+1 from me.
As some of you know, we will ship Samba 4 with the next major release of UCS
in a few weeks. We made a lot of good progress in the last few month,
specially with the help of Stefan Metzmacher.
Our status is:
1. The user can choose between Samba 3.5 and Samba 4 in the package selection
of the UCS installation.
2. We will support multiple Samba 4 DCs in one domain.
3. We won't support a mix with Microsoft AD DCs. This is a very big
limitation, but we first want to gather in a plain Samba 4 setup.
4. In UCS we have diffrent system roles similar to the Samba roles. For file
server we will normal use member server and for that we use Samba 3.5 which
joins into the Samba 4 domain.
5. But we also support a file server on the Samba 4 DC. We start the smbd for
file and print services and Metze wrote a vfs module for the sysvol share
6. The bind9 dlz module works fine for us. Windows Kerberos DNS updates are
7. With the S4 Connector we synchronize the data between Samba 4 and OpenLDAP.
8. We write automatically idmap.ldb to get an association between the Samba
users/groups and the POSIX users/groups.
