When building and installing, it looks like all other binaries are linked twice:
once with regular names, like bin/default/source3/libnetapi.so*, and also with .inst,
like bin/default/source3/libnetapi.inst.so*.

But libsmbldap.so* is linked only once, - there's no .inst suffix for it.

But I don't see a difference between the two declarations in wscript.build, both
seems to be using similar bld.SAMBA3_LIBRARY() constructs.

There are a few other files like this, with missing RUNPATH and without .inst
link, but these are private:

  /usr/lib/x86_64-linux-gnu/samba/libads-samba4.so.0
  /usr/lib/x86_64-linux-gnu/samba/libnet-keytab-samba4.so.0
  /usr/lib/x86_64-linux-gnu/samba/libsamba-modules-samba4.so.0
  /usr/lib/x86_64-linux-gnu/samba/libsmbldaphelper-samba4.so.0

I still can't figure out how it all is being built...

For me, a "fix" would be to manually add the missing RUNPATH with patchelf
or chrpath, but this is.. a very hackish temporary bandaid.
