Hi Everyone interested in this topic. Solution was very simple. All I had to do was to change my ShadowMap camera RefernceFrame to ABSOLUTE_RF_INHERIT_VIEWPOINT.
Thanks to for solving this problem before Robert ;-) Btw. osgShadow::ShadowMap still sets ABSOLUTE_RF maybe we could change it ? I will send proper submission.
