Zara:
Albus did come out and say it. He tells Harry he did not teach himn 
Occlumency himself, in order not to tempt Voldemort. Albus feared 
Voldemort would use Harry to spy on him.

I quoted a long segment of the conversation in which he explains this 
(end of OotP) in a response to jkoney's question in this post:

Zara:
I think Lupin's "trick" only worked because Harry wanted to learn the 
specific skill he wheedled Lupin into teaching him. This was clearly 
not the case with Occlumency.
