Cut-through/direct authentication connection being denied

Question

I'm trying to set up a firewall so an outside user can authenticate to the firewall, then RDP directly to a workstation.
Here's what I've got:
aaa authentication match authmatch outside LOCAL
aaa authentication listener http outside port 5555
access-list authmatch extended permit tcp any host 111.111.111.162 eq 3391
access-list authmatch extended permit tcp any host 111.111.111.162 eq 5555
static (inside,outside) tcp interface 3391 192.168.1.101 3389 netmask 255.255.255.255
I can connect to the web page and authenticate successfully.
6          Aug 21 2012          06:00:33                    222.222.222.146          0 222.222.222.146          0          Authentication succeeded for user 'USER1' from 222.222.222.146/0 to 222.222.222.146/0 on interface outside
But, when I try to RDP in on 3391, it's not hitting the authmatch access list.   It's hitting the outside_access_in access list and it's denied by the default deny.

Why won't it hit the correct access-list?
Thanks,

Hello Marc,
What Karthik is telling you is the following:
-The cut through proxy adds additional control regarding the connections across your firewall, this by using the ASA as a proxy but you still need to allow the traffic on the proper ACL's on the interfaces of your ASA.
So just create an ACL entry into the outside acl permiting traffic to port 3391, of course only the users authenticated will succesfully connect
