I'm trying to setup a samba4 with openchange which uses postfix+dovecot+openldap on a ubuntu 12.04.2 system. I can send outgoing emails but incoming emails fail. I looked up the logs and I get:

Mar 5 11:03:48 testerA dovecot: lda(sammy): Error: user sammy: Initialization failed: mail_location not set and autodetection failed: Mail storage autodetection failed with home=/var/mail Mar 5 11:03:48 testerA dovecot: lda(sammy): Fatal: Invalid user settings. Refer to server log for more information.

any idea what I am doing wrong? Any hints, pointers would be much appreciated.

now the user is a virtual user. The /var/mail/sammy exists:

drwxr-sr-x 10 vmail vmail 4096 Mar 4 13:48 sammy lrwxrwxrwx 1 vmail vmail 5 Feb 28 12:12 Sammy -> sammy lrwxrwxrwx 1 vmail vmail 5 Feb 28 12:12 sammy@abertax.com -> sammy lrwxrwxrwx 1 vmail vmail 5 Feb 28 12:13 Sammy@abertax.com -> sammy lrwxrwxrwx 1 vmail vmail 5 Mar 1 15:05 sammy@abx.abertax.com -> sammy

The dovecot configuration is:

# 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-38-generic x86_64 Ubuntu 12.04.2 LTS ext4 disable_plaintext_auth = no lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes log_path = /var/log/dovecot.message log_timestamp = "%Y-%m-%d %H:%M:%S " mail_debug = yes mail_location = maildir:/var/mail/%u mail_privileged_group = mail passdb { driver = pam } passdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } passdb { driver = pam } protocols = imap service auth { unix_listener auth-master { group = vmail mode = 0600 user = vmail } unix_listener auth-userdb { user = vmail } user = root } ssl_cert =

and dovevot-ldap.conf:

uris = ldap://localhost:3389 dn = cn=admin,dc=mydomain dnpass = openchange tls = no ldap_version = 3 base = dc=mydomain scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid user_filter = (uid=%u) pass_attrs = uid=user,userPassword=password pass_filter = (uid=%u)
