Creating contexts and users
Now as the whole setup is complete and you already should get a login screen when accessing the server with a webbrowser, we have to setup a context and a default user as the last step of this tutorial.
The mapping defaultcontext will allow you to set this context as the default one of the entire system so that users which will be created within this context can login into Open-Xchange Server without specifying their domain at the login screen. Only one context can be specified as defaultcontext. The oxadmin user that will be created by this command is the default admin of the created context. This account will gather additional functions that are also described in the administration manual. The context id parameter must to be unique and numeric, otherwise the server will complain when you try to create a context. New contexts must be created by the oxadminmaster user, user accounts inside a context are created with the credentials of the contexts oxadmin account. The access-combination-name property defines the set of available modules and functions for users of the context.
$ /opt/open-xchange/sbin/createcontext -A oxadminmaster -P admin_master_password -c 1 \ -u oxadmin -d "Context Admin" -g Admin -s User -p admin_password -L defaultcontext \ -e firstname.lastname@example.org -q 1024 --access-combination-name=all
Create a user for testing purposes:
$ /opt/open-xchange/sbin/createuser -c 1 -A oxadmin -P admin_password -u testuser \ -d "Test User" -g Test -s User -p secret -e email@example.com \ --imaplogin testuser --imapserver 127.0.0.1 --smtpserver 127.0.0.1
Now connect to the server with a webbrowser and login using the credentials testuser / secret.
Log files and issue tracking
Default logging mechanism
Whenever unexpected or erroneous behavior takes place, it will be logged depending on the configured loglevel. All logfiles are stored at the operating systems default location. Events triggered by the Open-Xchange Groupware services are logged to a rotating file open-xchange.log, events triggered by the Open-Xchange Administration service are logged to open-xchange-admin.log. Those files are the very first place to monitor.
$ tail -f -n200 /var/log/open-xchange/open-xchange.log.0 $ tail -f -n200 /var/log/open-xchange/open-xchange-admin.log.0
Alternative logging mechanism using Syslog
Apart from the default file logging mechanism, Open-Xchange supports logging via syslog in using Apache log4j which is a standard framework for application message and error logging. Using log4j makes it possible to directly log to a local or remote syslog daemon or other services. Log4j is highly customizable, please see the Apache log4j  project websites for more information. Note, the default logging locations at /var/log/open-xchange will not be used anymore when installing the log4j bundles, please make sure to check out the configuration guide.
