[Dovecot] Passdb + single sing on + NTLM + Thunderbird.

[Maria Jose Yañez Dacosta]

Hi!,

I want to use single sign on from Windows with Thunderbird or Outlook using
NTLM.
Which should be placed in the configuration file for passdb?.
Currently I have:

passdb {
  driver = pam
}

But it generates the following error when trying to check mail:
dovecot: auth: pam (pepe, 190 108 101 120): unknown user
If I remove imap passdb just does not work and I add at the end of this
mail the log.
Thank :)
