I tested gluUnProject function in orthogonal projection and it worked well.
I just changed projection method from orthogonal to perspective. And then glUnProject function seems not to work.
Is the gluUnProject applicable only to orthogonal projection ?

No, you may want to do a search in the beginners forum as this is not really advanced.
GluUnProject() should work with any type of projection. Are you sure you are giving it the right parameters?
