I found out myself how to control the order: http://wiki2.dovecot.org/Authentication/MultipleDatabases.

still asking how to set up dovecot authentication so *users that authenticate with only their username (i.e. system users) always and only use PAM authentication *users that authenticate with their e-mail-address always and only use SQL authentication

thanks, david

Hi all,

I'm setting a mailserver using dovecot version: 2.1.7. On the server I have a couple of system users using PAM authentication and a lot of virtual users using SQL authentication.

When a virtual user (e.g. david@virtdomain.de) logs in dovecot tries to authenticate the user via PAM and after failing it uses SQL:

Mar 19 11:39:42 orange dovecot: auth-worker(7815): pam(david@virtdomain.de,<ip address>): pam_authenticate() failed: Authentication failure (password mismatch?) Mar 19 11:39:42 orange dovecot: auth: passwd(david@virtdomain.de,<ip address>,<T58IuUTYvgDZbill>): unknown user Mar 19 11:39:42 orange dovecot: imap-login: Login: user=david@virtdomain.de, method=PLAIN, rip=<...>, lip=<...>, mpid=7816, TLS

Could I set up dovecot authentication so *users that authenticate with only their username (i.e. system users) always and only use PAM authentication *users that authenticate with their e-mail-address always and only use SQL authentication ???

Thanks, david
