The UCS web interface can be opened on any UCS system via the URL
https://servername/. Alternatively, access is also possible via the server’s
IP address. Under certain circumstances it may be necessary to access the
services over an insecure connection (e.g., if no SSL certificates have been
created for the system yet). In this case,
http must be used instead of
https in the URL. In this case, passwords are sent over the network in plain

4.1.3. Switching between dark and light theme for UCS web interfaces#
All UCS web interfaces have a dark and a light theme that can be switched between with
the Univention Configuration Registry Variable
ucs/web/theme. The value of
corresponds to a CSS file under
the same name (without file extension). For example, setting
light will use
/usr/share/univention-web/themes/light.css as theme for all UCS web interfaces.
4.1.4. Creating a custom theme/Adjusting the design of UCS web interfaces#
To create a custom theme it is advised not to edit
the changes may be overwritten when upgrading UCS. Instead copy one of
these files to e.g.
set the Univention Configuration Registry Variable
/usr/share/univention-web/themes/light.css contain the same list of CSS
variables. These variables are used in other
CSS files and are the supported layer of configurability for UCS web interfaces. The
names and current use case for these variables will not change between UCS
upgrades but new ones may be added.
Some UCS web interfaces import their own local
custom.css file which can be
used to further adjust the design of that page. These are
(Login via single sign-on) and
/usr/share/univention-portal/custom.css (UCS portal page). The
files are empty when installing UCS and are not modified when installing any UCS
update. Be aware though that a given CSS selector
may break when installing any UCS update.
