Simplification with constraints


Suppose we have a constraint:

a*a+b*b+c*c+d*d==1

What is the most elegant and general way to simplify any expression
considering above constraint for simplification?

For (just a simple) example:

In[]:=simplify[b*b+c*c+d*d]

should give:

Out[]=1-a*a

thanks in advance,
Vladimir
