  The doping induced insulator-metal transition in $La_{1-x}Sr_{x}TiO_{3}$ is
studied using the ab-initio LDA+DMFT method. Combining the LDA bandstructure
for the actual, distorted structure found recently with multi-orbital DMFT to
treat electronic correlations, we find: $(i)$ ferro-orbital order in the Mott
insulating state without orbital degeneracy, $(ii)$ a continuous filling
induced transition to the paramagnetic metal (PM) with $x$, and $(iii)$
excellent quantitative agreement with published photoemission data for the case
of 6% doping. Our results imply that this system can be described as a
Mott-Hubbard system without orbital (liquid) degeneracy.
