The missing symbols are a non-issue; dpkg-shlibdeps warns about these
because it has no way of knowing what symbols in a plugin are supposed to
be resolved by the caller, which is the case here.

Can you help with fixing the Samba build rules so that it will actually
*use* the system talloc library if present?  I can't see any way to specify
this; the only choices I see are to build against the static in-tree lib,
build against the shared in-tree lib, or link the individual object files
directly without first making a lib, there's no way to tell the build rules
to *not* build libtalloc and instead look for it in the system path.  (If I
could get that working, we would use that solution for both libtalloc and

Doesn't actually work, as mentioned in my previous mail.

Actually, no; it has an soname, so what needs to be provided is
libtalloc.so.0.  The samba build rules are buggy in this regard as well,
since they install each lib under the "*.so" name, and we have to rename it
in the Debian packaging to get it under the right name for the runtime

These would never belong in the samba-common package.  We need packaging
that's future-proofed against ABI changes, so each shared library we ship
will get its own package.
