<para>
This manual page describes the configuration of LDAP
domains for
<citerefentry>
<refentrytitle>sssd</refentrytitle>
<manvolnum>8</manvolnum>
</citerefentry>.
For detailed syntax reference, please refer to
<citerefentry>
<refentrytitle>sssd.conf</refentrytitle>
<manvolnum>5</manvolnum>
</citerefentry> manual page, section <quote>FILE FORMAT</quote>
</para>
<para>
There can be more than one LDAP domain configured with SSSD.
</para>
<para>
If you want to authenticate against an LDAP server TLS/SSL is
required. <command>sssd</command> <emphasis>does not</emphasis>
support authentication over an unencrypted channel. If the LDAP
server is used only as an identify provider, an encrypted channel
is not needed.
</para>
</refsect1>
<refsect1 id='file-format'>
<title>CONFIGURATION OPTIONS</title>
<para>
All the common configuration options for SSSD domains apply
for LDAP domains, too. See the

rfc2307bis

how group memberships are recorder in the server.
With rfc2307 group members are listed by name in an
attribute called <emphasis>memberUid</emphasis>.
With rfc2307bis grpoup members are listed by DN and
stored in an attribute called
<emphasis>member</emphasis>.
