I have had a similiarly problem with one machine which has done an auto 
update yesterday evening. Update was from samba_3.6.6-6+deb7u1 to 
samba_3.6.6-6+deb7u2. Package server is ftp.de.debian.org

The package.list files in /var/lib/dpkg/info/ did _not_ list any 
binaries :-( . And yes, no smbd, nmbd or winbindd was in /usr/sbin/

So I downgraded to samba_3.6.6-6+deb7u1 which doesn't help, but sets the 
apt database to the last known good version. Then I have downloaded all 
packages manually via wget and installed them via dpkg -i package.deb

The required packages for this installation are:
samba-tools_3.6.6-6+deb7u1_i386.deb
libsmbclient_3.6.6-6+deb7u1_i386.deb
samba_3.6.6-6+deb7u1_i386.deb
smbclient_3.6.6-6+deb7u1_i386.deb
libwbclient0_3.6.6-6+deb7u1_i386.deb
samba-common-bin_3.6.6-6+deb7u1_i386.deb
winbind_3.6.6-6+deb7u1_i386.deb

Today at 23:00 cet the next update is scheduled. I hope that this does 
not happen again. Otherwise I will force apt to stay on samba version 
3.6.6-6+deb7u1.
