Why are you saying that dbwrap*.so depends on the credentials library?

In the current build, I haven't seen anything like that:

$ dpkg -s samba-common-bin |grep credentials
$ dpkg -s samba-common-bin |grep Depends    
Depends: samba-common (= 2:4.0.6+dfsg-1~kali1), python-samba, python2.7
$ 

But the above Depends line is strange, it looks like it would be missing
${shlibs:Depends} since we have no libc6 dependency and so on.

Analysing the package more closely, I found out that
/usr/lib/x86_64-linux-gnu/samba/libmsrpc3.so effectively depends on
libsamba-credentials.so.0. But that the sole file in samba-common-bin
which depends on that library.

I'm not quite sure what's the best approach. Splitting all libraries
in /usr/lib/x86_64-linux-gnu/samba/ in individual packages seems overkill.
But at the very least we need to put them in packages without
executables in /usr/bin/ to achieve multi-arch support. I'll call this
theoretical package "samba-libs" for now.

The solution that I would recommend is the following:
1/ put automatic dependencies of "samba-libs" in the "Recommends" or
   "Suggests" fields
2/ create symbols files for each private library that will add the
   required hard dependency on those external libraries
   (this will require some serious scripting if we want to automate it)

That way we don't have Depends loop, and anyone linking to one of the
library in samba-libs still gets a reliable (and accurate) dependency.
The samba-libs-dev package would have to ensure that all libraries
are installed though, otherwise "ld" might fail at build time.

Ack.
