<title>Installation of <application>Open<acronym>LDAP</acronym></application></title>

<para>Install <application>Open<acronym>LDAP</acronym></application> by
running the following commands:</para>

<screen><userinput><command>./configure --prefix=/usr --libexecdir=/usr/sbin \
    --sysconfdir=/etc --localstatedir=/var/lib \
    --disable-debug --enable-ldbm &amp;&amp;
make depend &amp;&amp;
make &amp;&amp;
make test &amp;&amp;
make install</command></userinput></screen>

<sect2>
<title>Command explanations</title>

<para><parameter>--sysconfdir=/etc</parameter>: Sets the configuration file directory to 
avoid the default of <filename class="directory">/usr/etc</filename>.</para>

<para><parameter>--libexecdir=/usr/sbin</parameter>: Puts the server executables in 
<filename class="directory">/usr/sbin</filename> instead of <filename
class="directory">/usr/libexec</filename>.</para>

<para><option>--enable-ldbm</option>: Build <command>slapd</command>
with primary database back end using either <application>Berkeley
DB</application> or
<application><acronym>GNU</acronym> Database Manager</application>.</para> 

<para><option>--disable-debug</option>: Disable debugging code.</para>  

<para><command>make test</command>: Validate correct build of the package.</para>

<sect3><title>Configuration Information</title>

<para>The only configuration needed for 
<application>Open<acronym>LDAP</acronym></application> is 
to run <command>ldconfig</command>. The <acronym>LDAP</acronym> server
can be started by <command>/usr/sbin/slapd</command> as described in 
the man page slapd(8). You can verify that <acronym>LDAP</acronym> is
running with <command>ps aux</command> and you can verify access to the
<acronym>LDAP</acronym> server with the following command:</para>
<screen><userinput><command>ldapsearch -x -b '' -s base '(objectclass=*)' namingContexts</command></userinput></screen>

<para>The correct result is:</para>
<screen><computeroutput># extended LDIF
#
# LDAPv3
# base &lt;&gt; with scope base
# filter: (objectclass=*)
# requesting: namingContexts 
#

#
dn:
namingContexts: dc=my-domain,dc=com

# search result
search: 2
result: 0 Success

# numResponses: 2
# numEntries: 1</computeroutput></screen>

<para>Kill the server with this command:</para>
<screen><userinput><command>kill -INT `cat /var/lib/slapd.pid`</command></userinput></screen>

<para>You are now ready to modify the 
<filename>/etc/openldap/slapd.conf</filename> to be specific to your
installation.</para>

<para><emphasis>Utilizing <application>GDBM</application></emphasis></para>

<para>To utilize <application>GDBM</application> as the database
backend, the "database" entry in <filename>/etc/openldap/slapd.conf</filename>
must be changed from "bdb" to "ldbm".  You can use both by creating an
additional database section in <filename>/etc/openldap/slapd.conf</filename>.</para>

<para><emphasis>Securing your <acronym>LDAP</acronym> server</emphasis></para>

<para>Significant configuration is needed for
<application>Open<acronym>LDAP</acronym></application> to utilize
security features.  The <ulink
url="http://www.openldap.org/doc/admin21/">OpenLDAP 2.1 Administrator's
Guide</ulink> is a good place to start for access control settings,
running as a user other than root and setting a chroot environment.</para>

<para><emphasis>User Tools</emphasis></para>

<para>Data can be added to the <acronym>LDAP</acronym> database via
<command>ldapadd</command>. There are other programs that can use
the database. For more information see the appropriate man page.</para>

<para><emphasis><application>Mozilla</application> Address Directory</emphasis></para>

<para>By default, LDAPv2 support is disabled in the
<filename>slapd.conf</filename> file. Once the database is properly
setup and <application>Mozilla</application> is configured to use the
directory, you must add <option>allow bind_v2</option> to the
<filename>slapd.conf</filename> file.</para>
