A short update:
Using a samba client, i CAN access the dfs shares, so it seems to be a
problem with Win7 doing things differently. I've tried to do some capturing
for the following

1. Win7 client (domain member) FAIL
2. samba client (domain member, smbclient from one of the DCs) SUCCESS
3. samba client v3.6.3 (non-domain member) SUCCESS
4. samba client v4.0 alpha18 (non domain member) FAIL

Attached are the wireshark logs. One thing that is immediately apparent is
that the clients that connect using SMB are the *only ones* that succeed:
* dionysos-success-samba-3.6.3 -> SMB, samba 3.6.3
* samba4-nondomain-success-samba4.0.5 ->SMB, samba 4.1.0pre1-GIT-392b01f

The other clients fail:
* win7-fail  -> SMB2, Win7 SP1 Enterprise 64-bit
* dionysos-fail-samba4.0alpha18 -> SMB, samba 4.0 alpha18

[UPDATE] just tried setting the SMB version on win7 to 1, following
commands specified here:
Alas, still no luck.
