Well

I solved it. Altough "mail_uid = mailuser" is defined in dovecot.conf, i must also return an "uid" from the ldap query. Changing:

user_attrs = =home=/var/vmail/%d/%n,mailuserquota=quota=maildir:storage,=mail=maildir:/var/vmail/%d/%n/Maildir

To:

user_attrs = =home=/var/vmail/%d/%n,=uid=mailuser,mailuserquota=quota=maildir:storage,=mail=maildir:/var/vmail/%d/%n/Maildir u

solved the problem. Hope this could be helpful for someone.

Hi

I am running Dovecot 1.1RC4, built from the source packages at the debian repositories (http://xi.rename-it.nl/debian/). When a message is delivered through the LDA, i get this error:

deliver(******@*****): May 02 14:43:28 Fatal: Running as root isn't permitted

These are my config files:

master.cf:

======================================= # Dovecot dovecot unix - n n - - pipe flags=DRhu user=dovecot:mail argv=/usr/lib/dovecot/deliver -d $recipient

dovecot.conf

======================================= protocols = imap pop3 listen = 0.0.0.0 login_greeting = Servidor de correo para preparado. disable_plaintext_auth = no log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot-info.log mail_uid = mailuser mail_gid = mailgroup

# IMAP configuration protocol imap { mail_plugins = quota imap_quota }

# POP3 configuration protocol pop3 { pop3_uidl_format = %08Xu%08Xv mail_plugins = quota }

# LDA configuration protocol lda { log_path = /var/log/dovecot-lda.log postmaster_address = postmaster auth_socket_path = /var/run/dovecot/auth-master mail_plugins = quota cmusieve global_script_path = /home/vmail/globalsievesrc }

# LDAP authentication

auth default {

mechanisms = plain login

passdb ldap {
    args = /etc/dovecot/dovecot-ldap.conf
}

userdb ldap {
    args = /etc/dovecot/dovecot-ldap.conf
}
socket listen {
    master {
        path = /var/run/dovecot/auth-master
        mode = 0660
        user = dovecot
        group = mail
    }

    client {
        path = /var/spool/postfix/private/auth
        mode = 0660
        user = postfix
        group = postfix
    }
}

}

dovecot-ldap.conf

======================================= hosts = 127.0.0.1 auth_bind = yes ldap_version = 3 base = dc=*******,dc=local scope = subtree user_attrs = =home=/var/vmail/%d/%n,mailuserquota=quota=maildir:storage,=mail=maildir:/var/vmail/%d/%n/Maildir user_filter = (&(objectClass=mailAccount)(mail=%u)(mailenable=OK)) pass_attrs = mail=user,userPassword=password pass_filter = (&(objectClass=mailAccount)(mail=%u)(mailenable=OK)) default_pass_scheme = CRYPT

The folder /var/vmail has these permissions:

pdc-server:~# ls -la /var/vmail/ total 16 drwxrwx--- 3 mailuser mailgroup 4096 2008-05-02 14:34 . drwxr-xr-x 16 root root 4096 2008-05-02 14:14 ..

Any idea? Thanks in advance.
