[Dovecot] NTLM authentication with dovecot.

[Maria Jose Yañez Dacosta]

Hi!,

I'm trying to use single sign on from Windows.
Install dovecot on CentOS 6. The host name is prueba-mail.
I'm using version 2.0.9 because the latest 64-bit gives errors.
But first I wanted to test whether user validation works with telnet.
When I try to try "telnet prueba-mail imap" and try to "a1 LOGIN MyUsername
MyPassword", I get the following error:prueba-mail dovecot: auth:
pam(pepe,190.108.101.120): unknown user.
I show my setup and I appreciate even the minimal support.
