UCS 2.4 - Univention

g) Base system
Attention:
3.2 Text-based Installation
The first system to be installed on a UCS domain should always be a domain controller master.
The installation of further UCS systems requires a domain controller master to be running during
installation. The sole exception to this is the base system system role, which can be installed
without a connection to a domain controller master.
The system roles are described in Chapter 2.1.
9. Domain settings
System name is the name by which the host is to be accessible within the network. The name
must consist of a combination of the following characters: letters a-z in lower case, numerals 0-9,
hyphens, and underlines. The host name has to begin with a letter and must not be longer than 15
characters.
Domain name is the name of the UCS domain, for example, firma.de.
Once the domain name is set, the fields LDAP base and Windows domain will be assigned by
derived values. If the LDAP basis is to be changed, the name conventions for DNs have to be
observed. The basis DN has to begin with ’cn=’, ’dc=’, ’c=’, ’l=’, or ’o=’. Basis DNs violating these
conventions will be rejected.
The name of the Windows domain may have a maximum length of 15 characters; it may consists of
letters, numerals and hyphens exclusively. The entry field LDAP base appears solely in the system
role of Domain Controller Master.
Root password is the password for the user ’root’. This password is also set for the user ’Administra-
tor’. The user ’Administrator’ is used for joining Windows clients into the UCS domain. In subsequent
operation, the passwords of the users ’root’ and ’Administrator’ can be managed independently. The
password is entered for a second time in the final entry field. This double input is necessary to avoid
spelling errors since the entered characters are not displayed on the screen, see 3.2.
For security reasons, the root passwords needs to consist of at least eight characters.
10. Partitioning dialog
This menu is used for partitioning the existing hard drives. It is recommended to use at least two
partitions - one for the root file system, and one for the swap area which is used internally by Linux.
At the first opening of this menu, the installer offers automatic partitioning of the system. On
confirmation, the installer displays a partitioning proposal in which all the existing hard drives are
newly partitioned and formatted using the Logical Volume Manager (LVM).
Attention:
All the data stored on these hard drives will be lost during this process! Should the proposed parti-
tioning be undesirable, it can be rejected by pressing the F5 function key. The disk space of external
storage media, such as USB sticks and USB hard drives, is also included in the automatic partitioning
procedure, so these media should be disconnected if necessary.
The properties of the detected drives, existing partitions, and LVM media (name, range of a partition,
type, formatting, directory in which the partition is to be mounted, and size in MB) are displayed in a
table. See Illustration 3.3.
