To be honest I don't fully understand what private libraries are. Does this mean that wbclient gets compiled to a different so-name and loaded via it's rdpath? 

Is libwbclient from samba4 backward compatible to the one provided by samba3.6? 
If so shouldn't the packet provide a new libwbclient1 and replace the one from 3.6. The provides and requires of the deb packet should require the new libwbclient and old programms linked against libwbclient from samba 3.6 would run with the new wbclientlib from samba4.
