	<para>This setting controls the minimum protocol version that the
	client will attempt to use.</para>

	<para>Normally this option should not be set as the automatic
	negotiation phase in the SMB protocol takes care of choosing
	the appropriate protocol unless you connect to a legacy SMB1-only server.</para>

	<para>See <related>client max protocol</related> for a full list
	of available protocols.</para>

	<para>IPC$ connections for DCERPC e.g. in winbindd, are handled by the
	<smbconfoption name="client ipc min protocol"/> option.</para>

	<para>Note that most command line tools support
	--option='client min protocol=NT1', so it may not be required to
	enable SMB1 protocols globally in smb.conf.</para>
