Hi all, I have the following situation: 1 PDC Windows NT 4.0. 1 Samba server Member Domain connect to PDC via winbind. 1 Rsync server connect to Samba server Member Domain. Now, I would like to know how can I share SID mapping on UID/GID in Samba because I have to install another Samba on Rsync server and in case of emergency switch to this one. Maybe I have to use LDAP server as backend in actually Samba server, and connect future Samba/Rsync server to this one but I don't understand how can I do it and if it is correct with LDAP or does it works only with an AD server? Can I use winbind to ask to the NT/PDC and populate an LDAP containerin the same server? Can anyone help me? Thanks a lot. Tito.
