            LDAP back end supports id, auth, access and chpass providers. If you want
            to authenticate against an LDAP server either TLS/SSL or LDAPS
            is required. <command>sssd</command> <emphasis>does
            not</emphasis> support authentication over an unencrypted channel.
            If the LDAP server is used only as an identity provider, an encrypted
            channel is not needed. Please refer to <quote>ldap_access_filter</quote>

                            Starting with SSSD 1.7.0, SSSD supports multiple
                            search bases using the syntax:

                        <para>

                            Note: It is unsupported to have multiple search
                            bases which reference identically-named objects
                            (for example, groups with the same name in two
                            different search bases). This will lead to
                            unpredictable behavior on client machines.

                            has an empty value namingContexts is used.
                            The namingContexts attribute must have a
                            single value with the DN of the search base of the
                            LDAP server to make this work. Multiple values are

                            Depending on the selected schema, the default
                            attribute names retrieved from the servers may vary.
                            The way that some attributes are handled may also differ.

                                <listitem>

                        <para>
                            The main difference between these schema types is
                            how group memberships are recorded in the server.
                            With rfc2307, group members are listed by name in the
                            <emphasis>memberUid</emphasis> attribute.
                            With rfc2307bis and IPA, group members are listed by DN
                            and stored in the <emphasis>member</emphasis> attribute.
                            The AD schema type sets the attributes to correspond with
                            Active Directory 2008r2 values.

                            performance increase on very complex nestings.

                            determining whether the user's last online login
                            was granted access permission. If they were
                            granted access during their last login, they will
