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 :)
