| = Password database extra fields = The primary purpose of a password database lookup is to return the password for a given user. It may however also return other fields which are treated specially: * [wiki:PasswordDatabase/ExtraFields/User user]: Change the username (eg. lowercase it). * [wiki:PasswordDatabase/ExtraFields/AllowNets allow_nets]: Allow user to log in from only specified IPs. * [wiki:PasswordDatabase/ExtraFields/Proxy proxy]: Proxy the connection to another IMAP/POP3 server. * [wiki:PasswordDatabase/ExtraFields/Host host]: Send login referral to client. * [wiki:PasswordDatabase/ExtraFields/NoLogin nologin]: User isn't actually allowed to log in even if the password matches, with optionally a different reason given as the authentication failure message. * [wiki:PasswordDatabase/ExtraFields/NoDelay nodelay]: Don't delay reply to client in case of an authentication failure. How to return these extra fields depends on the password database you use. See the [wiki:PasswordDatabase password database] pages on how to do it. Some passdbs however don't support returning them at all, such as [wiki:PasswordDatabase/PAM PAM]. The password database may also return fields prefixed with `userdb_`. These fields are only saved and used later as if they came from the [wiki:UserDatabase user database]'s extra fields. Typically this is done only when using [wiki:UserDatabase/Prefetch prefetch userdb]. Note that boolean fields are true always if the field exists. So `nodelay`, `nodelay=yes`, `nodelay=no` and `nodelay=0` all mean that the nodelay field is true. With SQL the field is considered to be non-existant if its value is NULL. == Examples == === SQL === dovecot-sql.conf: {{{ password_query = SELECT userid as user, password, 'Y' as proxy, host \ FROM users WHERE userid = '%u' # NOTE: Dovecot doesn't really support line splitting with '\' currently }}} === LDAP === dovecot-ldap.conf: {{{ pass_attrs=uid=user,userPassword=password,proxy,hostName=host }}} === passwd-file === {{{ user:{plain}pass::::::proxy=y host=127.0.0.1 }}} |
