        <para>
            The file has an ini-style syntax and consists of sections and
            parameters. A section begins with the name of the section in
            square brackets and continues until the next section begins. An
            example of section with single and multi-valued parameters:
            <programlisting>
                <replaceable>[section]</replaceable>
                <replaceable>key</replaceable> = <replaceable>value</replaceable>
                <replaceable>key2</replaceable> = <replaceable>value2,value3</replaceable>
            </programlisting>
        </para>

        <para>
            The data types used are string (no quotes needed), integer
            and bool (with values of <quote>TRUE/FALSE</quote>).
        </para>

        <para>
            A line comment starts with a hash sign (<quote>#</quote>) or a
            semicolon (<quote>;</quote>)
        </para>

        <para>
            All sections can have an optional
            <replaceable>description</replaceable> parameter. Its function
            is only as a label for the section.
        </para>

        <para>
            <filename>sssd.conf</filename> must be a regular file, owned by
            root and only root may read from or write to the file.

            <para>
                Individual pieces of SSSD functionality are provided by special
                SSSD services that are started and stopped together with SSSD.
                The services are managed by a special service frequently called
                <quote>monitor</quote>. The <quote>[sssd]</quote> section is used
                to configure the monitor as well as some other important options
                like the identity domains.

                                at the same time, but at least one

                                DNS resolver. By default, we will attempt to
                                use inotify for this, and will fall back to
                                polling resolv.conf every five seconds if
                                inotify cannot be used.

                            For example, if the domain's entry_cache_timeout
                            is set to 30s and entry_cache_nowait_percentage is
                            set to 50 (percent), entries that come in after 15
                            seconds past the last cache update will be
                            returned immediately, but the SSSD will go and
                            update the cache on its own, so that future
                            requests will not need to block waiting for a
                            cache update.

                            represent a percentage of the entry_cache_timeout
                            for each domain. For performance reasons, this
                            percentage will never reduce the nowait timeout to
                            less than 10 seconds.

                            Determines if a domain can be enumerated. This
                            parameter can have one of the following values:
                        </para>
                        <para>
                            TRUE = Users and groups are enumerated

                        <para>
                            Note: Enabling enumeration has a moderate
                            performance impact on SSSD while enumeration
                            is running. It may take up to several minutes
                            after SSSD startup to fully complete enumerations.
                            During this time, individual requests for
                            information will go directly to LDAP, though it
                            may be slow, due to the heavy enumeration
                            processing.

                        <para>
                            While the first enumeration is running, requests
                            for the complete user or group lists may return
                            no results until it completes.

                        <para>
                            Further, enabling enumeration may increase the time
                            necessary to detect network disconnection, as
                            longer timeouts are required to ensure that
                            enumeration lookups are completed successfully.
