At the recent CIFS Engineering Workshop at Google, Erion’s David Holder carried out the first ever Windows Server 2008 join of a Samba4 domain over IPv6.
Previously, whilst Samba4 listened on IPv6, only limited functionality worked over IPv6. Whilst file sharing worked over IPv6, many other operations did not. A hacked version of Samba4 now allows Windows Server 2008 to join and function in a Samba4 domain over IPv6. Much work is still to be done before Samba4 is production code, but significant progress has been made towards an IPv6 version of Samba.
