Can you replace the system libwbclient with the one from 3.5.0 and retry? Volker
Yes, that was it exactly. All of the 3.5.0 libraries were installed in /usr/lib/samba, while (at least) nmbd and smbd were using libraries in /usr/lib. I did configure with --libdir=/usr/lib/samba Thanks for the very rapid response. Samba is 80% of why I started using linux back in 1999, and it's still my favorite part from a just-works perspective. You guys are great.
