Correct sort of bibliography

Question

• Sorted by first author's last name.
• Works only from one author before works with other authors.
• If there is more than one work, then it needs to be like this: 2007a, 2007b,...

Sort should be like this: Author A:
* Book1 2007
* Book2 2008
* Book 3 2006 other authors

Author B: ...

The minimal working example I have sorts it first by year, then by author last name and sorts the works with other authors after.

If I have multiple works from one author in one year it is correct in the text (shows 2007a etc) but not in the bibliography, shows:

Holson, Laura M. Gnome Core Apps. Oct. 28, 2013. URL :link.
— KDE Core Apps. Oct. 28, 2013. URL : link.
