Hi Friends, i have a little problem with my Dovecot installation. The normal installation works very well and now i have to configurate dovecot that all member from a domain can access all mailboxes from this domain. I configurate the shared namespace and set the IMAP ACL Flag but i can't abonement the other mailboxes. I get a error in the logs:

My config looks like this: mail:~# dovecot -n # 1.2.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.30-bpo.1-amd64 x86_64 Debian 5.0.4 ext3 log_path: /var/log/dovecot/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mail_uid: 501 mail_gid: 501 mail_location: maildir:/var/mail/%d/%n mail_debug: yes maildir_copy_preserve_filename: yes mbox_write_locks: fcntl dotlock mail_plugins: acl imap_acl namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: shared separator: / prefix: shared/mitarbeiter/%%n/ location: maildir:/var/mails/e-c-o.at/%%n:INDEX=/tmp/%%n list: children lda: postmaster_address: postmaster@e-c-o.at mail_plugins: acl auth_socket_path: /var/run/dovecot/auth-master log_path: /var/log/dovecot/dovecot-deliver-errors.log info_log_path: /var/log/dovecot/dovecot-deliver.log auth default: default_realm: e-c-o.at passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: dovecot-data group: dovecot-data plugin: acl: vfile:/etc/dovecot-acl acl_shared_dict: file:/var/mail/%d/shared-mailboxes.db Do you have any idea why my setup isn't working correct? My users are stored in a LDAP (openLDAP) Server and the login works very well. For completion i post the LDAP-File to. mail:~# grep -v '^ *\(#.*\)\?$' /etc/dovecot/dovecot-ldap.conf hosts = 192.168.1.230 dn = cn=ldapadmin,dc=e-c-o,dc=net dnpass = xxxxxxxx ldap_version = 3 base = ou=smbUser,ou=dc,ou=at,dc=e-c-o,dc=net scope = subtree user_filter = (&(objectClass=posixAccount)(uid=%n)) user_attrs = mail=mail pass_filter = (&(objectClass=posixAccount)(uid=%n)) pass_attrs = uid=user,userPassword=password,
