	<title>DESCRIPTION</title>

	<para>This tool is part of the <citerefentry><refentrytitle>samba</refentrytitle>
	<manvolnum>7</manvolnum></citerefentry> suite.</para>

	<para>The pdbedit program is used to manage the users accounts
	stored in the sam database and can only be run by root.</para>

	<para>The pdbedit tool uses the passdb modular interface and is
	independent from the kind of users database used (currently there
	are smbpasswd, ldap, nis+ and tdb based and more can be added
	without changing the tool).</para>

	<para>There are five main ways to use pdbedit: adding a user account,
	removing a user account, modifying a user account, listing user
	accounts, importing users accounts.</para>
</refsect1>

		<varlistentry>
		<term>-L|--list</term>
		<listitem><para>This option lists all the user accounts
		present in the users database.
		This option prints a list of user/uid pairs separated by
		the ':' character.</para>

		<varlistentry>
		<term>-v|--verbose</term>
		<listitem><para>This option enables the verbose listing format.
		It causes pdbedit to list the users in the database, printing
		out the account fields in a descriptive format. Used together
		with -w also shows passwords hashes.</para>

		<manvolnum>5</manvolnum></citerefentry> for details).
		Instead used together with (-v) displays the passwords
		hashes in verbose output.</para>
