Dovecot won't find users

Hi There,
i have a small problem.

after having a few problems with dovecot i reinstalled it.
but now it won't find the users, created in ispConfig (last version available)

the server is a centOS 5.5.

thats my dovecot config:

Code:

## Dovecot configuration file


listen = *



protocol imap {

}
  
##
## POP3 specific settings
##

protocol pop3 {

}

##
## ManageSieve specific settings
##

protocol managesieve {

}

##
## LDA specific settings
##

protocol lda {
 



auth default {
  mechanisms = plain
  passdb pam {
  }

  # System users (NSS, /etc/passwd, or similiar)

  userdb passwd {
  }

 
  user = root


}


dict {
}


plugin {
 
}

Stripped from every #-Line

i suppose theres the sql-connection missing?

but how do i get them into the file & what's the line for it?

moreover send a mail via postfix not working atm.
But one think after another.


appreciated every answer.
Thanks in advance

 

yes. this has worked.

it only has changed all my individual settings back to default.
But nothing that can't be changed again.

Thack you :3
