Proof of a Dirichlet's theorem using the Riemann zeta function?

Someone could tell me if there is a proof of the Dirichlet's theorem on arithmetic progressions stated below using only the Riemann zeta function $\zeta(s)=\sum_{n=1}^\infty 1/n^s,\;\mbox{Re}(s)>1$? Someone reference?

Dirichlet's Theorem For any two positive coprime integers $a$ and $d$, there are infinitely many primes of the form $a + nd$, where $n \in \mathbb{N}$.

• The comments here raise questions similar to those formulated (and left unanswered) there. – Did Jul 29 '13 at 16:03

• I am pretty sure Patrick meant the usual proof with $L$-functions, but just didn't read the original question carefully. – KCd Jun 25 '13 at 22:04
• I'll admit I didn't see the word 'only'. Why would you be interested in not using $L$-functions? Is it just because you've heard such a proof existed? I edited the question to make it more clear. – Patrick Da Silva Jun 26 '13 at 8:59
• It looks like OP is not only forbidding $L$-functions, but the bit about the real part exceeding 1 suggests that even analytic continuation is out of the question. – Gerry Myerson Jun 26 '13 at 9:06
