Success!
After updating samba with the one in the 1.3 repositories (since i'm using 1.2 from the .iso and I chose to KEEP my samba.conf instead of using the repo version) I am able to connect to an eBox domain from a Windows 7 64bit client
and browse shares.
Turns out that the share and now mapped drive are able to be seen in the file explorer but cannot be accessed (not found).
I also tried to add the pdf printer and it failed with an 0x00000000d error.
So I can only login to the domain now. The shares worked for a few minutes i even transferred files.
After a first reboot I was greeted with a dialog box asking me to reboot to apply changes? What changes, I'm already connected to the domain!
The initial logon is very long. after I enter user and pass, the system waits about 90sec+ before displaying desktop.
Subsequent reboot and logon is about 60sec+ before desktop. Is this a roaming profile thing or just Windows 7? I do not have roaming profiles selected.
When I "return" the machine I will note the time between authentication and desktop display on a SBS2003 domain.
I cannot test printing with my home setup. HP1000 needs firmware loaded every time and I don't care enough to get that working. All the work machines are 5 years newer than it.
Hope this helps someone. I can test for another day if someone needs something.
Thanks J. A. Calvo and the rest of the eBox team.
best,
