The Samba-Bugzilla – Bug 4551
Samba Client Tools do not support IPv6
Last modified: 2007-05-12 23:20:09 UTC
Client tools do not support IPv6 addresses in configuration or commands. Neither do they support SMB over IPv6.
Client tools should support IPv6 over port 455 (no need for NetBIOS). WINS is not IPv6 enabled so does not need to be supported.
Also client should support AD join etc over IPv6.
Let me know if I can help with IPv6 info or testing.
This looks just like #4572 to me.
