<refsect1 id='querying'>
	<title>Querying Domain Information</title>

	<para><command>adcli info</command> displays discovered information

<programlisting>
$ adcli info domain.example.com
...
</programlisting>

<programlisting>
$ adcli info --domain-controller=dc.domain.example.com
...

	<para><command>adcli info</command> will output as much information as
	it can about the domain. The information is designed to be both machine
	and human readable. The command will exit with a non-zero exit code
	if the domain does not exist or cannot be reached.</para>

	<para>To show domain info for a specific domain controller use the
	<option>--domain-controller</option> option to specify which domain
	controller to query.</para>

	<para>Use the <option>--verbose</option> option to show details of how
	the domain is discovered and queried. Many of the global options, in
	particular authentication options, are not usable with the
	<command>adcli info</command> command.</para>
</refsect1>

<refsect1 id='joining'>
	<title>Joining the Local Machine to a Domain</title>

	<para><command>adcli join</command> creates a computer account in the
	domain for the local machine, and sets up a keytab for the machine.
	It does not configure an authentication service (such as
	<command>sssd</command>).</para>
