\begin{ucsTabbox}{'[Client devices]' tab}
This tab is only found on thin client computers.

\ucsTabentry{Activate access to client devices}
Selecting this checkbox allows access from this thin client to
peripherals such as CD-ROM and disk drives connected to this thin
client.
\end{ucsTabbox}


\begin{ucsTabbox}{'[Sound]' tab}
This tab sets up the sound output. It is only shown on thin client
computers.

\ucsTabentry{Sound enabled}
Selecting this checkbox activates sound support. As standard sound
support is not activated.

\ucsTabentry{Sound module}
Normally the setting \emph{auto detect} provides an appropriate driver
module for sound support automatically. Alternatively, a driver module
for the sound card can be specified manually in the selection list.
\end{ucsTabbox}


\begin{ucsTabbox}{'[Thin client]' tab}
This tab is only found on thin client computers. Changed values will
apply from the next time the thin client is booted. Some input fields
require a server to be specified. To avoid problems during the
resolution of names, the fully qualified domain name should always be
entered. In addition, it must be verified it can be resolved in an IP
address.

\ucsTabentry{Authentication server}
The users who log on to this thin client authenticate themselves on
the servers specified here.

If nothing is entered here and a user tries to log on, the system
establishes all Kerberos servers using service records in the DNS. The
system then attempts to authenticate the user using one of these
Kerberos servers.

\ucsTabentry{File server}
The file server for the thin client can be entered and edited
here. The \ucsURL{/home} directory is mounted on the thin client from
this server when a user logs on, for whom no mountable share is
defined (see also \ucsMenuEntry{POSIX (Linux/UNIX)} tab in
Chapter~\ref{module:user:benutzerverwaltung:karteikarte-linux-unix} on
page
\pageref{module:user:benutzerverwaltung:karteikarte-linux-unix}). If a
mountable share is entered for the user, it is mounted. There
is no need to enter the file server if a mountable share is entered
for all users. Users can not log on without a mounted home directory.

\ucsExclamation\ucsAttention{If the user data should be saved on the
  file server by the Linux terminal server, the file server must be
  mounted on the terminal server manually! It goes without saying that
  this is not necessary when the terminal server and the file server
  are in fact the same computer. Windows terminal servers find out
  where a user's home directory is via the log-in server.}

If more than one file server is entered the thin client tries to
connect the file server at the top in the \emph{Entries} list
first. If this fails, it tries the next one, etc.

\ucsTabentry{Linux terminal server}
One or more Linux terminal servers can be added or edited here for the
thin client.

A Linux terminal server is a server which provides the programs for
the Linux workstation on which the \emph{Terminal services} component
is installed.

The decision of which server is used when multiple entries exist is
taken automatically by UCS using a load balancing mechanism.

\ucsTabentry{Windows terminal server}
If the users should be provided with a Windows environment on this
thin client, a server must be entered in this input field which is
to provide this Windows interface.

If several Windows terminal servers are entered, the first one in the
list will be used.

\ucsTabentry{Windows domain}
If the users should be provided with a Windows workstation on this
thin client, the name of the Windows domain where the user is
registered is to be entered in this input field.

\ucsNote{As standard, a \emph{default-settings} policy is created,
  which is valid for the whole domain. Computers on which the
  \emph{Terminal services} component is installed enter themselves
  automatically as Linux terminal servers in the policy when a domain
  is joined; computers on which the \emph{univention-nfs} package is
  installed enter themselves as file servers. The package is installed
  on all UCS servers (DC masters, backups and slaves) as standard.}
\end{ucsTabbox}


\begin{ucsTabbox}{'[Autostart]' tab}
\emph{This tab is only available on thin clients, managed clients and mobile clients.}

Thin clients can be operated without a log-in mask to start a Citrix
client automatically and exclusively every time the computer is switched
on, for example.

\ucsTabentry{Autostart session}
The name of the autostart script should be entered here which should
be started the next time the client is started. An autostart script is
a shell script in which programs are entered which are started each
time the user \ucsName{autostart} logs in automatically. This script
must be saved under
\ucsURL{/var/lib/univention-client-root/etc/gdm/Autostart/} on the
thin client's terminal server. On a managed or mobile client it is
saved under \ucsURL{/etc/gdm/Autostart/}.

Examples for integrating the Citrix client, \ucsCommand{nxclient} or
\ucsCommand{rdesktop} in autostart scripts can be found on a UCS
server with installed thin client infrastructure package
(\ucsName{univention-thin-client}) under
\ucsURL{/var/lib/univention-client-root/etc/gdm/Autostart/}.
