All, I have a Ubuntu 12.04.2 box running Dovecot 2.0.19. I have it configured for our active directory. WBinfo and ntlm_auth work great. I am trying to get sso to work with ntlm. Gssapi with thunderbird works like it should. I just cant get ntlm with outlook 2010 to work for sso. I get prompted for my password each time I open outlook. I have attached my config for dovecot. Any help would be much appreciated.
