[otrs] AuthenNTLM working, now what?

In the OTRS documentation, I saw that you can use AuthenNTLM to auto authenticate against an AD domain. I have this working, my error_log shows its successfully translating who I am. The only thing ive seen for OTRS is to use: $Self->{'AuthModule'} = 'Kernel::System::Auth::HTTPBasicAuth'; -and- $Self->{'Customer::AuthModule'} = 'Kernel::System::CustomerAuth::HTTPBasicAuth'; However, this isnt working. Does anyone have any insight or help? I am trying to use SSO for OTRS. Thank you, Adam Nielson
