Who cast the Fidelius on James and Lily?

I've long been under the impression that Dumbledore cast the 
Fidelius Charm that was supposed to hide the Potters at Godric's
Hollow, but I can't find any reference to that after a quick perusal 
of PoA.  I ask because it seems odd to me that if Dumbledore cast the
spell, he wouldn't know who the Secret Keeper was.  (Although, I 
suppose that knowledge of who the SK is could be one of the things
hidden by the charm).
