This has been tested against 7.0-RELEASE, 7-STABLE, and -CURRENT as of 10/28/08.

mount_smbfs(8) does not currently support connections over IPv6.  A quick look at the source shows instances of gethostbyname(), and it likely also does not support connecting to port 445 without netbios (as required for cifs/smb over IPv6)

This bug is more important (IMHO) now as Samba has gone mainstream with IPv6 support with the 3.2 release.  
Attempt to mount any IPv6 accessible share with mount_smbfs (requires either Samba 3.2 IPv6 enabled server, or a Windows Server 2003/2008 IPv6 configuration)
