cyrus: how to make it authenticate against unix users?

[Erik Steffl <steffl@bigfoot.com>]

  I would like to set the cyrus authentification to work with unix users
that are defined on the system. How do I set it up? I though it would
work with pam but when I set up pam:

sasl_pwcheck_method: PAM

  I just get an error saying that PAM authentification was not
successful. what do I need to set so that pam uses unix users?

  here's what I have in /etc/pam.d/cyrus (I left out the comments):

auth            required                pam_unix.so nullok
account required                pam_unix.so

  here's the exact error message when I used PAM:

Nov 17 06:33:27 localhost PAM_unix[22917]: authentication failure;
(uid=110) -> erik for imap service

  for some reason I got the following message as well:

Nov 17 06:33:26 localhost imapd[22917]: unable to open Berkeley db
/etc/sasldb: No such file or directory

  I thought this wouldn't be used when using PAM???

  TIA
