[Dovecot] migrating to 1.0.rc1 + vpopmail

Hi,

We want to migrate to rc1 using vpopmail auth. This is the configuration:

auth default { # Space separated list of wanted authentication mechanisms: # plain login digest-md5 cram-md5 ntlm rpa apop anonymous gssapi mechanisms = plain login passdb vpopmail { # [cache_key=<key>] - See cache_key in PAM for explanation. #args = } userdb vpopmail { } user = root }

And the log shows:

dovecot: Jul 04 13:49:33 Error: Login process died too early - shutting down dovecot: Jul 04 15:51:03 Info: Dovecot v1.0.rc1 starting up dovecot: Jul 04 15:51:04 Error: auth(default): dovecot-auth: Fatal: USERDB envir onment is unset dovecot: Jul 04 15:51:04 Error: Auth process died too early - shutting down dovecot: Jul 04 15:51:04 Error: child 11290 (auth) returned error 89 dovecot: Jul 04 15:55:42 Info: Dovecot v1.0.rc1 starting up dovecot: Jul 04 15:55:43 Error: login: Protocol version mismatch (mixed old and new binaries?) dovecot: Jul 04 15:55:43 Error: Login process died too early - shutting down

What´s happening?

Thank you in advance, Lucas
