention-mail-antispam-ox and univention-antivir-mail)
  • MySQL server (mysql-server)
  • OX instance (univention-ox)


MySQL server

The MySQL server is installed by installing the mysql-server package.

apt-get install mysql-server                                                

The configuration of the MySQL server should be set so that the MySQL service can be accessed via the external network interfaces. To do this, for example, the bind-address option can be set to 0.0.0.0 in the MySQL configuration file /etc/mysql/my.cnf.

bind-address 0.0.0.0                                                             

After the change, the MySQL service needs to be restarted:

/etc/init.d/mysql restart

In addition, the OX instances must be authorized to access the database. The following gives an example, which must be adapted to the environment at hand.

$ mysql                                                                            
mysql> GRANT ALL PRIVILEGES ON *.* TO \                                          
 'openexchange'@'ox-instance1.example.com' \                                       
 IDENTIFIED BY 'secret';                                                         
mysql> GRANT ALL PRIVILEGES ON *.* TO \                                          
 'openexchange'@'ox-instance2.example.com' \                                       
 IDENTIFIED BY 'secret';                                                         
mysql> GRANT ...                                                                 
mysql> FLUSH PRIVILEGES;                                                         
mysql> exit                           
$

Active OX instance

The univention-ox package must be installed on the active OX instance.

DEBIAN_FRONTEND=noninteractive apt-get \                                         
	 -o DPkg::Options::=--force-confold -y --force-yes \                             
	 install univention-ox                                                           

Then certain environment variables must be set to ensure that the join scripts run later receive the corresponding permissions. The following gives an example, which must be adapted to the environment at hand. The variable OXDB defines the MySQL server to be used by the OX instance. The corresponding password should be saved in the variable OXDBPW. The standard IMAP server must be specified in the variable OXIMAPSERVER. Hostnames need to be specified as fully qualified domain names (FQDN). It is not possible to use IP addresses.

export HISTIGNORE="export*"                                                      
export OXDB=oxdbserver.example.com                                                 
export OXDBPW="secret"                                                           
export OXIMAPSERVER=oximapserver.example.com                                        

Then the join scripts need to run:

univention-run-join-scripts

Finally, the environment variable OXDBPW with the password can be unset using the following command:

unset OXDBPW

IMAP server

The IMAP server is installed by installing the univention-mail-cyrus-ox package.

DEBIAN_FRONTEND=noninteractive apt-get \                                         
	 -o DPkg::Options::=--force-confold -y --force-yes \                             
	 install univention-mail-cyrus-ox                                                                              

The spam check via spamassassin can be installed and activated by installing the univention-mail-antispam-ox package:

apt-get install univention-mail-antispam-ox                                          

The virus check via amavis and clamav can be installed and activated by installing the univention-antivir-mail package.

apt-get install univention-antivir-mail                                      

A check should then be performed to see whether all join scripts have been run successfully:

univention-run-join-scripts

Additional passive OX instances

Firstly, the univention-ox package must also be installed on the additional passive OX instances.

DEBIAN_FRONTEND=noninteractive apt-get \                                         
	 -o DPkg::Options::=--force-confold -y --force-yes \                             
	 install univention-ox                                                                                                                     

Then the settings can be copied from the active OX instance. This can be done, for example, using the following command:

rsync -essh -a root@ox-instance1.example.com:/opt/open-xchange/. /opt/open-xchange/

The FQDN of the current computer must be entered in the /opt/open-xchange/etc/groupware/usm.properties file:

com.openexchange.usm.ox.url=ox-instance2.example.com

The FQDN of the current computer must also be entered in the /opt/open-xchange/etc/authplugin.properties file:

LDAP_HOST=ox-instance2.example.com

Finally, the groupware must be restarted on the passive OX instance:

/etc/init.d/open-xchange-admin restart
/etc/init.d/open-xchange-groupware restart

OXtender for Business Mobility

The Open-Xchange OXtender for Business Mobility is an optionally available component for OXASE/OXSE4UCS which enables the connection of mobile devices. The repository must be activated for it to be possible to install the corresponding packages:

export LDBUSER=ldbuser LDBPASS=lsbpass
ucr set repository/online/component/oxmobility/server=software.open-xchange.com \
	repository/online/component/oxmobility/prefix=OX6/OXSEforUCS \
	repository/online/component/oxmobility/username=$LDBUSER \
	repository/online/component/oxmobility/password=$LDBPASS \
	repository/online/component/oxmobility/version=2.2,2.3 \
	repository/online/component/oxmobility=enabled

apt-get update

Installing the univention-ox-usm-ox package installs the Oxtender for Business Mobility on the OXASE/OXSE4UCS system.

apt-get install univention-ox-usm-ox

If the target system is neither a DC master nor a DC backup system, the univention-ox-usm-udm package should also be installed on the DC master.

apt-get install univention-ox-usm-udm

Updating

Please do not use the UMC Online Update module as in some cases this might cause an unavailability of the UMC. We strongly recommend to use the console for updating the system. To do so proceed as follows.

To update a UCS 2.2 system with OXASE/OXSE4UCS 6.12 or 6.14 to UCS 2.3, the following variables must be set before the update.

ucr set repository/online/component/ox/version=2.2,2.3 \
        repository/online/component/oxseforucs/version=2.2,2.3

To apply the update, run the command

univention-updater net

Administration

User and group management

New users and groups can be created using the Univention Directory Manager (UDM). The UDM can be accessed on the DC master via a web browser at https://<IP-Adresse des DC Master>/udm/. It is possible to log in as the Administrator user using the password specified during the installation.

When creating a user, the open-xchange groupware account user template should be selected. This preselects all Open-Xchange specific settings.

System messages

The mail/alias/root UCS variable must be set so that system messages can be delivered. To do this, either a new account can be created or, alternatively, oxadmin@DOMAIN is provided for this purpose:

ucr set mail/alias/root=oxadmin@example.com
newaliases
/etc/init.d/postfix reload

It is possible to log in as the oxadmin user in the Open-Xchange web interface using the password from the /etc/ox-secrets/context10.secret file.
