Hi Roberto, Just in case this was not known: it might be possible to cross-check your work with what Ubuntu does. Rember, they have in 12.04 samba as well from 3.6. branch. Though updated to 3.6.25 + patches, but that still might help you.
It's a good source to cross-check as well for future samba updates. Regards and hope this helps, Salvatore
