Carol responds:

First, I agree with you that Dumbledore knew Harry was going after the
Philosopher's Stone and not only didn't discourage him but to some
extent helped him (the Invisibility Cloak, the Mirror of Erised). He
did not, however, tell him everything he needed to know. He wanted
Harry and his friends to figure it out on their own and to be able to
survive the dangers they were facing. (I don't think that DD himself
specified the tasks; it was JKR who made sure that, for example, the
chess game matched Ron's one special talent!)

However, knowing that Quirrell was "up to something" (as DD obviously
did or he wouldn't have had Snape keep an eye on him) and suspecting
that he was stealing the Philosopher's Stone for Voldemort (as snape
obviously suspected or he wouldn't have talked about where Quirrell's
loyalties lie) isn't the same as knowing that Quirrell is possessed
(which Snape might or might not have found out through Legilimency).
DD would have had sufficient reason to be suspicious of Quirrell when
he came back from Albania(?) stammering and stuttering, perhaps no
longer willing to meet LV's eyes, and still more when he showed up for
the first day of class wearing that smelly turban. Since he hid the
stone at Hogwarts (mentioning the third-floor corridor at the opening
day banquet), it's obvious that he not only expected but *intended*
for Quirrell to try to steal the Stone. (Note that he is the only
teacher of the five key subjects taught to all students--Potions,
Transfiguration, charms, Herbology, and DADA--who was not asked to
help guard the Stone, along with the loyal Hagrid.)

What I don't understand is how DD knew that LV would attempt to steal
the Stone from Gringotts *before* Quirrell put on the turban. (LV
possessed him to "keep a closer eye" on him *after* he failed to steal
the Stone in the Gringotts break-in. It's the sort of thing that
misled many of us into thinking that DD was more or less omniscient.
