Tracking amount in Microtype for textsc won't change

Question

The bibliography style I am using (abbrvdin) uses for the author names all capital letters (like \textsc{}). When tracking in microtype is enabled it adds space between all those letters which doesn't look very good. I searched around and found one solution here.

\SetTracking{encoding=*, shape=sc}{50}

This unfortunatly does not work for me. The space between letters stays the same. What am I doing wrong?

Little more information, I am using: scrreprt, font libertine, bibstyle addrvdin and ngerman babel enabled.

Edit: I switched from libertine back to default font but the spacing didn't change to the value I have provided by SetTracking.

Edit 2: I have found a way around that issue

\microtypesetup{tracking=false}
\bibliography{lit}
\microtypesetup{tracking=true}

But this would also diable tracking in bib in non small capitals. So I would rather have a better solution.

EDIT: I am very sorry that it took me so long to add an example. But here it finally is:

\documentclass[
    12pt,
    paper=a4,
    titlepage=true,
    twoside=true,
    numbers=noenddot,
    parskip=half,
    headings=small,
    draft
]{scrreprt}

\usepackage[
    activate={true,nocompatibility},
    final,
    tracking=true,
    kerning=true,
    factor=1100,
    stretch=10,
    shrink=10
]{microtype}
\SetTracking{encoding=*, shape=sc}{200}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}    
\usepackage[ngerman]{babel}

\usepackage{libertine}
\usepackage[libertine,cmintegrals,cmbraces,vvarbb]{newtxmath}

\usepackage{babelbib}
\usepackage[nottoc]{tocbibind}
\bibliographystyle{abbrvdin}

\begin{document}
    \chapter{Something}
    Blah\dots\cite{carrier,kobayashi}

    \bibliography{literatur}

As said in the initial question the SetTracking command does not solve the issue. I have to disable tracking completly to set it correct. Or else it looks like this:

And this is what I think it should like when done right:

EDIT 2:

Well I fixed the problem. Instead of

\SetTracking{encoding={*}, shape=sc}{40}

I used

\SetTracking{encoding={T1}, shape=sc}{40}

and it worked.

But, as in the comments pointed out, only small caps are kerned, everything else not.

Answer 1

The asterisk in

\SetTracking{encoding=*, shape=sc}{50}

is a placeholder that stands for "default". While for the \Declare... commands the translation of this placeholder takes place at the end of the preamble, for the \Set... commands, it takes places immediately. In your example, this results in the asterisk being translated to OT1, because inputenc -- which changes the default encoding to T1 -- is loaded two lines later.

Therefore, to have the asterisk expand to the default encoding that is actually used in the document, you should load inputenc before microtype.
