OpenLDAP Server Installation
After downloading the program, launch the installer, select your
language, accept the license and choose the target installation
directory. The default directory is:
c:\Program Files\OpenLDAP
.
When the
Select Components
dialog box appears, select
install
BDB-tools
and
install OpenLDAP-slapd as NT service
, as shown in
the diagram, below:
OpenLDAP Server Configuration
The main OpenLDAP configuration file, slapd.conf, has to be
customized before launching the server. The modifications to the
configuration file will do the following:
• Specify the Unicode data directory. The default is
./ucdata
.
• Choose the required LDAP schemas. The core schema is
mandatory.
• Configure the path for the OpenLDAP
pid
and
args
start up files.
The first contains the server pid, the second includes command
line arguments.
• Choose the database type. The default is
bdb
(Berkeley DB).
• Specify the server suffix. All entries in the directory will have this
suffix, which represents the root of the directory tree. For example,
with suffix
dc=tripplite,dc=com
, the fully qualified name of all
entries in the database will end with dc=tripplite,dc=com.
• Define the name of the administrator entry for the server (
rootdn
),
along with its password (
rootpw
). This is the server’s super user.
The rootdn name must match the suffix defined above. (Since all
entry names must end with the defined suffix, and the rootdn is
an entry)
An example configuration file is provided in the figure, below:
Starting the OpenLDAP Server
To start the OpenLDAP Server, run
slapd
(the OpenLDAP Server exe-
cutable file) from the command line.
slapd
supports a number of
command line options, the most important option is the
d
switch
that triggers debug information. For example, a command of
slapd
-d 256
would start OpenLDAP with a debug level of 256, as shown
in the following screenshot:
Note:
For details about
slapd
options and their meanings, refer to
the OpenLDAP documentation.
Customizing the OpenLDAP Schema
The schema that
slapd
uses may be extended to support additional
syntaxes, matching rules, attribute types, and object classes. In the
case of the B020-Series KVM Switch, the B020-Series KVM Switch
User
class and the
permission
attribute are extended to define a
new schema. The extended schema file used to authenticate and
authorize users logging in to the B020-Series KVM Switch is shown
in the figure, below:
