<title>DESCRIPTION</title>
<para>The idmap_hash plugin implements a hashing algorithm used to map
SIDs for domain users and groups to 31-bit uids and gids, respectively.
This plugin also implements the nss_info API and can be used
to support a local name mapping files if enabled via the
"winbind normalize names" and "winbind nss info"
parameters in smb.conf.
