Hi Brad,
Did you forget to call
texture->setShadowComparison(true) ?
Its neccessary for shadow2D and shadow2DProj to work.
setShadowComparison( true ) is equivalent to OpenGL:
glTexParameteri( TextureId , GL_TEXTURE_COMPARE_MODE_ARB,
GL_COMPARE_R_TO_TEXTURE_ARB );
Cheers,
Wojtek

Another thought is what version of GLSL you're invoking. If you use
shadow2D()
to sample the texture, that's good for GLSL 1.20, but is deprecated in 1.30
and
beyond (in which you simply use texture2D() to sample the texture, even if
it's
a shadow texture).
