hi, i would like to have all the emails stored under one system user and system group. i keep user passwords in LDAP. for userdb i wanted to use static. but i keep getting this error:

Error: Error in configuration file /usr/local/etc/dovecot.conf line 909: Unknown setting: userdb Fatal: Invalid configuration in /usr/local/etc/dovecot.conf

i am using version 1.0.13 my /usr/local/etc/dovecot.conf without comments is:

base_dir = /var/run/dovecot/ protocols = imaps imap listen = * disable_plaintext_auth = no shutdown_clients = yes log_timestamp = "%Y-%m-%d %H:%M:%S " ssl_disable = no ssl_cert_file = /etc/apache2/ssl/server.pem ssl_key_file = /etc/apache2/ssl/server.key mail_location = maildir:/home/MAIL/%n mail_privileged_group = mail protocol imap { login_greeting_capability = yes imap_client_workarounds = tb-extra-mailbox-sep }

protocol lda { postmaster_address = postmaster@frontlinedefenders.org hostname = base auth_socket_path = /var/run/dovecot/auth-master } auth_verbose = yes auth_debug = yes auth_debug_passwords = yes auth default { mechanisms = plain passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb static { args = uid=mail gid=mail home=/home/MAIL/%n } auth_userdb = user = mail socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = mail # User running Dovecot LDA group = mail # Or alternatively mode 0660 + LDA user in this group } } } dict { } plugin { }

what do i do wrong? best regards, Wojtek
