<samba:parameter name="idmap backend" context="G" advanced="1" developer="1" hide="1" xmlns:samba="http://samba.org/common"> <listitem> <para> The purpose of the idmap backend parameter is to allow idmap to NOT use the local idmap tdb file to obtain SID to UID / GID mappings, but instead to obtain them from a common LDAP backend. This way all domain members and controllers will have the same UID and GID to SID mappings. This avoids the risk of UID / GID inconsistencies across UNIX / Linux systems that are sharing information over protocols other than SMB/CIFS (ie: NFS). </para> <para>Default: <command moreinfo="none">idmap backend = <empty string></command></para> <para>Example: <command moreinfo="none">idmap backend = ldap:ldap://ldapslave.example.com</command></para> </listitem> </samba:parameter>
