[Dovecot] /var/run/dovecot/auth-userdb failed

[Fabrizio Monti]

Thank you very much Daniel,
I solved the problem.
In this moment I have a problem  with a maildir, I used a format
"/home/vmail/%d/%u" and the first user make maildir he is owner
"/home/vmail/%d" and second user don't make a maildir. Now, I look for the
solution.
Best regards.
