<samba:parameter name="passwd program" context="G" type="string" advanced="1" developer="1" xmlns:samba="http://www.samba.org/samba/DTD/samba-doc"> <description> <para>The name of a program that can be used to set UNIX user passwords. Any occurrences of <parameter moreinfo="none">%u</parameter> will be replaced with the user name. The user name is checked for existence before calling the password changing program.</para> <para>Also note that many passwd programs insist in <emphasis>reasonable </emphasis> passwords, such as a minimum length, or the inclusion of mixed case chars and digits. This can pose a problem as some clients (such as Windows for Workgroups) uppercase the password before sending it.</para> <para><emphasis>Note</emphasis> that if the <parameter moreinfo="none">unix password sync</parameter> parameter is set to <constant>yes </constant> then this program is called <emphasis>AS ROOT</emphasis> before the SMB password in the smbpasswd file is changed. If this UNIX password change fails, then <command moreinfo="none">smbd</command> will fail to change the SMB password also (this is by design).</para> <para>If the <parameter moreinfo="none">unix password sync</parameter> parameter is set this parameter <emphasis>MUST USE ABSOLUTE PATHS</emphasis> for <emphasis>ALL</emphasis> programs called, and must be examined for security implications.
