hi list, I tried to setup samba/winbind server with the idmap ldap backend, and I think the samba howto is wrong on that part : http://us3.samba.org/samba/docs/man/Samba-HOWTO-Collection/idmapper.html#id2600225 As described in the howto it couldn't work : /etc/nsswitch.conf passwd: files ldap shadow: files ldap group: files ldap hosts: files wins the correct values are : /etc/nsswitch.conf passwd: files winbind shadow: files winbind group: files winbind hosts: files wins because the ldap tree filled by winbind contains only the SID to id/gid informations not the uid informations so the nss_ldap search will failed.
